Introduction

How Sonar Works

Your Humminbird® Fishing System comes in several different configurations.
See the following list of products, all of which are covered by this manual, to
find your 800/900 Series™ configuration:

Sonar technology is based on sound waves. The Fishing System uses sonar
to locate and define structure, bottom contour and composition, as well as
depth directly below the transducer.

• Humminbird® 858c Combo: Wide screen Fishing System with
DualBeam PLUS™ Sonar and Chartplotting. GPS Receiver included.

Your Fishing System sends a sound wave signal and determines distance by
measuring the time between the transmission of the sound wave and when
the sound wave is reflected off of an object; it then uses the reflected signal
to interpret location, size, and composition of an object.

• Humminbird® 858c DI Combo: Wide screen Fishing System with
Down Imaging™ Sonar, Traditional 2D Sonar, and Chartplotting. GPS
Receiver included.

Sonar is very fast. A sound wave can travel from the surface to a depth of
240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that
your boat can "outrun" this sonar signal.

• Humminbird® 898c SI Combo: Wide screen Fishing System with
Side Imaging® Sonar, DualBeam PLUS™ Sonar, Down Imaging™
Sonar, and Chartplotting. GPS Receiver included.

SONAR is an acronym for SOund and
NAvigation Ranging. Sonar utilizes precision
sound pulses or "pings" which are emitted into
the water in a teardrop-shaped beam.

• Humminbird® 958c Combo: Ultra wide screen Fishing System with
DualBeam PLUS™ Sonar and Chartplotting. GPS Receiver included.
• Humminbird® 958c DI Combo: Ultra wide screen Fishing System
with Down Imaging™ Sonar, Traditional 2D Sonar, and Chartplotting.
GPS Receiver included.

The sound pulses "echo" back from objects in
the water such as the bottom, fish and other
submerged objects. The returned echoes are
displayed on the LCD screen. Each time a new
echo is received, the old echoes are moved
across the LCD, creating a scrolling effect.

• Humminbird® 998c SI Combo: Ultra wide screen Fishing System
with Side Imaging® Sonar, DualBeam PLUS™ Sonar, Down
Imaging™ Sonar, and Chartplotting. GPS Receiver included.

Introduction

The power output is the amount of energy
generated by the sonar transmitter. It is
commonly measured using two methods:

When all the echoes are viewed side by side,
an easy to interpret "graph" of the bottom, fish
and structure appears.

• Root Mean Square (RMS) measures power
output over the entire transmit cycle.
• Peak to Peak measures power output at the
highest points.
The benefits of increased power output are
the ability to detect smaller targets at greater
distances, ability to overcome noise, better
high speed performance and enhanced depth
capability.

The sound pulses are transmitted at various
frequencies depending on the application.
Very high frequencies (455 kHz) are used for
greatest definition, but the operating depth is
limited. High frequencies (200 kHz) are
commonly used on consumer sonar and
provide a good balance between depth
performance and resolution. Low frequencies
(83 kHz) are typically used to achieve greater
depth capability.

20°
200kHz

83kHz

The Fishing System uses a 200/83 kHz
DualBeam PLUS™ sonar system with a wide
(60°) area of coverage. DualBeam PLUS™
sonar has a narrowly focused 20° center
beam, surrounded by a second beam of 60°,
expanding your coverage to an area equal to
your depth. In 20 feet of water, the wider
beam covers an area 20 feet wide.

The 898c SI Combo and 998c SI Combo use
Side Imaging® sonar to provide a wide yet
precise survey of a large area of water,
including detailed bottom topography and
fish-attracting structure orientation. The
Side Imaging® transducer returns are
processed into an image similar to an aerial
photograph.

DualBeam PLUS™ sonar returns can be
blended together, viewed separately, or
compared side-by-side. DualBeam PLUS™ is
ideal for a wide range of conditions - from
shallow to very deep water in both fresh and
salt water. Depth capability is affected by
such factors as boat speed, wave action,
bottom hardness, water conditions, and
transducer installation.

Typically, the Side Imaging® sonar can
search an area that is 480 feet wide (240 to
each side), with a typical depth
performance of 150 feet when the Side
Imaging® Sonar frequency is set for
455 kHz. The side beams can be operated at
one of two frequencies: 455 kHz or 800 kHz.
Selecting 800 kHz produces the sharpest
image, but the search area to each side
and the depth capability are limited as
compared to the 455 kHz frequency. See
What’s on the Side Imaging® Display and
Understanding Side Imaging® for more
information.
The Side Imaging® transducer also
provides down imaging displays on the
screen. See What's on the Down
Imaging™ Display for more information.

Your 858c DI/958c DI Fishing System uses
Down Imaging™ technology. The Down
Imaging™ transducer scans the water
with razor-thin, high-definition beams.
The beams are wide (side to side) but very
thin front to back.

the best overall image quality and depth.
Select 800 kHz for the sharpest image.
See Down Imaging™ X-Press™ Menu:
Imaging Frequency for more information.

90° Total Coverage
Bottom Coverage = 2 x Depth

Your Fishing System supports the
optional-purchase QuadraBeam PLUS™
transducer. QuadraBeam PLUS™ sonar
provides a wide (90°) area of coverage.
QuadraBeam PLUS™ starts with two
fan-shaped 35° 455 kHz Side Structure
locating sonar beams to spot fish, bait,
and structure to the left and right of the
boat over an area of the bottom that’s
always equal to twice your depth.
For a detailed view below the boat,
QuadraBeam PLUS™ uses DualBeam
PLUS™ technology, with precision 20°
and wide 60° beams. QuadraBeam
PLUS™ finds more fish faster, and can
even tell you where to put your bait by
showing if fish are to the left, right, or
directly beneath your boat.

The transducer also uses conical beams to
provide data in traditional 2D format (see
What’s on the Sonar View). Select 455

factors as boat speed, wave action,
bottom hardness, water conditions, and
transducer installation.

Universal Sonar 2

GPS was originally intended for military use; however, civilians may also take
advantage of its highly accurate position capabilities, typically within +/- 4.5
meters, depending on conditions. This means that 95% of the time, the GPS
receiver will read a location within 4.5 meters of your actual position. Your
GPS Receiver also uses information from WAAS (the Wide Area
Augmentation System), EGNOS (the European Geostationary Navigation
Overlay Service), and MSAS (the MTSAT Satellite Augmentation System)
satellites if they are available in your area.

Your Fishing System supports Universal Sonar 2, a state-of-the-art,
integrated and protected transducer that is built into the lower unit of
Minnkota trolling motors. With Universal Sonar 2, all wiring is concealed
inside the indestructible composite shaft—out of sight and out of harm’s
way, with no clamps, ties, or exposed wires. Universal Sonar 2 features new
temperature sensing and the performance of DualBeam PLUS™ technology.
An expanded view and greater bottom detail gives you a totally new
perspective of the water below, along with optimal sonar performance to
help you find fish.

The following GPS functionality is currently supported by the Fishing System
when it is connected to the included GPS receiver:
• View current position

How GPS and Cartography Work

• View current track (breadcrumb trail)

Your Fishing System also supports GPS (Global Positioning System) and
chartplotting. It uses GPS and sonar to determine your position, display it on
a grid, and provide detailed underwater information.

• View precision speed and heading from your GPS receiver
• Save tracks, waypoints, and routes
• Travel a route and navigate from one waypoint to the next.

