INSTALLATION
MOUNTING
Install the unit in any convenient location, provided there is clearance
behind the unit when it is tilted for the best viewing angle. Holes in the
bracket base allow wood screw or through-bolt mounting. You may need
to place a piece of plywood on the back of thin fiberglass panels to secure
themountinghardware.Makecertainthereisenoughroombehindtheunit
to attach the power and transducer cables.
The gimbal bracket will also accept the GBSA-1 swivel bracket adapter
that lets you rotate the unit a full 360°.
The smallest hole that allows one power or transducer connector to pass
through is 3/4". After the hole is drilled, push the transducer connector up
through the hole first, then drop the power cable down through it.

After the cables have been routed, fill the hole with a good marine sealing
compound. Offset the bracket to cover the hole. Route the power cable
through the slot. Break out one of the holes in the back of the bracket for
the transducer cable.

Transducer Installation
Some of the models covered by this manual have a transom-mount
transducer included. There two different transducers that could be
packed with your unit. One is a 20° cone angle "Skimmer" transducer
that can be mounted on the transom or epoxied inside certain boats to
"shoot-thru" the hull. The other transducer is an 8° cone angle "Skim-
mer" transducer that is transom-mounted only.
The 8° transducer has a “kick-up” mounting bracket helps prevent dam-
age if the transducer strikes an object while the boat is moving. If the
transducer does “kick-up”, the bracket can easily be pushed back in
place without tools.
Read this manual carefully before attempting the installation. Determine
which of the mounting positions is right for your boat. Use extreme care
if mounting the transducer inside the hull, since once it is epoxied into
position, the transducer usually cannot be removed. Remember, the
transducer location is the most critical part of a sonar installation.
Location - General - All Transducers
1. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is to be mounted inside the hull,
then the chosen location must be in the water at all times. If the
transducer is not placed in a smooth flow of water, interference will
show on the sonar’s display in the form of random lines or dots
whenever the boat is moving.
2. The transducer should be installed with it’s face pointing straight
down, if possible.
3. If the transducer is mounted on the transom, make certain it doesn’t
interfere with the trailer or hauling of the boat. Also, don’t mount it
closer than approximately one foot from the engine’s lower unit. This
will prevent cavitation interference with the propeller. Typically, the
transducer should be mounted as deep in the water as possible. This
increases the chance that it will be in the water in high speed and
reduces the possiblity of air bubble interference.
4. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps, and areators
can be displayed on the sonar’s screen. Use caution when routing
the transducer cable around these wires.

Shoot-thru-hull v.s. Transom Mounting
(20° Transducer Only)
Typically, shoot-thru-hull installations give excellent high speed opera-
tion and good to excellent depth capability. There is no possibility of
damage from floating objects. It can't be knocked off when docking or
loading on the trailer.
However, the shoot-thru-hull installation does have its drawbacks. One,
some loss of sensitivity does occur, even on the best hulls. This varies
from hull to hull, even from different installations on the same hull. This
is caused by differences in hull layup and construction. Two, the angle
of the transducer cannot be adjusted for the best fish arches. This can
be a problem on some hulls that sit with the bow high when at rest or at
slow trolling speeds. Follow the procedure listed in the shoot-thru-hull
installation section in this manual to determine if you can satisfactorily
shoot through the hull.
Transducer Assembly and Mounting - 20°Transducer Only
The best way to install this transducer is to loosely assemble all of the
parts first, place the transducer’s bracket against the transom and see if
you can move the transducer so that it’s parallel with the ground.
1. Press the two small plastic ratchets into the sides of the metal bracket
as shown below. Notice there are letters molded into each ratchet.
Place each ratchet into the bracket with the letter “A” aligned with the
dot stamped into the metal bracket.This position sets the transducer’s
coarse angle adjustment for a fourteen (14) degree transom. Most
outboard and stern-drive transoms have a fourteen degree angle.

2. Slide the transducer between the two ratchets. Temporally slide the
bolt though the transducer assembly and hold it against the transom.
Looking at the transducer from the side, check to see if it will adjust so
that its face is parallel to the ground. If it does, then the “A” position is
correct for your hull.If the transducer’s face isn’t parallel with the ground,
remove the transducer and ratchets from the bracket.Place the ratch-
ets into the holes in the bracket with the letter “B” aligned with the dot
stamped in the bracket. Reassemble the transducer and bracket and
place them against the transom. Again, check to see if you can move
the transducer so it’s parallel with the ground. If you can, then go to
step 3.If it doesn’t, repeat step 2, but use a different letter until you can
place the transducer on the transom correctly.
RATCHETS
3. Once you determine the correct position for the ratchets, assemble
the transducer as shown at left. Don't tighten the lock nut at this time.

