ACCESSORIES

Humminbird offers a wide assortment of accessories that complement and

expand the capability of your new fishfinder. These accessories are designed

with the same high standards and are backed by the same one-year warranty.

The Humminbird Accessory catalog included with your unit contains descriptions

of the many accessories available and ordering information. All Humminbird

accessories are available through your full-service Humminbird dealer or factory

direct through our number listed in the Customer Support section.

INSTALLATION OVERVIEW

Your Humminbird fishfinder consists of two primary components to install: the

control head and the transducer.

The control head contains the sonar transmit and receive circuitry, as well as the

user controls and display. It should be installed in a location that provides access

to the controls and visibility while in use. The control head mounts on a quick

disconnect mounting system that swivels and tilts providing flexibility for viewing

from almost anywhere on the boat.

The transducer converts electrical energy from the transmitter into mechanical

pulses or sound waves. The transducer also receives the reflected sound waves

and converts them back into electrical signals for display on the control head. It

should be installed in contact with the surface of the water in an area that has

smooth waterflow- usually on the transom of the boat. There are several

mounting options for the transducer. Review the following section to determine

the method that works for you and your boat.

INSTALLATION PREPARATION

INSTALLATION OVERVIEW

Determining How to Mount the Transducer

Your Humminbird fishfinder includes a standard

transducer. This transducer can be mounted on the

transom of the boat or bonded to the inside of a fiberglass

hull boat.

The transom installation, which is the most widely used,

places the transducer on the outside of the boat hull. This

technique produces the least signal loss, and provides a

way to adjust the transducer after installation. The

mounting hardware included is designed to protect both

the boat and the transducer should the boat strike debris in

the water or when trailering.

As an alternative to transom mounting, it is possible on

many fiberglass-hulled boats to glue the transducer on

the inside of the boat hull. Since fiberglass has similar

sonar characteristics as water, the sonar signal can

pass through the boat hull with minimal loss. The hull

of the boat must be single layer construction (not

double-hulled) Also, any air trapped in the lamination

of the fiberglass would prevent the sonar signal from

passing through.

Inside the hull installations require no holes be drilled

into the boat and through experimentation, high-speed

operation comparable to transom mounting can be achieved. Two-part slow cure

epoxy (not included) is required to glue the transducer in place.

INSTALLATION PREPARATION

ALTERNATE MOUNTING METHODS

ALTERNATE TRANSDUCERS AND MOUNTING METHODS

Your Humminbird fishfinder comes with everything necessary for installation and

operation on most boats. However, there are several situations which may

require a different type of transducer. Inboard boats, wood or metal hulls, and sail

boats create unique transducer mounting needs Alternate transducers and

mounting methods are detailed below.

Portable Mounting

The standard transducer can be adapted for portable

installations with a portable mounting kit available from

Humminbird. This accessory adapts your transducer to a

suction cup mount for temporary installation on the boat hull

or other surface.

Trolling Motor Mounting

The standard transducer can also be adapted to mount on

most trolling motors using a different accessory kit. This

accessory includes a bracket and hose clamp that allows

mounting the transducer to the body of most trolling motors.

Thru-Hull Mounting

Thru-hull transducers install through a hole drilled in the hull

of the boat. Larger boats or boats with inboard motors create

turbulence that make transom mounting ineffective. Also,

hulls that are very thick or are double layered, or made from

materials such as wood or metal, (which do not conduct

sonar signals) make inside the hull mounting inadvisable.

Thru-hull mounting may require the use of a fairing block to level the transducer

with the waterline. Also, since special tools and knowledge may be required to

perform this type of installation, it is best to refer to a qualified marine technician.

INSTALLATION PREPARATION

TRANSDUCER EXCHANGE

TRANSDUCER EXCHANGE

Other transducers are available as replacements for the standard transducer.