GPS uses a constellation of satellites that
continually send radio signals to the earth. The
GPS receiver on your boat receives signals from
satellites that are visible to it. Based on time
differences between each received signal, the
GPS receiver determines its distance to each
satellite. With distances known, the GPS
receiver mathematically triangulates its own
position. With once per second updates, the
GPS receiver then calculates its velocity and
bearing.

See Chart View and SD Memory Card Slots: Add Maps to Your Fishing
System for more information.

Cursor information is displayed at the top of
the screen.

Understanding the Sonar Display

Real Time Sonar (RTS™) Window

It is important to understand the significance of
the display. The display does NOT show a literal
3-dimensional representation of what is under
the water. Each vertical band of data received
by the control head and plotted on the display
represents something that was detected by a
sonar return at a particular time. As both the
boat and the targets (fish) may be moving, the
returns are only showing a particular segment
of time when objects were detected, not exactly
where those objects are in relation to other
objects shown on the display.

A Real Time Sonar (RTS™) Window appears on the right side of the display
in the Sonar View only. The RTS Window™ always updates at the fastest rate
possible for depth conditions and shows only the returns from the bottom,
structure and fish that are within the transducer beam. The RTS Window™
plots the depth and intensity of a sonar return. (See Sonar Menu Tab: Real
Time Sonar (RTS™) Window).
The Narrow RTS Window™
indicates the sonar intensity
through the use of colors.
Red indicates a strong return
and blue indicates a weak
return. The depth of the
sonar return is indicated by
the vertical placement of the
return on the display depth
scale.

The returned sonar echoes are displayed on the screen. As a new echo is
received, the historical data scrolls left across the display.

The Wide RTS Window™
indicates the sonar intensity
through the use of a bar
graph. The length of the
plotted return provides an
indication of whether the
return is weak or strong. The
depth of the sonar return is
indicated by the vertical
placement of the return on
the display depth scale.

SwitchFire™
SwitchFire™ controls how the sonar returns are displayed in the Sonar
Views. SwitchFire™ settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam
so more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the
transducer beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™
for more information.

Structure ID® represents weak returns in blue and strong returns in red.

The RTS Window™ continues to update in Freeze Frame. To return to a
scrolling display and exit Freeze Frame, press the EXIT key. Freeze Frame is
available in the Sonar, Split Sonar, and Sonar Zoom Views.

Instant Image Update
Instant Image Update - You can change a variety of sonar menu settings
(such as Sensitivity or Upper Range), and the adjustments will be shown
instantly on the screen.

WhiteLine™ highlights the strongest sonar returns in white, resulting in a
distinctive outline. This has the benefit of clearly defining the bottom on the
display.

Sonar Bottom Presentation
As the boat moves, the unit charts the changes in depth on the display to
create a profile of the Bottom Contour. The type of bottom can be
determined from the return charted on the display. A Hard Bottom such as
compacted sediment or flat rock appears as a thinner line across the display.
A Soft Bottom such as mud or sand appears as a thicker line across the
display. Rocky Bottoms have a broken, random appearance.
NOTE: A sloping bottom will be represented as a thicker line across the display.
Harder bottoms typically will be displayed with red and softer bottoms typically
will be displayed with blue.
What’s on the Sonar Display

What’s on the Side Imaging® Display (898c SI and 998c SI only)
Side Imaging® displays a number of easily recognizable features that allow for accurate interpretation of bottom contour and structure. For Side Imaging®, the bottom
composition determines the intensity of the sonar return. For example, rock and gravel provide a clearer sonar return than mud and sand because of their relative
density. Upward slopes that face the transducer reflect sonar better than downward slopes that face away from the transducer. You can find a number of easily
recognizable features on the Side Imaging® display that allow for accurate interpretation of bottom contour and structure, including the following items:
8 Water column - Shows the relative depth of the water under the
1

boat at a given time. Variations in the width of the water column
show variations in the distance to the bottom as the boat passes

area and can be more valuable for interpretation than the sonar
reflected by the object itself. Use shadows to help you see the
image in 3 dimensions, oriented in space. You can gain insight
into the actual shape of an object, or the depth to which it has
sunk into the bottom, through shadows on the display. Objects
standing on the bottom cast a sonar shadow. The longer the
shadow, the taller the object. Fish also cast shadows. You can
use the shadow to interpret how close the fish is to the bottom.

10 Topography Changes - The light part of the screen shows where
the beam is hitting hard bottom or rising terrain. The dark part of
the screen indicates soft bottom (sand, mud) or descending
terrain.

What’s on the Side Imaging® Display

Understanding the Side Imaging® Display

Each time the unit pings, a strip of data representing all the echoes
received by the transducer are put together on the display to form
the image that you see.

It is important to understand how Side Imaging® technology produces the
display. The images you see on the display are produced using sonar
technology. The special transducer projects three distinct beams – one beam
facing down and two beams pointing out to the side.

The rows closest to the boat icon at the top of the view are the
most recent sonar data. The information is scrolled down the screen
as new data, drawn at the top of the screen, becomes available.

Down Beam is aimed directly below the boat and provides conical
coverage.
Side Beams are aimed at right angles to the path of the boat. The
side beam coverage is very thin from front to back, yet very wide top
to bottom. The narrow aspect (front to back) of the beam illuminates
a small strip of the bottom perpendicular to the direction of the boat.

Side Imaging
Sonar echoes are
first displayed at
the top of the
screen, and
historical data
scrolls down the
display as new
information is
received.

Side Imaging® Representation

The main benefit of Side Imaging® sonar to anglers is that it provides an
overall survey of a large area of water. This gives you a better understanding
of the bottom topography and how structure is oriented for more efficient
fishing.
Saltwater anglers pick up precise details of popular fishing structure like
wrecks, reefs, humps and drop-offs, as well as being able to spot bait balls
in open water. Freshwater anglers can see fish-attracting structure such as
timber, stumps, rocks and creek beds.

As the unit pings, a strip of data is displayed at the top of the Side Imaging® view.

What’s on the Side Imaging® Display

Side Imaging® Frequencies and Coverage

455 kHz provides maximum coverage with 180° total beam width

Side Imaging® sonar uses two very precise sonar beams that are directed to
either side of the boat. The beams “illuminate” the bottom contour,
structure, and fish, and the results are displayed in a “picture-like” image on
the screen.
• Frequencies: The side beams can be operated at one of two
frequencies: 455 kHz or 800 kHz. Your Side Imaging® transducer also
provides DualBeam PLUS™ at 200/83 kHz. Selecting 800 kHz
produces the sharpest image, while selecting 455 kHz provides
greater bottom coverage area.

800 kHz provides highest resolution with 130° total beam width

• Side Imaging® Beams are extremely narrow from front to back, and
provide “thin slices” of the bottom for high resolution imaging.
• Side Imaging® Range: 240 feet to each side, with a total side
coverage of 480 feet, with a depth limitation of 150 feet, depending
on the contour of the bottom and when the side beam frequency
selection is set to 455 kHz.

What’s on the Side Imaging® Display

For Best Performance

Beam Coverage: When there is an area directly under the boat that does not
have SI beam coverage, this area will be covered by the standard 200/83 kHz
down-looking beam and displayed in the Sonar views. The net effect of this,
on the display, is that a single object may appear as two separate entities,
when in reality, it is one continuous object. See Submerged Bridge: A Closer
Perspective and the Submerged Bridge: Alternative Perspective
illustrations for examples of this.

