Contact Humminbird

Sonar technology is based on sound waves. The Humminbird FishFinder uses sonar
to locate and define structure, bottom contour and composition, as well as depth
directly below the transducer.
Your FishFinder 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.
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.
Your FishFinder will either have Single Beam sonar or DualBeam sonar. Find the
correct sonar description that applies to your unit.
NOTE: All sonar units typically read to deeper depths in fresh water than in salt water.

Single Beam Sonar
Your Humminbird FishFinder 515, 525 or 535 uses a 200 kHz
single beam sonar system with a 20° area of coverage. Depth
capability is affected by such factors as boat speed, wave
action, bottom hardness, water conditions and transducer
installation.

DualBeam Sonar
NOTE: Entries in this Table of Contents which list (International Only) are only available on
products sold outside of the US and Canada by our authorized International Distributors.
To obtain a list of authorized International Distributors, please visit our website at
www.humminbird.com or contact our Customer Resource Center at 334-687-0503 to
locate the distributor nearest you.
NOTE: Entries in this Table of Contents which list (with Temp/Speed Only) require the
purchase of separate accessories. You can visit our website at www.humminbird.com to
order these accessories online or contact our Customer Resource Center at 1-334-687-0503.
v

Your Humminbird FishFinder 565 uses a 200/83 kHz dual beam
sonar system with a wide (60°) area of coverage. DualBeam
sonar is optimized to show the greatest bottom definition using
a narrow (20°) beam yet can still indicate fish found in the wide
(60°) beam when the Fish ID+TM feature is turned on. DualBeam
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.

Wha t’s On the Scr een
The Humminbird FishFinder can display a variety of useful information about the area

under and adjacent to your boat, including the following items:

Depth - water depth; can be set to alarm when the
water becomes too shallow.

Structure - where fish may be hiding.
Fish - the FishFinder displays fish as arches and/or
fish icons, and can be set to alarm when a fish of a
certain size is detected. When a target is detected, a
Fish ID+TM symbol appears on the display with the
depth displayed above it. The size of the symbol
indicates the intensity of the sonar return. The unit
will clearly show schools of Bait Fish as "clouds" of
different shapes and sizes, depending on the
number of fish and boat speed.

Temperature - water surface temperature.

Timer - Elapsed time with Temp/Speed Accessory.
Distance - Distance traveled with Temp/Speed
Accessory.

200kHz, Narrow Beam Shaded Fish Symbol

Average Speed - Average speed reading with
Temp/Speed Accessory.

83kHz, Wide Beam Hollow Fish Symbol
(Dual Beam Units Only)

Bait Ball

Thermoclines - layers of water with different
temperatures that appear at different depths and
different times of the year. A thermocline typically
appears as a continuous band of many gray levels
moving across the display at the same depth.

Hard Bottom
Rocky Bottom
Second Sonar Return - when the sonar signal
bounces between the bottom and the surface of
the water and back again. Use the appearance of
the second return to determine bottom hardness.
Hard bottoms will show a strong second return,
while soft bottoms will show a very weak one or
none at all.

Soft Bottom

to show the bottom. Depth Range is automatically selected to keep the bottom visible on
the display, although you can adjust it manually as well (see Sonar
X-PressTM Menu). Either five or six additional Digital Readouts (depending on your model)
display information from optional-purchase accessories. These information boxes can be
customized to show only the information desired (see Setup Menu Tab, Select Readouts).

The views available on your FishFinder are:
• Sonar View
• Zoom View
• Big Digits View.
Sonar View is the default view. When the VIEW key is pressed, the display cycles
through the available views. When the EXIT key is pressed, the display cycles
through the available views in reverse order. Any view can be hidden or displayed as
part of the view rotation using Select View from the Advanced Setup Menu.
NOTE: When you change any menu settings that affect the sonar, the view will update
immediately (i.e. you don’t have to exit the menu to apply the change to the screen). For
instance, by switching between "Inverse" and "Structure ID" from the X-PressTM menu it is
possible to quickly alternate between the two viewing methods.

Sonar View
Sonar View presents a historical log of sonar returns. Depth is always displayed.
Readouts for temperature and speed are automatically displayed if the appropriate
accessory is connected. The most recent sonar returns are charted on the right side
of the window; as new information is received, the older information is moved
across the display to the left.