You may exchange your new and unassembled transducer for another type by

returning it to the address listed in Customer Support. Some transducers may

have additional cost. Refer to the Accessory catalog or call Customer Support for

information.

BEGINNING INSTALLATION

Now that you have determined the transducer mounting method you can begin

installation of your new Humminbird fishfinder. The installation guide included on

the next few pages provides detailed step by step instructions for installation of

the control head and transducer. For transom mount transducer installations you

will need the mounting template included with your manual.

In addition to the parts included you need the following for installation and

operation:

• A powered hand drill and various drill bits

• Philips and flat-head screwdrivers

• A ruler or measuring tape

• Pen or pencil

• 12 volt power source (your boat’s battery)

• A 1-amp fuse

• A fuse holder (if you are wiring directly to the boat’s battery)

• Silicone sealant (for sealing drilled holes)

• 2-part, slow-cure epoxy (for inside the hull transducer installations)

INSTALLATION

TRANSOM INSTALLATION

Do not begin this transducer installation until you read the Installation

Preparation in the Operation Guide. This chapter contains information

critical to the correct installation of your transducer.

Due to the wide variety of boat hulls, only general instructions are

presented in the installation guide. Each boat hull represents a unique set

of requirements that should be evaluated prior to installation.

TRANSOM INSTALLATION

Step One - Determine Where to Mount the Transducer

Begin the transducer installation by determining where on the

transom to install the transducer. Consider the following to find

the best location:

• It is very important to locate the transducer in an area which is

relatively free of turbulent water, As a boat moves through the

water, turbulence is generated by the weight of the boat, and

the thrust of the propeller(s). This turbulent water is normally

confined to areas immediately aft of ribs, strakes or rows of

rivets on the bottom of the boat, and in the immediate area of

the propeller(s) (Figure 1). On outboard or inboard/outboard

boats it is best to stay at least 15” (40cm) to the side of the

propeller(s).

• If possible, viewing the transom of the boat while the boat is

moving will provide the best means of locating turbulence free

water. If maximum high-speed operation is a high priority, this

is the recommended method. If this is not possible, select a

location on the transom where the hull forward of this location

is smooth, flat, and free of protrusions or ribs.

• The transducer when mounted should point straight down.

The design of the transducer will accommodate a wide range

of deadrises and remain ported straight down (Figure 2).

• On boats with stepped hulls, it may be possible to mount the transducer on

the step. Never mount the transducer on the transom behind a step, as this

area of the transom will not be in contact with the water at high speed (Figure

3).

INSTALLATION

TRANSOM INSTALLATION

• If the propeller(s) is (are) forward of the transom, it may be impossible to find

an area clear from turbulence, and a different mounting technique or

transducer type should be considered.

Step Two - Drill the Mounting Holes

1. Remove the mounting template from the front of the Operations Manual.

2. Hold the template on the transom of the boat in the location where the

transducer will be installed (Figure 4). Align the template vertically, ensuring

the lower edge of the transom meets with the bottom corner

of the template.

3. Using a pencil or punch, mark the two mounting holes

shown on the template onto the transom. Do not mark or

drill any other holes at this time.

4. Using a 5/32” (4mm) bit drill the two holes to a depth of

approximately 1" (3cm). On fiberglass hulls, it is best to

start with a smaller bit and use progressively larger drill bits

to reduce the chance of chipping or flaking the outer

coating.

Step Three - Assemble the Transducer

1. Attach the Pivot to the transducer body as shown in Figure

5, using the #8 – 3/8” (9mm) long allen headed pivot screw,

the headed pin, the two flat washers, and the two toothed

lock washers.

Note: The toothed lock washers must be positioned

between the transducer and the pivot ears. The flat

washers must be positioned to the outside at the pivot

ears.

2. Using the AIlen wrenches provided, loosely tighten the pivot

screw (Figure 6). Do not completely tighten the assembly at

this time, so the pivot angle can be adjusted later.