Use the following tips and examples to help you interpret the Side Imaging®
display.
Side Imaging® Tips
Boat speed: 2 to 6 mph
Straight line navigation

See humminbird.com and sideimaging.com for a side imaging sonar
tutorial and additional information.

Minimum turning time and wave turbulence
Boat speed: Side Imaging® is best performed at boat speeds between 2 to 6
mph. If the boat is stationary, the same information is displayed over and
over. If the boat is moving very quickly, there will be gaps between the strips
of information. The best boat speed to use will depend on the side range
selected. Slower speeds are good for longer ranges, while faster speeds can
be used at shorter ranges.
Boat navigation: It is important to understand that when the boat turns,
successive beam strips to one side will begin to overlap and the strips on the
other side will fan out, providing some distortion to the image. Because of
this, the best imaging performance is produced by straight line navigation
and minimal side-to-side boat motion (i.e. wave induced, etc.) This applies to
navigation by either the main engine or the trolling motor. Minimize turning
time and avoid wave action that induces large side-to-side rocking of the
boat. For example, if there is a lot of wave activity, try to move the boat so
that it is perpendicular to the waves instead of parallel with the waves in
order to minimize the side-to-side rocking of the boat.

What’s on the Down Imaging™ Display (858c DI, 958c DI, 898c SI, and 998c SI Combo models only)
Down Imaging™ uses unique sonar technology to provide information about the area directly below your boat. The razor-thin, high- definition profiling beams
produce the detailed sonar data that you see on the display. Down Imaging™ reveals a variety of recognizable features so that you can interpret the structure
and bottom contour, including the following items:
7 Speed - If a GPS Receiver or Temp/Speed accessory is

8 Structure

Triplog

11
3

9 Shadows - Result from a lack of reflected sonar from a
particular area and can be as valuable for interpretation than
the sonar reflected by the object itself. Use shadows to help
you see the image in 3 dimensions, oriented in space. You can
gain insight into the actual shape of an object, or the depth to
which it has sunk into the bottom, through shadows on the
display. Objects standing on the bottom cast a sonar shadow.
The longer the shadow, the taller the object. Fish also cast
shadows. You can use the shadow to interpret how close the
fish is to the bottom.

10 Topography Changes - The light part of the display shows

where the beam is hitting hard bottom or rising terrain. The
dark part of the display indicates soft bottom (sand, mud) or
descending terrain.

11 Bottom Return - Use the appearance of the bottom return to

determine bottom hardness. Rock and gravel provide a clearer
sonar return than mud and sand because hard objects reflect
sonar better than soft objects.

What’s on the Down Imaging™ Display

Understanding the
Down Imaging™ Display

Down Imaging™ Sensitivity
Use Down Sensitivity or Imaging Sensitivity to control how the sonar
returns appear on the display. Increase the sensitivity to reveal weaker
returns that may be of interest, especially in very clear water or greater
depths. Decrease the sensitivity to eliminate the clutter from the display that
is sometimes present in murky or muddy water. See the Down Imaging™
X-Press™ Menu for more information.

The images you see on the Down
Imaging™ display are produced
using sonar technology. Each time
the unit pings, a strip of data
representing all the echoes
received by the transducer are put
together on the display to form the image that you see. Like traditional 2D
Sonar, the sonar history scrolls left across the screen.

Freeze Frame and Active Cursor
Freeze Frame and Active Cursor - Press any arrow on the 4-WAY Cursor
Control key, and the screen will freeze and a cursor will be displayed. Use the
4-WAY Cursor Control key to move the cursor over a sonar return, and the
depth of the sonar return will be displayed in the cursor dialog box.

Interpreting the Display
Down Imaging™ beams “illuminate” the bottom contour, structure, and fish.
The beams are wide (side to side) but very thin front to back.

Zoom: Use the zoom keys on your control head to see the returns near the
cursor location at a higher magnification. See Views: Down Imaging™ View
for more information.

Use the light and dark parts of the display to interpret the objects under your
boat as follows:
• Dark shades represent soft returns (mud, sand) or descending
terrain.
• Light shades represent denser terrain (timber, rocks) or rising terrain.
A very hard bottom may appear as white on the display.
• White Streaks or Clouds may represent fish on the display.
• Shadows are not caused by light but by the lack of a sonar return.
Objects standing on the bottom cause a sonar shadow to appear on
the display. The longer the shadow, the taller the object. Fish may
also cast shadows. You can use the shadow to interpret where the
fish or object is located in relation to the bottom.

Chart Orientation

Viewing Cartography

All of the chart views allow you to choose the orientation of the chart. In
both orientations, the view pans automatically so that the boat is always
centered on the display.

In the Chart and Combo Views, there are several cartography-related
functions that you can access using various keys.
Panning: Use the 4-WAY Cursor Control key to move the chart around on the
display in the direction of the key being pressed. When you do this, a bull's
eye cursor is drawn at the center of the screen and is linked to the boat by
a gray line, even if the boat is off the screen. At the same time, a cursor
dialog box is displayed at the top of the screen with the distance and bearing
from the boat to the cursor position and the latitude/longitude coordinates
of the cursor. When the cursor is active on the display, you can also use the
4-WAY Cursor Control key to move the cursor diagonally.

NOTE: The Chart Orientation setting does not apply to the Bird’s Eye View.

• North-Up: True North is shown at the top of the display. Objects
located to the north of the boat are drawn above the boat.
• Course-Up: The direction of motion of the boat is shown at the top
of the display. Objects ahead of the boat are drawn above the boat.
When the boat is stationary, it is drawn as a circle.

Chart View with Cursor Present

When the boat is in motion, it takes on a boat shape, pointed
in the direction of motion (always Up in the Course-Up
orientation).

Viewing Cartography

Zooming: Press the Plus (+) key to Zoom In and the Minus (-) key to Zoom
Out to see the cartography at different magnification levels. The zoom level
is indicated on the left side of the display. If you zoom in beyond the available
chart data, the display will go into Overzoom mode whereby the last
available chart data is amplified to reflect the level selected. If you zoom in
so far that no cartography is available, a lat/long grid will be drawn instead.

Nearest Port: The position and services information for the nearest port to
your present position will be displayed. Press the EXIT key to remove the
information box and the cursor bull’s eye will be centered over the port
position. The cursor information boxes will indicate the distance and bearing
to the port from your present position.
Nearest Tide Station: Tide information for the nearest tide station to your
present position will be displayed. This includes the position of the station
and the times of the high and low tides for today’s date. A tide graph is also
displayed showing the rise and fall of the tides for the 24 hour time period
encompassing the date. You can change the date to look at tide information
before or after the date displayed by pressing the LEFT or RIGHT Cursor key
respectively. Press the EXIT key to remove the information box, and the
cursor bull’s eye will be centered over the tide station position. The cursor
information boxes indicate the distance and bearing to the tide station from
your present position.

Screen Snapshots and Recording Icons: When a waypoint is created while
Screen Snapshot and Recording is active, the waypoint will appear as a
snapshot icon or recording icon in chart views. See Views: Snapshot and
Recording View for more information.
Chart Info: Press the INFO key to get detailed information about the chart.
If the cursor is active, you will see information about the chart objects
located near the cursor.
If the cursor is not active, the Chart Info
submenu will appear. Use the 4-WAY Cursor
Control key to select the Nearest Port, the
Nearest Tide Station, or the Nearest Current
Station and see information about any of
these objects.