A Digital Depth Readout is displayed in the upper left corner. A scale with Upper and
Lower Depth Range readouts appears along the right edge of the Sonar View. The
scale indicates the distance from the surface of the water to a depth range sufficient

NOTE: If the Depth number is flashing, it means that the unit is having trouble locating
the bottom. This usually happens if the water is too deep, the transducer is out of the
water, the boat is moving too fast, or for any other reason that the unit can’t accurately
receive continuous data.

Understanding Sonar Hist or y
It is important to understand the significance of the Humminbird 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.

Real Time Sonar (RTS®) Window
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.
The Narrow RTS Window
indicates the sonar intensity
through the use of grayscale.
The grayscale used matches
the bottom view grayscale
setting used in the sonar
history window (i.e. Inverse,
StructureID®, WhiteLine®,
Bottom Black). The depth of
the sonar return is indicated
by the vertical placement of
the return on the display
depth scale.

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. The
Wide RTS Window does not
make use of grayscale. (see
Sonar Menu - RTS® Window).

Sonar Z oom View

Big Digits View

Sonar Zoom View increases the displayed resolution to separate sonar returns that
are very close together, such as those caused by fish suspended close to the bottom
or within structure. In Zoom View, the display is split to show a narrow slice of the
full range view on the right and the zoomed view on the left. The full range view on
the right also contains the Zoom Preview Box that shows what part of the full range
view is shown in zoom view on the left; the Zoom Preview Box tracks the bottom in
the full range view.

Big Digits View provides digital data in a large, easy-to-see format. Depth is always
displayed. Readouts for temperature, speed and Triplog information are displayed
automatically if the appropriate accessory is connected to the system. The Triplog
shows distance traveled, average speed, and time elapsed since the Triplog was last
reset. The digital readouts in the Big Digits View cannot be customized.

As the depth changes, the zoomed view updates automatically to display a
magnified image of the bottom. The Zoom Preview Box shows where the zoomed
view is in relation to the full range view. The Zoom Level, or magnification, is
displayed in the lower left corner and can be changed to suit conditions (see Sonar
X-Press Menu: Zoom Level). Upper and Lower Zoom Depth Range numbers indicate
the depth of the water which is being viewed.
Digital depth is displayed in the upper left hand corner. No additional digital
readouts, such as Temperature or Voltage, can be displayed in the Sonar Zoom View.

Bot t om Pr esen ta tion
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.

Structure ID® represents weak returns as light
pixels and strong returns as dark pixels. This has the
benefit of ensuring that strong returns will be
clearly visible on the display.

Bottom Contour Profile with
RTS® Window. Temp/Speed
Accessory is optional.

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.

Hard Bottom
Soft Bottom
Rocky Bottom

The sonar returns from the bottom, structure and fish can be represented as either
Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-Press
Menu: Bottom View for details on how to set the bottom view.
Inverse is a method where weak returns are shown
with dark pixels and strong returns with lighter
pixels. This has the benefit of ensuring that weak
signals will be clearly visible on the display.

Bottom Black displays all pixels below the bottom
contour as black, regardless of signal strength.
This has the benefit of providing a high contrast
between the bottom and other sonar returns on
the display. Any targets such as fish, structure
and thermoclines will be shown using the Structure
ID method.

apply the change to the screen). For instance, by switching between "Inverse" and
"Structure ID" from the X-Press menu it is possible to alternate quickly between the
two viewing methods.

Start-Up Options Menu

See the following paragraphs for more information
about each of these choices.

Normal Oper a tion
Use Normal operation for on the water operation with a transducer connected. In
addition, your FishFinder uses advanced transducer detection methods to
determine if a transducer is connected. If a functioning transducer is connected,
Normal operation will be selected automatically at power up and your FishFinder
can be used on the water.
Exit Normal operation by powering your FishFinder off.

Simula t or
Use the Simulator to learn how to use your FishFinder before taking your boat on
the water. The Simulator is a very powerful tool that simulates on the water
operation, providing a randomly-updated display. We recommend going through
this manual while using the Simulator, since all of the menus function and affect the
display the way they actually do when in Normal operating state.
NOTE: To get the full benefit of the Simulator, it is important to select Simulator manually
from the Start-Up Options menu as opposed to letting the FishFinder enter Simulator
automatically (as it will if a transducer is not connected and you do nothing during power
up). Manually selecting Simulator from the Start-Up Options menu allows you to preconfigure your FishFinder for on the water operation. Any menu changes you make will
be saved for later use.