4. Hold the transducer and bracket assembly against the transom. The
transducer should be roughly parallel to the ground.The bottom of the
transducer bracket should be in line with the bottom of the hull. Don't
let the bracket extend below the hull! Mark the center of the slots for
the mounting holes. Drill two 5/32" holes in the marked locations for
the #10 screws supplied with the transducer.

5. Remove the transducer from the bracket and re-assemble it with the
cable passing through the bracket over the bolt as shown above. At-
tach the transducer to the transom. Slide the transducer up or down
until it’s aligned properly on the transom as shown above.Tighten the
bracket’s mounting screws.Adjust the transducer so that it’s parallel to
the ground and tighten the lock nut until it touches the flat washer, then
add 1/4 turn. Don’t over tighten the lock nut! If you do, the transducer
won’t “kick-up” if it strikes an object in the water.
6. Route the transducer cable to the sonar unit. Make certain to leave
some slack inthe cable at the transducer as shown above. If possible,
route the transducer cable away from other wiring on the boat.Electri-
cal noise from the engine’s wiring, bilge pumps, VHF radio wires and
cables, and aerators can be picked up by the sonar.Use caution when
routing the transducer cable around these wires.
IMPORTANT!
Clamp the transducer cable to the transom close to the transducer.This
can prevent the transducer from entering the boat if it is knocked off at
high speed.
7. Make a test run to determine the results. If the bottom is lost at high
speed, or if noise appears on the display, try sliding the transducer
bracket down. This puts the transducer deeper into the water, hope-
fully below the turbulence causing the noise. Don't allow the trans-
ducer bracket to go below the bottom of the hull!

SHOOT-THRU-HULL
(20° Transducer Only)
The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass
layers. The sonar signal must pass through solid fiberglass. A success-
ful transducer installation can be made on hulls with flotation materials
(such as plywood, balsa wood, or foam) between layers of fiberglass if
the material is removed from the chosen area. For example, some
manufacturers use a layer of fiberglass, then a core of balsa wood,
finishing with an outer layer of fiberglass. Removing the inner layer of
fiberglass and the balsa wood core exposes the outer layer of fiberglass.
The transducer can then be epoxied directly to the outer layer of fiber-
glass. After the epoxy cures, the hull is watertight and structurally sound.
Remember, the sonar signal must pass through solid fiberglass. Any air
bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar
signals.
To choose the proper location for thru-hull mounting, anchor the boat in
60 feet of water. Add a little water to the sump of the boat. Plug the

transducer into the sonar unit, turn it on, then hold the transducer over
the side of the boat. Adjust the sensitivity and range controls until a
second bottom echo is seen on the display. (you will need to turn both
automatic and ASP off.) Don’t touch the controls once they’ve been set.
Next, take the transducer out of the water and place it in the water in the
sump of the boat. Observe the sonar signal to see if there is a notice-
able decrease in sensitivity. The second bottom signal may disappear
and the bottom signal may decrease in intensity. Move the transducer
around to find the best location. If the sensitivity control has to be
increased greatly to compensate, then the transducer should be
mounted on the outside of the hull. If not, then mark the location that
shot through the hull the best and follow the instructions on the next
pages for a shoot-thru-hull mounting.

1. Make certain the area is clean, dry, and free of oil or grease, then
sand both the inside surface of the hull and the face of the transducer
with 100 grit sandpaper. The surface of the hull must be flat so the entire
transducer face is in contact with the hull prior to bonding.
SPREAD EPOXY HERE
SAND THIS SURFACE
2. Follow the instructions on the epoxy package and mix it thoroughly.
Do not mix it too fast, as it will cause bubbles to form in the epoxy.
Apply a small amount on the face of the transducer as shown above,
then spread a small amount onto the sanded area on the hull. Place the
transducer into the epoxy, twisting and turning it to force any air bubbles
out from under the transducer face. The face of the transducer should be
parallel with the hull, with a minimum amount of epoxy between the hull
and transducer. After the epoxy dries, route the cable to the sonar unit.