Nearest Current Station: Current information for the nearest current station
to your present position will be displayed. This includes the position of the
station and the current changes for today. Two graphs are also presented
that show the time, direction, and flow speed of the current changes for the
24 hour time period of today’s date. You can change the date to look at
current information before or after the date displayed by pressing the LEFT
or RIGHT Cursor key respectively. Press the EXIT key to remove the
information box, and the cursor bull’s eye will be centered over the current
station position. The cursor information boxes will indicate the distance and
bearing to the current station from your present position.

NOTE: The built-in UniMap™ does not contain
any Port, Tide, or Current information. This
information is only available from optionalpurchase SD cards.

Introduction to Navigation

Waypoints, Routes and Tracks

Use your Fishing System to mark waypoints at areas of interest and to
navigate to those waypoints via a savable route. A route represents the
shortest intended distance between waypoints. You can also view and save
tracks, which represent the actual path of the boat.

Waypoints, Routes, and Tracks

Waypoints are stored positions (latitude, longitude) that allow you to mark
areas of interest or navigation points (i.e. a marker buoy, dock, or fishing
hole). Your Fishfinder can store up to 3000 waypoints.

5

7

Routes link two or more waypoints together to create a path for navigation
and are used in trip planning. You can link individual waypoints together by
using the GOTO key. A route represents your intended navigation and shows
the shortest path from each waypoint to the next. As you travel a route,
staying on the route line is the most efficient way to get to your destination,
although you should always look out for obstacles not shown on the chart.
Your Fishing System can store up to 50 routes that can each contain up to
50 waypoints.

Man Overboard (MOB) Navigation

MOB Navigation

As soon as you know that you have a man overboard (MOB), you should
activate MOB navigation to maximize the chances for a successful rescue.
MOB navigation allows you to create an MOB waypoint to locate the point
at which your man went overboard and the relation of the boat to that point.

Activate MOB navigation: Press and hold the GOTO key for more than 1.5
seconds to activate the Man Overboard (MOB) function.

3
5

When MOB is activated, a MOB waypoint is created at the boat's current
position, regardless of whether the chart cursor is active or not. The MOB
waypoint has a large, distinctive icon. Once MOB is activated, any current
navigation will be cancelled and the current route will be discarded without
user notification. MOB navigation will begin immediately, and the MOB View
will show the following:

1
1 Position where man fell overboard
2 Elapsed time since MOB was activated
3 Boat icon

• The view will switch to the Chart View, and the elapsed time since
MOB was activated will be displayed.
• A line will be drawn from the boat's current position to the MOB
waypoint, and the MOB waypoint will be targeted.

Target surrounding MOB waypoint 4
MOB waypoint 5

It is not possible to re-activate MOB or modify the current route without
first canceling MOB navigation. The Off Course trigger is also disabled and
the Off Course Alarm circle is not drawn. Any press of the GOTO key, or
selection of a GOTO menu option, will cause an error beep and a short
message will be displayed that will disappear after 2 seconds.

• The latitude/longitude position of the MOB waypoint will be
displayed in an additional information box.
Cancel MOB Navigation: From the Navigation X-Press™ Menu, select
Cancel MOB, and press the RIGHT Cursor key. Canceling MOB navigation
removes the route and any waypoints created using the GOTO key but does
not remove any saved routes from memory.

The Menu System

Start-Up Options Menu

The Menu System is divided into easy-to-use menu modules as follows:

Press the MENU key during the power on sequence to view the Start-Up
Options Menu, and select one of the modes described on the following
pages. Also, see Power On the Control Head for more information.

• Start-Up Options Menu: Press the MENU key during the power on
sequence to view the Start-Up Options Menu. From the Start-Up
Options Menu, you can choose the following Fishfinder Modes:
Normal, Simulator, and System Status.

Start-Up Options Menu

• X-Press™ Menu: The X-Press™ Menu provides a shortcut to the
most frequently-used settings, and the options on the X-Press™
Menu correspond with the current view.
• Main Menu: The Main Menu is a standard set of menu settings
which are organized under the following tabbed headings: Alarms,
Sonar, Navigation, Chart, Setup, Views, and Accessories.
NOTE: The X-Press™ Menu(s) and the Main Menu options can also be
expanded or simplified by setting the User Mode to Advanced or Normal (see
Main Menu: User Mode).

Normal
Use Normal for on-the-water operation with a transducer connected. If a
functioning transducer is connected, Normal operation will be selected
automatically at power up, and your Fishing System can be used on the water.
To exit Normal operation, power off your Fishing System.

total hours of operation, and the input voltage.
Self Test Screen

We recommend going through this manual while using the Simulator, since
all of the menus function and affect the display in the same way as they
would in Normal operation. Any menu changes you make will be saved for
later use.
• A message will appear often on the display to indicate Simulator
mode.
• To exit Simulator, power off your Fishing System.
NOTE: It is important to select Simulator manually from the Start-Up Options
Menu as opposed to letting the Fishing System enter Simulator automatically (as
it will if a transducer is not connected and you do nothing during power up).

Sonar X-Press™ Menu

Sensitivity

Upper Range

Settings: Low = 1, High = 20; Default = 10

(Advanced: Sonar, Split Sonar and
Active Sonar Side Views only)

Sensitivity controls how much detail is shown on the display and will adjust
the sensitivity of all sonar frequencies.

Sensitivity at Low

Settings: 0 to 1490 feet or 0 to 497 meters
[International models only], Default = 0 ft

Decrease the sensitivity to eliminate the
clutter from the display that is sometimes
present in murky or muddy water. If
Sensitivity is adjusted too low, the display
may not show many sonar returns that
could be fish.

Upper Range sets the shallowest depth range that will be displayed on the
Sonar, Split Sonar, and Active Sonar Side Views. Upper Range is often used
with Lower Range.
For example, if you are only interested in the area between 20 and 50 feet
deep, you should set the Upper Depth Range to 20 and the Lower Depth
Range to 50. The Sonar View will then show the 30 foot area between 20
and 50, and will not show the surface or the bottom (assuming the bottom
is deeper than 50 feet), and will show greater detail for that area between
20 and 50 feet.

When operating in very clear water or
greater depths, increase the sensitivity to
see weaker returns that may be of interest.
If the sensitivity is adjusted too high, the
display may become too cluttered.
Sensitivity at Medium

NOTE: A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the manual settings entered.

NOTE: The Sensitivity setting is a global setting
and will adjust the sensitivity of all sonar
frequencies.
.

Sensitivity at High

Sonar X-Press™ Menu

Lower Range

Chart Speed

Settings: Auto, 10 to 1500 feet, 3 to 500 meters
[International Models only]; Default = Auto

Settings: 1-10, where 1 = Slow, 10 = Fastest
Default = 5

Lower Range sets the deepest depth range that will be displayed by the unit.

Chart Speed determines the speed at which the sonar information moves
across the display, and consequently the amount of detail shown.

Auto: The Lower Range will be adjusted by the unit to follow the bottom
automatically. Auto is the default setting.

A faster speed shows more information and is preferred by most anglers;
however, the sonar information moves across the display quickly. A slower
speed keeps the information on the display longer, but the bottom and fish
details become compressed and may be difficult to interpret. Regardless of
the Chart Speed setting, the RTS Window™ will update at the maximum rate
possible for the depth conditions.