Sonar X-PressTM Menu

Sensitivity
Sensitivity controls how much detail is shown on the
display. Increasing the sensitivity shows more sonar returns from small baitfish and
suspended debris in the water; however, the display may become too cluttered. 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. If Sensitivity is adjusted
too low, the display may not show many sonar returns that could be fish.

Self Test displays results from the internal diagnostic self test, including unit serial
number, Printed Circuit Board (PCB) serial number, software revision, total hours of
operation and the input voltage.
Accessory Test lists the accessories connected to
the system.
NOTE: The speed accessory will be detected only if the

To adjust the Sensitivity:
1. Highlight Sensitivity on the Sonar X-Press menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the
Sensitivity setting. (Low = 1, High = 20, Default = 10)

Upper R ang e
(Advanc
ed: Sonar and Big Digits Views Only)
(Advanced:
Upper Range sets the shallowest depth range that will be displayed on the Sonar
and Big Digits Views. The Upper Range menu choice is available when User Mode is
set to Advanced (see Setup Menu Tab: User Mode). 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.

To adjust the Upper Range:
1. Make sure you are in Advanced Mode, then highlight Upper Range on the
Sonar X-Press menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the
Upper Range setting. (0 to 790 feet or 0 to 257 meters [International Models
Only], Default = 0)

L ow er R ang e
Lower Range sets the deepest depth range that will be
displayed. Automatic is the default setting. When in automatic mode, the lower
range will be adjusted by the unit to follow the bottom. Selecting a specific setting
locks the depth range into Manual mode. Use both Upper and Lower Range together
to view a specific depth range manually when looking for fish or bottom structure.
M will be displayed in the lower right corner of the screen when you start
manually adjusting the Lower Range to indicate that you are in Manual mode.

To adjust the Lower Range:
1. Highlight Lower Range on the Sonar X-PressTM menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the
Lower Range setting. (AUTO, 10 to 800 feet, 3 to 260 meters [International
Models Only], Default = AUTO)

Char t Speed
Chart Speed determines the speed at which the sonar
information moves across the display, and consequently the amount of detail
shown. A faster speed shows more information in the Sonar View 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. Adjust Chart Speed to your personal preference.
To adjust the Chart Speed:
1. Highlight Chart Speed on the Sonar X-Press menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the
Chart Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest,
Default = 4)

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,
allowing you to see a more detailed view than you would see if the display
went all the way to the bottom.

Bot t om View

Sonar Menu Tab

Bottom View selects the method used to represent
bottom and structure on the display. Inverse represents weak returns as dark pixels and
strong returns as lighter pixels. This has the benefit of ensuring that weak signals will
be clearly visible on the display. Structure ID® represents weak returns as light pixels
and strong returns as dark pixels. This has the benefit of ensuring that strong returns
will be clearly visible on the display. 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. Bottom Black displays all pixels below the bottom contour as
black, regardless of signal strength. Any targets such as fish, structure and thermoclines
will be shown using the Structure ID method. This has the benefit of providing a high
contrast between the bottom and other sonar returns on the display. (See Bottom

(Sonar Zoom
Zoom View Only)
Zoom Level sets the magnification level for the Sonar Zoom View, and is only available
on the X-PressTM menu when the Sonar Zoom View is active. Use Zoom to increase the
display resolution to separate sonar returns that are very close together.
To adjust the Zoom Level:
1. Highlight Zoom Level on the Sonar X-Press menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Zoom Level
setting for the Sonar Zoom View. (2x, 4x, 6x, 8x, Default = 2x)
NOTE: The Zoom Preview Box tracks the bottom and cannot be moved by the user.

Fish ID+TM 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. Single beam sonar
FishFinders represent targets as Shaded Fish Symbols. Dual beam sonar FishFinders
represent targets detected in the 200 kHz narrow beam as Shaded Fish Symbols, and
represent targets detected in the 83 kHz wide beam as Hollow Fish Symbols with their
associated depths. The sonar return for the Hollow Fish Symbols will not be shown.

200kHz, Narrow Beam Shaded Fish Symbols

83kHz, Wide Beam Hollow Fish
Symbols(Dual Beam Only)

When Fish ID+ is turned off, the FishFinder shows only the raw sonar returns on the
display. For dual beam Fishfinders, when Fish ID+ is turned off, only the narrow
beam is used to detect sonar returns. 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.

Real Time Sonar (RTS®) Window
(Sonar View Only)
RTS® Window sets the RTS window to either Wide or Narrow, or turns it off in the
Sonar View. The RTS window always updates at the fastest rate possible and only
displays returns that are within the transducer beam. (See Real Time Sonar (RTS)
Window for additional detail).