TRANSDUCER INSTALLATION - 8° Transducer Only
The 8° transducer is designed for transom mount only. It can be installed
on any outboard or stern-drive powered boat. Do not use this transduc-
ers on an inboard powered boat.
Please read these instructions carefully before installing your trans-
ducer. The transducer mounting location is the most critical part of a
sonar installation. If it isn’t done properly, the sonar can’t perform to its
potential.
ASSEMBLY
1. Locate the four ratchets in the transducer's hardware package. Note
there are letters engraved into one side of each ratchet. These are for
the coarse angle adjustment. A standard transom angle is 14 de-
grees. By aligning a letter on the ratchet to the alignment mark on the
the transducer bracket, the correct transducer angle can be attained.
Once you've determined the correct angle, press one ratchet on each
side of the transducer and one ratchet on each transducer bracket as
shown below.

2. Once you've determined the proper ratchet placement, assemble the
transducer and bracket as shown above. Don't tighten the nut at this
time.
INSTALLATION - Location
1. The transducer must be placed in a location that has a smooth flow of
water at all times. Air bubbles created by the movement of the boat
hull against the water interfere with the sonar signal. This causes
“noise” or random marks to appear on the sonar’s display. You may
need to carefully view the water’s path at the transom while the boat
is moving to determine the best location for the transducer.
2. Make certain the chosen location doesn’t interfere with the boat’s
trailer. Mount the transducer at least one foot from the engine’s lower
unit. This will prevent air bubbles from the transducer interfering with
the propeller.

3. Don’t mount the transducer directly behind strakes or ribs on the
bottom of the hull. Typically, a good location on aluminum boats is
between the ribs closest to the engine.
4. Once you determine the best location for the transducer, hold the
bracket against the transom. The transducer should be roughly paral-
lel to the ground. The bottom of the hull should be about halfway
between the centerline of the transducer and its bottom. (See the
illustration below.)
Mark the transom in the center of each slot in the transducer bracket.
Now drill one hole in the center of each slot. Use #12 stainless steel
screws (not included) to loosely attach the brackets to the transom.
5. Adjust the transducer and bracket so that the front of the transducer is
slightly lower than the back. See the section on fish arches in this
manual for proper transducer angles. Tighten all screws. Clamp the
transducer cable to the transom close to the transducer. This will
prevent the transducer from entering the boat should it be knocked
off at high speed.
Download from Www.Somanuals.com. All Manuals Search And Download.
6. Route the transducer cable to the sonar unit. Keep the transducer
cable away from other wiring on the boat, if possible. Electrical noise
from engine wiring or bilge pumps can be picked up on the trans-
ducer cable. This can show up as unwanted interference on the
sonar display.
FLAT-BOTTOM HULL
DEEP-"VEE" HULL
NOTE: Some aluminum boats with strakes or ribs on the outside of the
hull create large amounts of turbulence at high speed. These boats
typically have large outboard motors capable of propelling the boat at
speeds over 35 mph. The transducer should be mounted as far below
the hull as possible on these boats. This will place the face of the
transducer below the turbulent water, allowing the sonar unit to work at
high speeds.
7. Make a test run to determine the results. If there is interference on the
display when running the boat at high speed, try lowering or changing
the angle of the transducer.
NOTE
Periodically wash the transducer's face with soap and water to
remove any oil film. Oil and dirt on the face will reduce the
sensitivity or may even prevent operation.
CAUTION!

GRAYLINE®
GRAYLINE lets you distinguish between strong and weak echoes. It
“paints” gray on targets that are stronger than a preset value. This allows
you to tell the difference between a hard and soft bottom. For example, a
soft, muddy or weedy bottom returns a weaker signal which is shown with
a narrow or no gray line. A hard bottom returns a strong signal which
causes a wide gray line.
If you have two signals of equal size, one with gray and the other without,
then the target with gray is the stronger signal. This helps distinguish
weeds from trees on the bottom, or fish from structure.
GRAYLINEisadjustable.SinceGRAYLINEshowsthedifferencebetween
strong and weak signals, adjusting the sensitivity may require a different
GRAYLINE level, also. The level chosen by the sonar unit at power on is
usually adequate for most conditions. Experiment with your unit to find the
GRAYLINE setting that’s best for you.