Manual: You can adjust the Lower Range to lock the unit on a particular
depth. M will be displayed in the lower right corner of the screen to
indicate the unit is in Manual mode. Adjust the Upper and Lower Range
together to view a specific depth range, especially when looking for fish or
bottom structure.

Quad Layout

For example, if you are fishing in 60 feet of water but are only interested in
the first 30 feet (surface to a depth of 30 feet) you should set the Lower
Depth Range limit to 30. The display will show the 0 to 30 foot range,
which allows you to see a more detailed view than you would see if the
display went all the way to the bottom.

(with optional-purchase QuadraBeam PLUS™
Transducer, Side Beam View only)
Settings: Default, Classic, Slanted, Default = Default

Quad Layout allows you to choose how sonar information is displayed in the
Side Beam View. The Side Beam View displays sonar data from the left and
right 455 kHz beams, as well as the 200 kHz down-looking beam. The sonar
data can be displayed in any of the following layouts by changing the Quad
Layout setting: Default, Classic, and Slanted. See Views: Side Beam View for
more information.

NOTE: A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the settings entered manually.

NOTE: Quad Layout is only available when an optional-purchase QuadraBeam
PLUS™ transducer is attached and the Side Beam View is active (see Sonar
Menu Tab: Transducer Select).

(Sonar Zoom View only)

(only when Navigating)

Settings: Off, On; Default = Off

Settings: Press the RIGHT Cursor key and follow
screen instructions.

Bottom Lock changes the mode of the zoomed view in the Sonar Zoom
View. Bottom Lock continuously graphs the bottom at a constant point on
the display regardless of changes in depth. This “flattens“ out the bottom
contour but is effective at showing fish on or near the bottom.

Cancel Navigation discards the current route and exits Navigation Mode.
This menu option will only appear when you are currently navigating a route.
This will not delete a previously-saved route.

Bottom Range
(Sonar Zoom View only, when Bottom Lock is On)
Settings: 10 - 60 feet, 2-10 fathoms, or 3-20 meters
[International Models only], Default = 15 feet

Bottom Range allows you to control how much of the water column,
measured up from the bottom, is shown in the Sonar Zoom View. Choose a
small value to see low-lying bottom structure or details of the bottom return.
Choose a larger value to see large structure in deeper water.
NOTE: It is possible to set the Bottom Range to be greater than the depth. In this
case, you may see surface clutter in a wavy band that mirrors changes in the
depth.

SI Side

SI Enhance

Settings: Left, Both, Right, Default = Both

Settings: Press the RIGHT Cursor key.

SI Enhance allows you to adjust your Side Imaging® View in four categories:
Sensitivity, Contrast, Sharpness, and Contour Mode.

SI Side sets which transducer beam from the Side Imaging® beams will be
shown on the display.

Whether you’re searching the Side Imaging® data for fish or certain bottom
contour, the most effective settings will vary with the situation. The display
will update as you adjust each category. SI Enhance can also be used during
Recording Playback (see Snapshot and Recording View).

SI Sensitivity
Settings: Auto, 1 to 20, where Low = 1,
High = 20, Default = 10

SI Sensitivity controls how much detail is shown on the display.
Increase the SI Sensitivity to reveal weaker returns that may be of interest,
especially in very clear water or greater depths. A high SI Sensitivity setting
shows more sonar returns from small baitfish and suspended debris in the
water; however if the SI Sensitivity is adjusted too high, the display may
become too cluttered.

SI Enhance Submenu

• Sensitivity - Controls how much detail is shown on the display.
When operating in very clear water or greater depths, increased
sensitivity shows weaker returns that may be of interest. Decreasing
the sensitivity eliminates the clutter from the display that
is sometimes present in murky or muddy water. (1 to 20, where
Low = 1, High = 20, Default = 10)

Decrease the SI Sensitivity to eliminate the clutter from the display that is
sometimes present in murky or muddy water. If SI Sensitivity is adjusted too
low, the display may not show many sonar returns that could be fish.

NOTE: The Sensitivity can be adjusted from the SI Enhance dialog box or the Side
Imaging® X-Press™ Menu. The Sensitivity setting is provided here so that you can
easily adjust the Side Imaging® data with the other settings. See Side Imaging®
X-Press™ Menu: SI Sensitivity for more information.

Side Imaging® X-Press™ Menu

SI Range

• Contrast: Accents the light and dark parts of the Side Imaging® data
to provide greater definition. (1-20, Default = 10)

Settings: 6 to 360 feet, or 2 to 120 meters
[International Models only], Default = 150 feet, 50
meters

• Sharpness: Filters the view and sharpens the edges of the Side
Imaging® data. (Low (L), Medium (M), High (H), Default = Off)

SI Range sets the deepest range that will displayed in the Side Imaging®
views. The range must be set manually.

• Contour Mode: Controls how the water column is displayed in the
Side Imaging® Views. In the normal display with the Contour Mode
off, the water column is displayed on the view. The location of a
target on the display is based on the slant range to the target.

Choose a low range number to focus on a shorter distance of the water
column and see greater detail on the screen. Choose a higher range number
to view farther into the water and see an overview of details on the screen.

When Contour Mode is turned on, the bottom is graphed at a
constant point on the display, regardless of changes in depth. The
Side Imaging® beams are divided by a vertical line. The water column
is removed from the view, which allows the display to show targets
at their linear horizontal distance. The location of a target may be
easier to interpret when the water column is removed. (Off, On;
Default = Off)

Chart Speed
Settings: 1- 10, where 1 = Slow, 10 Fastest,
Default = 5

Chart Speed determines the speed at which the side sonar information
moves down the display, and consequently the amount of detail shown. A
faster speed shows more information in the Side Imaging® Views and is
preferred by most anglers; however, the sonar information moves across the
display quickly. A slower speed keeps the information on the display longer,
which allows you to see an entire area.

NOTE: If both SI Range Lines and Contour Mode are turned on, the SI Range
Lines will remain on the display, but the individual range numbers are not
available (see Sonar Menu Tab: SI Range Lines).

Surface Clutter adjusts the filter that removes surface clutter noise caused
by algae and aeration. The lower the setting, the less surface clutter will be
displayed.

SwitchFire™ controls how the sonar returns are displayed in the Sonar
Views.
Choose Max Mode to see only raw sonar returns on the display. When Max
Mode is selected, you will see the maximum sonar information available
within the transducer beam, so more fish arches and better jig tracking are
shown.
Choose Clear Mode to see less clutter and more fish size accuracy on the
display. When Clear Mode is selected, the clutter is filtered, and sonar
returns are interpreted to provide more details about the objects within the
transducer beam, regardless of their location. In other words, a large arch on
the display means a large fish has been detected.

Surface Clutter

Sonar Menu Tab

Fish ID+™
Settings: Off, On; Default = Off

Fish ID+™ uses advanced signal processing to interpret sonar returns and
will display a Fish Symbol when very selective requirements are met. When
a fish is detected, a fish icon and its depth are displayed above the return
that has been classified as being a fish. Three different fish size icons
represent the intensity of the sonar return and provide an indicator of
relative fish size.
In DualBeam PLUS™ models (858c, 958c, 898c SI, and 998c SI), targets
detected in the 200 kHz narrow beam are represented as orange fish
symbols, and targets detected in the 83 kHz wide beam are represented as
blue fish symbols.