Transducer Cone and Fish Arches
RTS Window (Wide)

RTS Window (Narrow)

RTS Window (Off)

To turn Fish ID+ on or off:
1. Highlight Fish ID+ on the Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to turn the Fish ID+ setting

Fish Sensitivity

To change the RTS Window setting:
1. Highlight RTS Window on the Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the RTS Window
setting. (Wide, Narrow, Off, Default = Off)

Fish 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. Fish Sensitivity is used in conjunction
with Fish ID+. Fish ID+ must be On for Fish Sensitivity to affect the ability of the
FishFinder to identify sonar returns as fish.
To change the Fish Sensitivity setting:
1. Highlight Fish Sensitivity on the Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Fish
Sensitivity setting. (Low = 1, High = 10, Default = 5)

Depth Lines
(Advanc
ed)
(Advanced)
Depth Lines divide the display into four equal sections which are separated by three
horizontal depth lines. The depth of each line is displayed along the depth scale. You
can either turn Depth Lines On or Off. The Depth Lines menu choice is available
when User Mode is set to Advanced (see Setup Menu Tab: User Mode).

Sur f ac e Clut t er
(Advanc
ed)
(Advanced)
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. The
Surface Clutter menu choice is available when User Mode is set to Advanced (see
Setup Menu Tab: User Mode).

Surface Clutter

Noise Filt er
(Advanc
ed)
(Advanced)
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 Noise
Filter menu choice is available when User Mode is set to Advanced (see Setup Menu
Tab: User Mode).
NOTE: The Off setting removes all filtering; Low, Medium and High settings add
progressive filtering of the sonar returns. In some deep water situations, the High setting
may actually hinder your FishFinder’s ability to find the bottom.

To change the Noise Filter setting:

Wa t er Type
(Advanc
ed)
(Advanced)
Water Type configures your unit for operation in fresh or salt water. The Water Type menu
choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).
NOTE: 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. Also,
make sure that the Water Type is set accurately, especially in salt water, as this affects the
accuracy of deep water depth readings.

To change the Water Type setting:

1. Make sure you are in Advanced User Mode, then highlight Noise Filter on
the Sonar main menu.

1. Make sure you are in Advanced User Mode, then highlight Water Type on

Max Depth
(Advanc
ed)
(Advanced)
Max Depth adjusts the maximum depth of operation. The performance of your
FishFinder can be tuned to the maximum depth you will be fishing in by setting the
Max Depth. When a maximum depth is set, your FishFinder will not attempt to
acquire sonar data below that depth, thus increasing overall performance. When Max
Depth is set to Auto, the FishFinder will acquire bottom readings as needed (within
the capacity of the unit). If the bottom is deeper than the Max Depth setting, the
digital depth readout will flash, indicating that the FishFinder cannot locate the
bottom. The Max Depth menu choice is available when User Mode is set to Advanced
(see Setup Menu Tab: User Mode).
To change the Max Depth setting:
1. Make sure you are in Advanced User Mode, then highlight Max Depth on
the Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Max Depth
setting. (AUTO, 10 to 800 feet or 3 to 260 meters [International Models
Only], Default = AUTO)

FishFinder Doesn’t Power Up
If your FishFinder doesn’t power up, use the Installation Guide that also comes with
it for specific confirmation details, making sure that:
• the power cable is properly connected to the FishFinder control head,
• the power cable is wired correctly, with red to positive battery terminal and
black to negative terminal or ground
• the fuse is operational
• 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.

FishFinder Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started FishFinder to
go into Normal operating mode automatically. If, when you power up the FishFinder,
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:
• Using the Installation Guide that also comes with your FishFinder, check to
make sure that the transducer cable is securely connected to the FishFinder.
Reconnect if necessary, and power up the FishFinder again to see if this fixes
the problem.
• Replace the transducer with a known good transducer if available and
power up the control head again.
• Check the transducer cable. Replace the transducer if the cable is damaged
or corroded.

Displa y Pr oblems

Finding the C ause of Noise

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:

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:

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.

How to Isolate It

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.

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.

Possible Source of Noise

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 re-positioning
the transducer, and make sure the transducer is clean.
Low battery voltage may be affecting the power of
signal transmission.
Electrical noise from the boat’s engine may be
interfering with sonar reception. See Finding the
Cause of Noise for more information.
