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
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.
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