Transducer Cone and Fish Arches

Fish ID Sensitivity
Settings: Low = 1, High = 10; Default = 5

Narrow beam
orange fish symbols

Fish ID Sensitivity adjusts the threshold of the Fish ID+™ detection
algorithms. Selecting a higher setting allows weaker returns to be displayed
as fish. This is useful for identifying smaller fish species or baitfish. Selecting
a lower setting displays fewer fish from weak sonar returns. This is helpful
when seeking larger species of fish.

Wide beam
blue fish symbols

In Down Imaging™ models (858c DI and 958c DI), targets detected in the
455 kHz conical beam are represented as orange fish symbols, and targets
detected in the 200 kHz conical beam are represented as blue fish symbols.

Fish ID Sensitivity is used in conjunction with Fish ID+™. Fish ID+™ must be
On for Fish ID Sensitivity to affect the ability of the Fishfinder to identify
sonar returns as fish.

When Fish ID+™ is turned off, the Fishfinder shows only the raw sonar
returns on the display. These returns will often result in “arches“ forming on
the display, indicating potential targets. Due to the transducer beam angle,
the distance to a fish decreases as the fish moves into the beam, and then
increases as it moves out again, creating a Fish Arch when this distance
change is shown on the display. Boat speed, chart speed, and the position
of the fish within the sonar beam greatly affect the shape of the arch.

Noise Filter

Max Depth controls the down beam reading. The SI Range (Side Imaging®
Range) controls the side beams and down beam reading at the same time.
If SI Range is set to a deeper range than the Max Depth setting, your
898c SI Combo or 998c SI Combo will default to the SI Range setting. For
example, if you set the Max Depth to 50 feet and then set the SI Range to
150 feet, your unit will acquire bottom readings from 150 feet (see Side
Imaging® X-Press™ Menu: SI Range).

(Advanced)
Settings: Off, Low, Medium, High 1, High 2, High 3;
Default = Low

Noise Filter adjusts the sonar Noise Filter to limit interference on the display
from sources such as your boat engine, turbulence, or other sonar devices.
The Off setting removes all filtering. Low, Medium, and High 1, High 2, High
3 settings add progressive filtering of the sonar returns. High 1, High 2, and
High 3 are useful when there is excessive trolling motor noise, but in some
deep water situations, the High settings may actually hinder your unit’s
ability to find the bottom.

Water Type
(Advanced)
Settings: Fresh, Salt (shallow), Salt (deep);
Default = Fresh

Water Type configures your unit for operation in fresh or salt water. In salt
water, you can also choose the shallow or deep setting.

Max Depth
(Advanced)
Settings: Auto, 10 to 1500 feet; 3 to 500 meters
[International models only], Default = Auto

Water Type affects the accuracy of deep water depth readings. In salt water,
what would be considered a large fish might be 2 to 10 times bigger than a
large fish in fresh water (depending on the type of fish you are seeking). The
salt water setting allows for a greater range in fish size adjustment to
account for this difference.

Max Depth controls the maximum depth of operation. When Max Depth is
set to Auto, the Fishing System will acquire bottom readings as needed
(within the capacity of the unit). When Max Depth is set to match your
fishing maximum depth, your Fishing System will not attempt to acquire
sonar data below that depth, so more detail will be shown on the screen.
NOTE: If the bottom is deeper than the Max Depth setting, the digital depth
readout will flash, indicating that the Fishfinder cannot locate the bottom.

Troubleshooting

Fishing System Defaults to Simulator
with a Transducer Attached

Before contacting the Humminbird® Customer Resource Center, please read
the following section. Taking the time to review these troubleshooting
guidelines may allow you to solve a performance problem yourself, and
therefore avoid sending your unit back for repair.

A connected and functioning transducer will cause the newly-started
Fishing System to go into Normal operating mode automatically. If, when
you power up the Fishing System, it goes into Simulator mode automatically,
even though a transducer is already connected, this means that the control
head is not detecting the transducer. Perform the following troubleshooting
tasks:

Fishing System Doesn’t Power Up
If your Fishing System doesn’t power up, use the Installation Guide that also
comes with it for specific confirmation details, making sure that:

• Using the Installation Guide that also comes with your Fishing
System, check to make sure that the transducer cable is securely
connected to the Fishing System. Reconnect if necessary, and power
up the Fishing System again to see if this fixes the problem.

• the power cable is properly connected to the control head,
• the power cable is wired correctly, with red to positive battery
terminal and black to negative terminal or ground

• Replace the non-functioning transducer with a known good
transducer if available and power up the control head again.

• the fuse is operational

• Check the transducer cable. Replace the transducer if the cable is
damaged or corroded.

• the battery voltage of the power connector is at least 10 Volts.
Correct any known problems, including removing corrosion from the battery
terminals or wiring, or actually replacing the battery if necessary.

Troubleshooting

110

Display Problems
There are several main conditions or sources of possible interference that may cause problems with the quality of the information displayed on the control head.
Look in the following table for some symptoms of display problems and possible solutions:

Problem

Possible Cause

The control head loses power at high
speeds.

If the power output of your boat’s engine is unregulated, the control head may be protecting itself using
its over-voltage protection feature. Make sure the input voltage does not exceed 20 Volts.

When the boat moves at higher speeds,
the bottom disappears or suddenly
weakens, or the display contains gaps.

The transducer position may need to be adjusted. A mix of air and water flowing around the transducer
(cavitation) may be interfering with the interpretation of sonar data. See your Installation Guide for
suggestions on adjusting the transducer position.
Electrical noise from the boat’s engine may be interfering with sonar reception. See Finding the Cause
of Noise for more information.

There are no fish detected, even when
you know they are in the water under
the boat, or sonar readings seem weak
or faulty.

Sonar readings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle,
not straight down), or there is some kind of mechanical interference, either because it is mounted inside
a hull that is too thick for proper sonar transmission, the bond between the transducer and the hull is
not airtight, or because the transducer is dirty. Check with your Installation Guide for guidance on repositioning the transducer, and make sure the transducer is clean.
Low battery voltage may be affecting the power of signal transmission.
Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause
of Noise for more information.

111

Troubleshooting

Finding the Cause of Noise
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause
noise or interference:

Possible Source of Noise

Isolation

Other electronic devices

Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time
to see if the noise re-appears.

The boat’s engine

To determine whether the boat’s engine is the source of the noise, increase the RPMs while the boat
is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev
the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark
plugs with resistor plugs, install an alternator filter, or route the control head power and transducer
cables away from the engine wiring.

Cavitation from the boat’s propeller

Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15”
(38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.

Sonar Terms

Beam (Sonar Beam) The wide, cone-shaped projection of sound waves formed
as sound travels underwater. See Cone Angle.

Display, FSTN (Film Super-Twist Nematic) FSTN is a monochrome display
technology characterized by black, high-contrast pixels. All monochrome fixed mount
Humminbird® products use FSTN technology.

Bottom Contour The profile of the bottom graphed to the display as the depth

Frequency A measure of the number of sound wave cycles per second of a sound

changes.

impulse transmitted underwater. A typical frequency for fishfinders is 200 kHz, which
offers a good balance of performance under many conditions. Lower frequencies, such
as 50 kHz, are capable of penetrating to greater depths, but with less resolution.
Higher frequencies, such as 455 kHz, offer greater resolution, but are limited in depth
performance. Humminbird® uses a variety of frequencies that are optimized for specific
applications.