3. Insert the pivot/transducer assembly into the mounting

bracket as shown in Figure 7. Do not snap the assembly

closed.

INSTALLATION

TRANSOM INSTALLATION

Step Four - Mount the Transducer to the Transom

1. Apply silicone sealant to the mounting holes drilled into the transom.

2. Align the transducer assembly with the drilled holes in the transom (Figure 8).

3. Use either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm)

socket to mount the assembly. Using the two #10 – 1”

(25mm) long slotted hex head screws, mount the transducer

assembly to the transom as shown. Do not fully tighten the

mounting screws in order to vertically adjust the transducer.

Snap the pivot down into place.

Step Five - Adjust the Running Position of the Transducer

The bracket allows height and tilt adjustment, the pivot screws

allow angular adjustment. Initially, adjust the transducer as

described in the following paragraphs. Further adjustment may

be necessary to refine the instillation after high speed testing.

1. First adjust the pivot angle of the transducer body so its

length is parallel with the length of hull of the boat. Then

pivot the transducer down so the rear is about 1/4 inch

(6mm) lower than the front (Figure 9).

2. Fully tighten the two pivot screws using the Allen wrenches.

It may be necessary to retighten the pivot screws after the

initial use as the plastics may still be seating to the lock

washers.

3. Adjust the height of the assembly so the face of the

transducer is 3/16" (4.5mm) beneath the lower edge of the

transom (Figure 10). Mark the position of the mounting

bracket on the transom with a pencil.

4. Force the pivot to the up position to gain access to the

mounting screws. Assure the transducer location has not

changed, then fully tighten the two mounting screws (Figure

11). Snap the pivot back down.

Confirm the pivot angle has not changed.

Note: A third screw location is provided for the

mounting bracket. Drill this hole and install the screw after final testing and

adjustments have been completed.

INSTALLATION

TRANSOM INSTALLATION

Step Six - Route the Cable

There are several ways to route the transducer cable to the to the area where the

control head will be installed. The most common procedure routes the cable

through the transom into the boat.

Inside the boat there is often a channel or conduit used for other

wiring that the cable can be routed along. Do not cut or shorten

the transducer cable and try not to damage the cable insulation.

Route the cable as far as practical from the VHF radio antenna

cables or tachometer cable to reduce the possibility of

interference.

If the cable is too short, extension cables are available to extend

the transducer cable up to a total of 50' (15 m). Call Humminbird

Customer Support for more information.

Follow these steps to route the cable through the transom:

1. Drill a 5/8” (16mm) hole above the water line. Route the

cable through the hole.

2. Fill the hole with silicone sealant.

3. Place the escutcheon plate over the hole and attach with the two #8 x 5/8”

(16mm) screws.

4. Secure the cable by attaching the cable camp to the transom using a #8 x

5/8” (16mm) screw.

Note: The transducer will pivot up to 90 degrees in the bracket. Allow

enough slack in the cable for this movement. It is best to route the cable to

the side of the transducer so the cable will not be damaged by the

transducer during movement.

INSTALLATION

INSIDE THE HULL INSTALLATION

INSIDE THE HULL INSTALLATION

Inside the hull installation requires the mount system and control

head be installed and operational. See Installing the Control Head

for instruction on installing the unit.

Inside the hull mounting generally produces good results in single

thickness fiberglass-hulled boats. Humminbird cannot guarantee

depth performance when transmitting and receiving through the

hull of the boat since some signal loss occurs. The amount of loss

depends on hull construction and thickness, and the installation.

This installation requires slow-cure two-part epoxy. Do not use

silicone or any other soft adhesive to install the transducer, as this

material reduces the sensitivity of the unit. Five minute epoxy has

a tendency to cure before all the air bubbles can be purged.

Step One - Determine the Mounting Location

Begin the transducer installation by determining where inside the

hull to install the transducer. Consider the following to find the

best location:

• Observe the outside of the boat hull to find the areas that are

mostly free from turbulent water. Avoid ribs, strakes, and other

protrusions as these create turbulence (Figure 14).