FISH ID
The Fish ID feature identifies targets that meet certain conditions as fish.
The microcomputer analyses all echoes and eliminates surface clutter,
thermoclines, and other signals that are undesirable. In most instances,
remaining targets are fish. The Fish ID feature displays symbols on the
screen in place of the actual fish echoes. There are four fish symbol sizes:
tiny, small, medium, and large. These are used to designate the relative
size between targets. In other words, it displays a small fish symbol when
it thinks a target is a small fish, a medium fish symbol on a larger target, etc.
Themicrocomputerissophisticated,butitcanbefooled.Itcan'tdistinguish
between fish and other suspended objects such as trotlines, turtles,
submerged floats, air bubbles, etc. Individual tree limbs extending out-
wards from a group of limbs is the hardest object for the Fish ID feature to
distinguish from fish.
You may see Fish ID symbols on the screen when actually, there are no
fish. Practice with the unit in both the Fish ID mode and without to become
more familiar with the Fish ID feature.
When the unit is turned on for the first
time, the Fish ID feature is automati-
cally turned off. To turn the Fish ID
feature on, press the menu key, then
press the arrow keys until the FISH ID
menu appears. Press the right arrow
key to turn the fish ID feature on. To
turn the Fish ID feature off again, re-

Any targets the microcomputer deter-
mines are fish will be displayed as fish
symbols.
Remember,theFishIDfeaturecan’tbeusedwhentheunitisinthemanual
mode. If you turn the Fish ID feature on when the unit is in manual, the
microcomputer will turn the automatic feature on. If you turn automatic off
when the Fish ID feature is on, the Fish ID feature will be turned off also.
FISHTRACK™
The FishTrack feature shows the depth of a fish symbol when it appears
on the display. This lets you accurately gauge the depth of targets. This

ADJUST CHART SURFACE
CLARITY (SCC)
The markings extending downward
from the zero line on the chart are
called “surface clutter.” These mark-
ings are caused by wave action, boat
wakes, temperature inversion, and
other natural causes.
The Surface Clarity Control (SCC) re-

sensitivity of the receiver, decreasing it near the surface and gradually
increasing it as the depth increases. The maximum depth that SCC will
affect is 75% of the selected depth range. For example, on a 0-60 foot
range with maximum SCC, surface clutter will be reduced down to 45 feet.
There are three levels of SCC available: low, medium, and high. When it’s

ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the sonar unit that
constantly evaluates the effects of boat speed, water conditions, and
interference. This automatic feature gives you the best display possible
under most conditions.
The ASP feature is an effective tool in
combatingnoise.Insonarterms,noise

electricalandmechanicalsourcessuch
as bilge pumps, engine ignition sys-
tems and wiring, air bubbles passing
over the face of the transducer, even
vibration from the engine. In all cases,
noise can produce unwanted marks
on the display.
The ASP feature has two levels - Nor-
mal and High. If you have high noise
levels, try using the “High” ASP setting. However, if you are having trouble
with noise, we suggest that you take steps to find the interference source
and fix it, rather than continually using the unit with the high ASP setting.
However, there are times when you may want to turn the ASP feature off.
This allows you to view all incoming echoes before they are processed by
the ASP feature.
To change the ASP level, press the MENU key then press the up or down
arrow keys until the "ASP" menu appears. Now use the left or right arrow
keys to change it. When you're finished, press the EXIT key to erase the

TROUBLESHOOTING
If your unit is not working, or if you need technical help, please use the
following troubleshooting section before contacting the factory customer
service department. It may save you the trouble of returning your unit.
Unit won’t turn on:
1. Check the power cable’s connection at the unit. Also check the wiring.
2. Make certain the power cable is wired properly. The red wire connects
to the positive battery terminal, black to negative or ground.
3. Check the fuse.
4. Measure the battery voltage at the unit’s power connector. It should be
at least 11 volts. If it isn’t, the wiring to the unit is defective, the battery
terminals or wiring on the terminals are corroded, or the battery needs
charging.
Unit freezes, locks up, or operates erratically:
1. Electrical noise from the boat’s motor, trolling motor, or an accessory
may be interfering with the sonar unit. Rerouting the power and
transducer cables away from other electrical wiring on the boat may
help. Route the sonar unit’s power cable directly to the battery instead
of through a fuse block or ignition switch
2. Inspect the transducer cable for breaks, cuts, or pinched wires.
3. Check both the transducer and power connectors. Make certain both
are securely plugged in to the unit.
Weak bottom echo, digital readings erratic, or no fish signals:
1. Makecertaintransducerispointingstraightdown.Cleanthefaceofthe
transducer.Oil,dirt,andfuelcancauseafilmtoformonthetransducer,
reducing its effectiveness. If the transducer is mounted inside the hull,
be sure it is shooting through only one layer of fiberglass and that it is
securelybondedtothehull. DoNOTuseRTVsiliconerubberadhesive
or Marinetex
2. Electrical noise from the boat’s motor can interfere with the sonar. This
causes the sonar to automatically increase its Discrimination or noise
rejection feature. This can cause the unit to eliminate weaker signals
such as fish or even structure from the display.