Bottom Hardness The density (or composition) of the bottom. Varying levels of
hardness can be determined by interpreting the “thickness“ of the main sonar return.
Hard returns appear thin and black, softer returns appear thicker and less black. It is
important to note that a sonar return from a sloping bottom can have the appearance
of a softer bottom.

Cavitation The effect of air bubbles created as the propeller rotates and the boat
moves through the water.

Grayscale The use of varying shades of gray to represent the strength of the sonar
signal on the display. Traditionally, the strongest sonar signals are represented in
black, and progressively weaker signals are represented in progressively lighter shades
of gray.

Cone Angle The angular measurement of the sonar beam at a specific dB down
point (i.e. -10 dB). See dB Down Point.

Noise The unintentional, external sound waves that interfere with the optimal
operation of sonar. Noise appears as random “dots“ on the display and is caused by a
variety of sources. Many Humminbird® products have a Noise Filter menu setting that
allows the user to clear the screen of noise that is difficult to eliminate (also, see
Troubleshooting).

Dead Zone The area of the sonar beam that receives the sonar signal after the main
bottom return. Fish and other objects close to the bottom that fall within the dead zone
will probably not be visible in the sonar beam. Precision sonar beams, such as the
Humminbird® 20° beam, have a smaller dead zone than wider sonar beams.

Decibel The measurement for sound pressure level, or “intensity”of the sonar return.
See dB Down Point.

Pixels The “picture elements“, or small square blocks, that make up the image on the
LCD. Measured as a vertical by horizontal number (i.e. 640V x 320H), this key
specification typically indicates the quality of resolution. In fishfinders, the total
resolution (vertical multiplied by horizontal) is often less important than the “Vertical
Pixel“ resolution because a greater number of vertical pixels provide finer resolution of
targets detected by sonar. Sonar information on the horizontal axis can vary greatly,
depending on boat speed and the Chart Speed setting.

dB Down Point The standard decibel level at which the sonar cone angle is
measured, and is written as “@ -10 dB” or “@ -3 dB“. Measurements at smaller down
points (bigger negative numbers) indicate that the less intensive sonar signals are
being used for the measurement.

Power Output The amount of sound energy emitted into the water by the

Sonar Update Rate The number of times per second that the transducer’s

transducer’s transmitter. Power output is measured using either RMS (Root Mean
Square) or P-T-P (Peak-to-Peak) measurement systems. Either method is acceptable,
but it is important when comparing power outputs, to make sure that the same
measurement system is being used for both outputs, because P-T-P numbers are 8
times higher than RMS numbers. Greater power output allows the sonar signal to
penetrate through weeds and thermoclines, reach deeper depths and operate more
effectively in noisy environments, such as when the boat is running at high speed.

transmitter/receiver sends and receives sonar signals. A very fast sonar update rate
collects more information and provides a more detailed image of the bottom, fish, and
structure. Many Humminbird® units operate at up to 40 times per second when in
single frequency operation. Due to the limitation of the speed of sound in water, the
update rate begins to slow as depth increases to deeper than 50 feet. In very shallow
water (less than 10 feet), however, update rates as much as 60 times per second can
be achieved.

Pulse Width (Pulse Length) The length of time that a sonar sound burst is

Speed The rate at which the boat moves through the water. Boat speed can be
measured as Speed Over Ground or Speed Through Water. Speed Over Ground is
provided by GPS, and is the measurement of the boats progress across a given
distance. Speed Through Water is provided by a speed paddlewheel, and is the
measurement of the flow past the boat, which may vary depending on current speed
and direction. Speed Through Water is most critical for anglers using downriggers, as
it impacts the running depth of the down riggers. Speed Over Ground is optimal for
navigation, as accurate destination times can be derived from this measurement.
Humminbird® products allow for input and display of both sources.

transmitted into the water. Shorter pulse widths provide better target separation, but
cannot travel to great depths. Longer pulse widths provide better depth penetration,
but result in poorer target separation. Humminbird® varies pulse width based on depth
to optimize both target separation and depth performance. See Target Separation.

Second Return Describes the appearance of a second sonar return below the
primary sonar return (bottom contour) at exactly twice the true depth. The second
return is caused by the same sonar energy bouncing off the bottom once, rebounding
to the water surface and then traveling back down to the bottom to be reflected again.
Second returns are more common in shallow water and over hard bottoms; it is
possible to see a third sonar return under some circumstances. The second return
provides useful information to help determine bottom hardness, as areas with harder
bottoms will generally create a second return. The second return can be used as a
guide to set Sensitivity when in shallower water.

Structure A general term for objects on the bottom that present a discontinuity and
are a likely attractor for fish. This includes bottom contour features (drop-offs, humps,
and holes), standing structure (stumps, timbers, brush piles), and a wide range of
other potential objects (sunken boats, reefs).
Surface Clutter A phenomenon where sonar returns are reflected off of tiny objects
near the surface of the water, including algae and even air bubbles. Typically, saltwater
environments have significantly greater surface clutter than freshwater due to
continuous wind and wave action that causes aeration at the surface.

SONAR (SOund and NAvigation Ranging) Sonar technology uses precision sound
bursts transmitted underwater to determine the distance and other attributes of objects
in the water. Distance can be determined because the speed of sound in water is
constant, and the time for the signal to return is measured. Sound also travels very
quickly underwater, making sonar a responsive, cost-effective tool. Sonar is the basic
technology behind all recreational and commercial fishfinding and depthfinding devices.

Target Separation The measurement of minimum distance that a fishfinder needs to
be able to recognize two very close objects as two distinct targets (i.e. two fish
hanging very close, or a fish hanging very close to structure). Humminbird® fishfinders

provide a very good 2 1/2 inches of target separation in shallower than 100 feet of
depth. Target separation decreases as depth increases due to the need for longer Pulse
Width to achieve greater depth. See Pulse Width.

Acquisition Time The length of time that a GPS receiver typically takes to determine
a position from at least three satellites. Humminbird® GPS receivers provide very fast
acquisition times (under one minute), permitting users to get out on the water faster.

Thermoclines Water layer(s) of distinctly different temperatures that create a sonar

Altitude The height measurement above sea level. Altitude is a measurement that
can be provided by GPS.

reflection due to the density of the differing water temperatures. Typically a
thermocline will appear as a continuous band across the display at some distance
above the bottom contour. Thermoclines are of interest to anglers because fish will
suspend above or below the thermocline as they seek the optimum temperature and
oxygen levels.

Bearing (BRG) The direction to a destination waypoint measured in degrees from
North (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is West).
Chartplotter A navigation device that shows Present Position on a Map, along with
Tracks, Waypoints, and Routes. All Chartplotters are also considered Trackplotters.

Time Variable Gain (TVG) A processing step applied to the sonar return to

Cold Start The procedure that a GPS receiver must perform when it does not have
historical information regarding its current location. This procedure typically lasts for
several minutes, and may be experienced upon first power up of the receiver, or if the
receiver has been moved a great distance.

“normalize“ the data so that objects of equal size (i.e. fish) appear to be the same size,
even if they are separated by a good distance.

Transducer The transducer is part of the sonar system, which mounts on the boat
and is in contact with the water, that converts the electrical energy from the
transmitter into sound energy, and that forms the sonar beam in turn. Internally, the
transducer consists of one or more piezo electric disks that expand by very minute
amounts to create the sound wave. This element also works in reverse, converting the
returned sound energy back into an electrical signal that the receiver interprets. See
SONAR.