• As a general rule, the faster the boat can travel the further aft

and closer to the centerline of the hull the transducer has to be

located to remain in contact with the water at high speeds.

Step Two - Test the Mounting Location

There is no opportunity for adjustment after the transducer glued

in place. Therefore, it is best to perform a trial installation on inside the hull

transducers first, and run the boat at high speeds to determine the best mounting

area.

1. At the identified mounting location, lay the transducer body face down with

the pointed end towards the bow.

2. Fill the hull with enough water to submerge the transducer body. Use a sand

filled bag or other heavy object to hold the transducer in position.

The transducer cannot transmit through air. The water purges any air from

between the transducer and the hull and fills any voids in the coarse

fiberglass surface.

INSTALLATION

INSIDE THE HULL INSTALLATION

3. Power up the Control Head.

4. Run the boat at various speeds and water depths while observing the screen

on the Control Head. If the unit functions well at low speeds but begins to skip

or miss the bottom at higher speeds, the transducer needs to be moved. If

depth performance is required, test the fishfinder in water at the desired

depth. Test different locations in the hull until the optimum performance is

achieved.

Step Three - Permanently Mount the Transducer

1. Once the mounting location is determined, mark the position of the

transducer.

2. Remove the water from inside the hull and thoroughly dry the

mounting surface. If the surface is excessively rough, it may be

necessary to sand the area to provide a smooth mounting

surface.

Ensure the mounting area is clear and dry.

3. Mix an ample quantity of two-part slow-cure epoxy slowly and

thoroughly. Avoid trapping air bubbles.

4. Coat the face of the transducer and the inside of the hull (Figure

16).

5. Press the transducer into place with a slight twisting motion to

purge any trapped air from underneath, keeping the pointed end

of the transducer body pointed forward (Figure 17).

Note: Proper operation requires the pointed end of the

transducer body to face towards the bow.

6. Weight the transducer so it does not move while the epoxy is curing.

When the epoxy cures, no water is necessary inside the hull. Neither water,

spilled gasoline, or oil will affect the performance of the transducer.

INSTALLATION

CONTROL HEAD INSTALLATION

CONTROL HEAD INSTALLATION

Step One - Determine Where to Mount

Begin the installation by determining where to mount the control head. Consider

the following to determine best location:

• The cables for power, transducer and temp/speed accessories (if applicable)

should be installed first and must reach the mounting location. Extension

cables are available.

• There are two ways to route the cables to the unit: through a

hole in the mounting surface underneath the mounting bracket

or from a hole outside the mounting bracket. Routing the cables

down under the mount provides maximum weather protection;

however this is not always feasible if the area under the

fishfinder is inaccessible. In this case, route the cables through

a hole at another location and cover with the supplied hole

cover.

• The mounting surface should be adequately supported to

protect the fishfinder from excessive wave shock and vibration,

and provide visibility while in operation.

• The mounting area should allow sufficient room for the unit to

pivot and swivel freely, and for easy removal and installation

(Figures 18-19).

Step Two - Connect the Power Cable to the Boat

A 6’ (2m) long power cable is included to supply power to the

fishfinder. You may shorten or lengthen the cable using 18 gauge

multi-stranded copper wire.

CAUTION: Some boats have 24 or 36 volt electric systems. Be

sure your unit is connected to a 12 VDC power supply.

The Power can be connected to the boat's electrical system at two

places: a fuse panel, usually located near the console, or directly to the battery.

If a fuse terminal is available, use crimp-on type electrical connectors (not

included) that match the terminal on the fuse panel. Attach the black wire to

ground, and the red wire to 12 VDC power (Figure 20). Be sure to use a one amp

fuse in the connection. If you must wire the control head directly to a battery, be

sure to install an inline fuse holder

INSTALLATION

CONTROL HEAD INSTALLATION

and one amp fuse (not included) for the protection of the unit (Figure 21).