3. The water may be deeper than the sonar’s ability to find the bottom. If
the sonar can’t find the bottom signal while it’s in the automatic mode,
the digital will flash continuously. It may change the range to limits far
greater than the water you are in. If this happens, place the unit in the
manual mode, then change the range to a realistic one, (for example,
0-100 feet) and increase the sensitivity. As you move into shallower
water, a bottom signal should appear.
4. Check the battery voltage. If the voltage drops, the unit’s transmitter
power also drops, reducing its ability to find the bottom or targets.
Bottom echo disappears at high speeds or erratic digital reading or
weak bottom echo while boat is moving
1. The transducer may be in turbulent water. It must be mounted in a
smooth flow of water in order for the sonar to work at all boat speeds.
Air bubbles in the water disrupt the sonar signals, interfering with its
ability to find the bottom or other targets. The technical term for this is
Cavitation.
2. Electrical noise from the boat’s motor can interfere with the sonar. This
causes the sonar to automatically increase its Discrimination or noise
rejection feature. This can cause the unit to eliminate weaker signals
such as fish or even structure from the display. Try using resistor spark
plugs or routing the sonar unit’s power and transducer cables away
from other electrical wiring on the boat.
No fish arches when the Fish ID feature is off:
1. Make certain transducer is pointing straight down. This is the most
common problem if a partial arch is displayed.
2. The sensitivity may not be high enough. In order for the unit to display
a fish arch, it has to be able to receive the fish’s echo from the time it
enters the cone until it leaves. If the sensitivity is not high enough, the
unit shows the fish only when it is in the center of the cone.
3. Use the Zoom feature. It is much easier to display fish arches when
zoomedinonasmallrangeofwaterthanalargeone.Forexample,you
will have much better luck seeing fish arches with a 30 to 60 foot range
thana0to60footrange. Thisenlargesthetargets, allowingthedisplay
to show much more detail.
4. The boat must be moving at a slow trolling speed to see fish arches.
If the boat is motionless, fish stay in the cone, showing on the screen
as straight horizontal lines.

NOISE
A major cause of sonar problems is electrical noise. This usually appears
onthesonar’sdisplayasrandompatternsofdotsorlines.Inseverecases,
it can completely cover the screen with black dots, or cause the unit
operate erratically, or not at all.
Toeliminateorminimizetheeffectsofelectricalnoise,firsttrytodetermine
the cause. With the boat at rest in the water, the first thing you should do
is turn all electrical equipment on the boat off. Make certain the engine is
off, also. Turn the sonar unit on, then turn off ASP (Advanced Signal
Processing). There should be a steady bottom signal on the display. Now
turn on each piece of electrical equipment on the boat and view the effect
on the sonar’s display. For example, turn on the bilge pump and view the
sonar display for noise. If no noise is present, turn the pump off, then turn
ontheVHFradioandtransmit.Keepdoingthisuntilallelectricalequipment
hasbeenturnedon,theireffectonthesonardisplaynoted,thenturnedoff.
If you find noise interference from an electrical instrument, trolling motor,
pump,orradio,trytoisolatetheproblem.Youcanusuallyreroutethesonar
unit’s power cable and transducer cable away from the wiring that is
causing the interference. VHF radio antenna cables radiate noise when
transmitting, sobecertaintokeepthesonar’swiresawayfromit. Youmay
need to route the sonar unit’s power cable directly to the battery to isolate
it from other wiring on the boat.
Ifnonoisedisplaysonthesonarunitfromelectricalequipment, thenmake
certaineverythingexceptthesonarunitisturnedoff, thenstarttheengine.
Increase the RPM with the gearshift in neutral. If noise appears on the
display, the problem could be one of three things; spark plugs, alternator,
or tachometer wiring. Try using resistor spark plugs, alternator filters, or
routing the sonar unit’s power cable away from engine wiring. Again,
routing the power cable directly to the battery helps eliminate noise
problems. Make certain to use the in-line fuse supplied with the unit when
wiring the power cable to the battery.
When no noise appears on the sonar unit after all of the above tests, then
the noise source is probably cavitation. Many novices or persons with
limited experience make hasty sonar installations which function perfectly
in shallow water, or when the boat is at rest. In nearly all cases, the cause
of the malfunction will be the location and/or angle of the transducer. The
face of the transducer must be placed in a location that has a smooth flow
of water at all boat speeds. Read the transducer installation section in this
manual for the best mounting position.