Course Over Ground (COG) The current direction the boat is traveling measured in
degrees from North (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is
West). When the Course Over Ground is equal to Bearing, the boat is said to be “On
Course” and will arrive at the destination in the most efficient manner. COG is often
confused with Heading. See Heading.

Zoom A feature that focuses on a smaller area of the bottom to provide enhanced

Cross Track Error (XTE) The straight-line distance of the boat from the intended

resolution. With enhanced resolution, the angler can more easily see fish hanging in
structure or multiple fish hanging close together.

Track. XTE measures how far the boat is off course and also triggers the Off Course
Alarm. See Track.

Differential GPS (DGPS) A system used to improve the position accuracy of the

just above the bottom to provide enhanced resolution. Unlike regular zoom, it
continuously graphs the bottom at a constant point on the display regardless of
changes in depth. This “flattens“ out the bottom contour, but is effective at showing
fish on or near the bottom, and is preferred by many saltwater anglers.

To Go. See Time to Go and Speed Over Ground.

North, Magnetic The principle reference point of the compass (i.e. North is 000°).
Magnetic North relies on the earth’s magnetic field to align a metal pointer generally
towards True North. However, due to local variations in the earth’s magnetic field
around the globe, the difference between True North and Magnetic North can be
greater than 10°. See True North.

Estimated Position Error (EPE) A calculation that indicates the potential position
inaccuracy the user may experience due to a variety of GPS factors which include
satellite position in the sky, signal strength, and others factors.
Fix Type Indicates whether the GPS receiver is providing 2D fix or 3D fix. A 2D fix
requires only three satellites and provides only latitude and longitude. A 3D fix requires
four or more satellites, and provides latitude, longitude, and altitude.

North, True The principle reference point of the compass (i.e. North is 000°). True
North uses the axis of the rotation of the earth as the reference for North and is
constant for all points on the earth. Most GPS units default to True North as the
setting. The GPS heading may vary from the boat compass heading because the
compass uses Magnetic North. See Magnetic North.

GPS (Global Positioning System) GPS provides accurate position (latitude,
longitude, altitude) information virtually anywhere on the earth through satellite
technology and personal receivers on the ground. See How GPS Works.

Present Position The current location (latitude, longitude) determined by GPS. The
Present Position is indicated on-screen by a directional boat icon if the boat is moving
or a round symbol if the boat is stationary.

Heading The direction the boat is pointing and is measured in degrees (i.e. 321°,

Route A series of waypoints linked together in a specific sequence to define a
navigation path between two points, and saved in the fishfinder’s memory. Routes are
often used when frequently traveling between two or more locations because it is a
faster and more accurate method than repeatedly selecting individual waypoints each
time one travels through the same area. Routes consist of a Start Waypoint, an End
Waypoint, and a series of waypoints in between. Users can begin navigation at the
beginning, the end (to run the route in reverse) or at any waypoint in between. See
Waypoint.

where 000° is North, 090° East, 180° is South, 270° is West). Due to wind and waves,
the boat is often traveling in a slightly different direction than it is heading, and
therefore Heading is often confused with Course Over Ground. See Course Over
Ground.

Map Datum Refers to a particular survey of the earth’s surface that was referenced
when creating a chart (i.e. WGS84). It is important to select the correct Map Datum
setting in your fishfinder when comparing GPS position to a paper chart to avoid slight
position inaccuracies. Almost all electronic charts use the WGS84 Map Datum and
therefore, they do not require setting changes.

SD (Secure Digital) An SD card is virtually identical in function to an MMC;
however, the speed at which information can be accessed is generally faster, the
storage capacity is generally larger, and the card has security features which can be
used to prevent extracting the data from the card. SD is the same format that many
digital cameras use. See MMC.

MMC (Multi Media Card) An MMC is a postage stamp-sized memory device used
to store electronic data such a maps, waypoints, routes, and other information. MMC

Selective Availability (SA) A GPS system “feature” that can be implemented by
the U.S. Department of Defense (DoD) to degrade the accuracy of GPS positioning
information. With SA active, the GPS is accurate to within 100 meters 95% of the time.
With SA inactive, the GPS is accurate to within 45 meters 95% of the time. Currently,
SA is inactive and the consumer can enjoy the greater precision GPS provides;
however, the DoD reserves the right to activate SA at any time.

Trackplotter A navigation device that shows Present Position, along with Track,
Waypoint, and Routes, but NO MAP in the background. See Chartplotter.
Trolling Grid A Humminbird® feature that displays a precise reference grid around a
waypoint. This grid is used as a guide pattern for trolling around a specific area to
assure a more efficient and complete coverage of that area.
UTC (Universal Time Constant) UTC is the “standard time” used in navigation and
is the local time in Greenwich England. (UTC is equivalent to Greenwich Mean Time
(GMT)).

Speed Over Ground (SOG) The measurement of the boat’s progress across a given
distance and the speed measurement provided by GPS. An alternate, Speed Through
Water, is provided by a speed paddlewheel, and is the measurement of the flow past
the boat, which may vary depending on current speed and direction. Speed Over
Ground is optimal for navigation because accurate destination times can be derived
from this measurement. Humminbird® products allow for input and display of both
speed measurements.

WAAS (Wide Area Augmentation System) WAAS is complementary technology
to GPS that provides enhanced accuracy through correction signals broadcast from
Federal Aviation Administration WAAS satellites stationed over the USA. These
secondary signals are automatically received by the standard Humminbird® GPS
Receiver. With WAAS signal, GPS accuracy is improved to within 3 meters 95% of the
time. Outside the United States, regional governmental coalitions have created similar
systems such as EGNOS (Europe) and MSAS (Japan).

Time To Go (TTG) The estimated time required to reach the destination waypoint.
TTG is calculated using the SOG and DTG. See SOG and DTG.
Track A series of saved points that define the past path of the boat. These Track

Waypoint The saved location (latitude, longitude) of a point of interest that is stored
in a GPS receiver’s memory. This can include a marker buoy, dock, fishing hole, or
anywhere else the user may want to return to. Humminbird® products offer the ability
to name and assign a symbol to the saved location. Depth, Date, and Time of Day when
the waypoint was created is also saved.

Points are saved at regular time intervals. Tracks are a useful and quick method to see
where you’ve been, and an easy guide to follow to get you back to the starting point.
Generally, all GPS units have a limited number of Track Points that can be saved before
the unit runs out of memory and begins erasing the first track points saved. Because
of this, the user can adjust the Track Point Interval menu to increase the amount of
time between when points are saved, and thus extend the distance covered by a track.
Tracks can also be permanently saved to memory and re-displayed at the user’s option.

Waypoint Target A Humminbird® feature that displays a precise “bull’s eye” around
a selected waypoint. This bull’s eye is used to easily monitor boat position relative to
a waypoint, and is useful for fishing over submerged structure. With Waypoint Targets,
a quick look at the screen lets you know how far off the waypoint the boat has drifted.

Track Line (TRK) The planned line of travel between two waypoints, and it
represents the most efficient path between the two points because it is a straight line.
The TRK is measured in degrees (i.e. 321°, where 000° is North, 090° East, 180° is
South, 270° is West). See Cross Track Error and Course Over Ground.