Humminbird is not responsible for over voltage or over current failures.

In order to minimize the potential for interference with other

marine electronics a separate power source (such as a

second battery) may be necessary.

Step Three - Drill the Mounting Holes

1. Set the mounting bracket in place on the mounting

surface. Mark the four mounting screw locations with a

pencil or punch.

2. Set the mounting bracket aside, and drill the four

mounting screw holes using a 9/64” (3.6mm) bit.

Step Four - Run the Cables

1. If the cables must pass through a hole underneath the

mounting surface, mark and drill a 1” (25mm) hole

centered between the four mounting holes (Figure 22).

Note: if the cables must pass through the mounting

surface at a different location, drill the 1" (25mm) hole at

that location and pass the cables through from

underneath. Also, you must break out the tabs on the

rear of the mounting base using needle nose pliers

(Figures 24-25).

2. Insert all cables through the 1” (25mm) hole from beneath

the mounting surface.

3. Pass the cables through the grommet (if the cable hole is

underneath the mounting bracket) then press the grommet

in place around the cables and into the 1” (25mm) hole.

4. Pass the cables through the mounting base, out the top of

the mounting bracket.

5. Place the mounting bracket on the mounting surface aligned with the drilled

holes. Insert the four flathead wood screws into the mounting holes and

tighten fully (Figure 23).

Optional: If the cables pass outside the mounting bracket, install the hole

cover over the hole and fasten in place using the two #8 x 7/8” (22mm)

wood screws (Figure 24).

INSTALLATION

CONTROL HEAD INSTALLATION

Step Five - Assembling the Connector Holder

1. Insert the cable connectors into the connector holder.

The cable connectors are labeled, and there are

corresponding labels on the connector holder (Figure

26). The slots for the connectors are keyed to prevent

reverse installation, so do not force the connector into

the holder.

2. Carefully pull the excess cable from beneath the -

mounting surface so the connector holder aligns with the

mounting holes on the front of the mounting bracket

(Figure 27).

3. Snap the support plate to the rear of the connector

holder (Figure 28).

4. Insert the connector holder into place and use the two

#6-32 x ¾” (9mm) screws to fasten it to the mounting

bracket (Figure 28).

5. Install the control head by sliding it onto the mounting

bracket until it is fully seated. To remove the unit simply

depress the latch on the rear of the unit and lift (Figure

29).

Your Humminbird is now ready for operation.

INSTALLATION

TEST THE INSTALLATION

TEST THE INSTALLATION

Testing should be performed with the boat in the water, however you can initially

confirm basic operation with the boat trailered.

Press POWER once to turn the unit on. There will be an audible chirp when any

button is pressed to confirm the button press. If the unit does not power-up,

ensure the unit is fully seated on the mount and that power is available.

The first screen provides four options: Start-up, Options, Simulator, and

Diagnostic. A message at the bottom of the screen indicates the transducer

connection. If no transducer is detected (or one is not connected), the message

will indicate this and the unit will go into simulator after the initial screen times

out.

Note: the transducer must be submerged in water for reliable transducer

detection.

If a transducer is detected, the unit will enter “Start Up” or normal operation

unless you choose another option. If you do not press any button before the timer

reaches “0”, the normal operation screen is displayed. If the boat is in water,

sonar data appears.

If the bottom is visible on screen with a digital depth readout, the unit is working

properly. Ensure the boat is in water greater than 2’ but less than the depth

capability of the unit and the transducer is fully submerged. Remember the sonar

signal cannot pass through air.

If the unit is working properly gradually increase the boat speed to test high-

speed performance. If the unit-functions well at low speeds but begins to skip or

miss the bottom at higher speeds, the transducer requires adjustment. Refer to

the appropriate transducer installation section for more detail.

Note: it is often necessary to make several incremental transducer

adjustments before optimum high-speed performance is achieved.

Important: For Transom Mount transducer installations, install the third mounting

screw after the final transducer adjustments.

TESTING THE INSTALLATION

After installation is complete and all connections are made, you are ready to test the installation

prior to actual use. Thorough testing should be performed with the boat in water, however, 'you

can initially confirm basic operation with the boat trailered.

Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed

that confirms the button press. If the unit does not power-up, ensure that the unit is fully seated

on the mount and that power is available.

Momentarily, information will begin to "march" across the screen from right to left. Remember,

that as each column advances on the screen, it contains information gathered from several

transmit and receive cycles. The column of information on the far right side of the screen is the

most current information, or the view directly under your boat. If your boat is moving, an accurate

depiction of the terrain you have just covered is created on-screen.

If the bottom is visible on-screen with a digital depth readout, the unit is working properly. If the

unit powersup but fails to display bottom information, the transducer is not properly connected.

Ensure that the boat is in water greater than 2' but less than 600' deep, and that the transducer is

fully submerged. Remember that the sonar signal cannot pass through air. Refer to the

troubleshooting section of this manual. If the unit is working properly, gradually increase the boat

speed to test high-speed performance. If the unit functions well at low speeds but begins to skip

or miss the bottom at higher speeds, the transducer installation requires adjustment. Refer to the

appropriate transducer installation section for more detail.

NOTE: It is often necessary to make several incremental transducer adjustments before optimum

high-speed performance is achieved.

USING THE WIDE ONE HUNDRED

The Wide One Hundred is simple to use. Simply press the POWER button, and the unit will

automatically locate the bottom, adjust the depth range and sensitivity to an appropriate level,

and draw a picture of the terrain beneath your boat. If POWER is the only button you press, you

will benefit from the advanced automatic bottom tracking capability of the unit. However, if you

choose to experiment with the many features and controls the Wide One Hundred offers, you can

customize the presentation of information to suit your particular needs. The Wide One Hundred

offers a wide variety of settings and types of display, to satisfy any sonar need.

SIMULATOR OPERATION

The Wide One Hundred contains a simulator which allows you to use the unit as if you are on the

water. This simulator is invaluable for learning how to operate the many features of the Wide One

Hundred.

With the unit turned off, press and hold the POWER button until a continuous chirp is heard. This

initiates the simulator operation, and the unit will simulate all functions as if it were actually on the

water.

When in simulator operation, the Wide One Hundred unit responds to control inputs as if it is in

actual operation, so feel free to experiment with the many features and functions to customize the

Wide One Hundred unit for your particular operation.

To exit the simulator, press POWER to turn the unit off.

WHAT YOU SEE ON-SCREEN

The first thing you may notice about the Wide One Hundred is the high-resolution, super

highvisibility LCD screen. This LCD display uses super-twist technology, and is ruggedized for

tough shock and vibration endurance. The display is also backlit for nighttime operation, and uses

special components so it can operate at temperatures more extreme than you are likely to

encounter.

The horizontal line at the top of the display is the "Zero" line. This represents the surface of the

water. The "Zero" line will always have a gap which moves as the screen updates. This gap lets

you know that the display is updating even if the bottom terrain remains the same or is not visible

on the selected depth range. The farthest right column of information is the most recent

information, and it shows what is directly under your boat.

At power-up, the Wide One Hundred locates the bottom and adjusts the depth range to a setting

most appropriate for that depth. The bottom will be usually shown about 2/3 of the way down the

display.

Since some species of fish tend to be better reflector of sonar than others, the strength of return

is not always an accurate indicator of fish size, however, typically, the larger the fish, the larger

the signal return.

CONTROL FUNCTIONS

The Wide One Hundred unit uses only seven buttons to control all functions. The

controls are divided into two groups: POWER, STOP, and LIGHT are one group,

and the Menu System controls are the other group. When any button is pressed, an

audible "chirp" will verify the control input.

POWER, as previously discussed, powers the Wide One Hundred for normal

operation. Also,

if the unit is powered off, press and hold POWER until you hear a continuous "chirp"

to enable simulator operation as discussed in "Simulator Operation". Pressing

POWER when the unit is in normal or simulator operation will power the unit off.

STOP freezes the display to allow closer study. Pressing STOP again will resume

normal operation. Also, if a menu is on-screen, STOP will retain the menu on-

screen until STOP is pressed again.

The transmitted sonar signal travels downward, and is reflected back toward the surface by the

bottom or other objects for display on-screen. If a target is detected between the surface and the

bottom, it is displayed as a fish symbol. Depending on the strength of the signal reflected from the

object, one of three different size symbols is used. These reflected signals are "normalized" for

depth, so that a small fish does not appear to be a large fish if it is close to the boat.

LIGHT enables a two-level display backlight. Pressing once will turn the light on low, pressing a

second time will increase the backlight to the high setting, and pressing a third time will turn the

backlight oft.

The four remaining buttons work together to control the Menu System-an array of menu

controlled functions.

MENU brings a menu on-screen for adjustment, or if a menu is already present, the next menu in

sequence will appear. Menus will go off-screen and normal operation will resume after a short

period of time. If you wish to keep the menu onscreen for an extended period of time, press

STOP.

UP ARROW selects the next larger or next sequential adjustment within the menu. Holding an

Arrow button down will cause the unit to continue to make the adjustment, until a limit is reached,

and a continuous chirp is heard.

DOWN ARROW selects the next smaller adjustment within the menu.

ENTER is used to toggle other menu options on and oft.

All menus use the same general layout as shown in in the sample menu below. The heading of

the menu is at the top. The area in the center is controlled by the UP and DOWN ARROWS, and

the area under the horizontal line is controlled by the ENTER button. Not all menus are affected

by all controls, but the layout is the same regardless.

Pressing MENU repeatedly will sequentially display all available menus.

Menu Functions

The following section explains each menu in detail, and how these adjustments can be used to

extract the maximum information from the sonar returns. Remember, once a setting has been

changed, the Wide One Hundred will remember that setting until it is changed again, or until the

unit is powered off.

Sensitivity

As the Wide One Hundred receives returned signals, the

sensitivity of the receiver is adjusted automatically based on a

number of factors such as the depth of the water, and the

signal clarity. In murky water, full of debris, the Wide One

Hundred will select a lower sensitivity setting. In clear water,

where there is little debris to defract the sonar signal, the

sensitivity is set higher.

The Sensitivity menu allows you to "bias" this automatic setting

up or down based on personal preference. You can select a

bias of +5 to -5, for 11 different bias settings. A bias setting of

"0" has no effect on the automatic function. A +3 setting selects

a sensitivity setting three steps higher than the unit would

normally select, so even the smallest returns are displayed

onscreen.

A setting of -2 sets the sensitivity two steps below what the unit

would normally select, so only the largest targets or other

returns are displayed.

Range

The Wide One Hundred adjusts the depth range automatically,

so the bottom return is displayed at the bottom 1/3 of the

display. This leaves the top 2/3 to display anything between the

surface and the bottom. As your boat moves over deeper or

shallower water, the unit adjusts the depth range of the display

to keep the bottom return in the same general area on the

screen.

You may, however, choose to control this range adjustment

manually. By pressing ENTER, you can select manual

operation, meaning the unit will no longer adjust the depth

range automatically. The depth range selected is controlled by

the UP and DOWN arrow buttons. The depth ranges are 015',

30', 60', 120', 180', 240', 360', 480', & 600'.

If you alter the depth range, Manual operation is automatically selected and the area beneath the

bottom will no longer be blackened-in.

This feature is valuable if you are only interested in targets near the surface. The Wide One

Hundred will always display the digital depth of the water, regardless of whether the bottom is

shown on the selected depth range.

Zoom

Another form of range control is Zoom. The Zoom menu allows three different settings; Zoom Off,

Zoom On, and BL or Bottom Lock. Zoom allows selection of various ranges for full screen

viewing, not necessarily including the surface. By using the display to view a smaller area, the

effective display resolution is increased, and the units ability to separate targets close together is

enhanced.

The zoom range is determined by the depth range in use when zoom is enabled. In shallow

water, when the 15' or 30' depth range is used, the zoom range will be 7-1/2'. If the 60' or 120'

depth range is in use, the zoom range will be 15', if a 180' to 480' depth range is used, the zoom

range will be 30', and if the 600' range is in use, the zoom range will be 60'.

To enable zoom, adjust the depth of the zoom range first using

the UP and DOWN Arrow buttons until the upper and lower limit

numbers correspond with the range you wish to view, then

enable Zoom using the ENTER button.

Once you are in Zoom, you may still adjust the depth of the

zoom range by using the UP and DOWN Arrow buttons. The

Zoom menu will not appear when an adjustment is made unless

MENU is pressed.

The digital depth readout will continue to track the bottom even

when Zoom is enabled.

Bottom Lock is a function of Zoom, except the depth adjustment

is controlled automatically to view the area immediately above

the bottom. This is especially useful if you are looking for

structure or minor variations in terrain in areas of relatively flat

bottom terrain. To enable Bottom Lock, press ENTER until the BL is highlighted. The Zoom range

will be controlled by the current depth range, as in Zoom, and will be indicated on the Zoom

menu.

Bottom Alarm

The Wide One Hundred contains an audible alarm to warn you of shallow water depths. This

alarm is adjustable from 2' to 99' of depth. To enable the alarm, simply adjust the alarm depth

using the UP and DOWN arrow buttons, and press ENTER. Whenever the depth of the water

beneath your boat is equal to or less than the selected alarm depth, a continuous alarm will

sound.

To disable the alarm, either move to deeper water, or select the Bottom Alarm menu, and press

ENTER to turn the alarm off.

Fish Alarm

The Fish Alarm alerts you to the presence of fish, or other

targets not attached to the bottom, in the water beneath your

boat. The Fish Alarm has 3 different settings which correspond

to the 3 different size fish targets shown on-screen.

To enable Fish Alarm, use the UP and DOWN arrow buttons to

adjust the size return you want to be alerted to; large fish only,

large and medium size fish, or all fish. Then press ENTER to

enable the alarm. When Fish Alarm is on, an onscreen indicator

will be shown.

Remember that it is impossible for sonar to determine if a signal

return is a fish or some other type of object or suspended

debris. Any object not connected to the bottom is normally a

fish and is portrayed as a fish symbol. The strength of the

reflected sonar signal from a target is a good indicator of the

size of the target, and the fish symbol displayed represents the

strength of the signal reflected from it.

ID

ID is the automatic identification of target returns based on the strength of the returned signal and

other factors. Three options are available: ID "On" displays targets as one of three different size

fish symbols.

"ID+", the default setting, provides more information about the location of the target by attaching

depth "strings" showing the digital depth of the target. When there are numerous targets on-

screen, not every target depth is shown, to avoid excessive clutter on-screen.

ID "OFF" disables the units interpretation of targets, and displays the "raw" sonar information as it

is received. Advanced users may prefer this type of presentation, so they can make there own

interpretation from the information displayed.

Scroll

Scroll Rate controls the update rate of the display. There are

five rate settings available. You may speed up or slow down the

rate to match your personal preference. To present the most

accurate representation of the terrain beneath your boat, the

scroll rate of the display should be approximately synchronized

to the speed of the boat. If your boat is stationary, or moving

slowly, select a slower scroll rate, and if you typically operate

the boat at high speeds, use a faster scroll rate.
