INSTALLATION - Bracket
You can install the unit on the top of a dash or from an overhead with the
supplied bracket. It can also be installed in the dash with an optional IDA-
3 or IDA-4 mounting kit. If you use the supplied bracket, you may be
interested in the optional GBSA-1 swivel bracket kit. This converts the
gimbal bracket to a swivel mount which can be used on the dash or
overhead mounting positions. Installation instructions for the in-dash and
swivel mounting kits are supplied with the adapter kits.
Mount the unit in any convenient location, provided there is clearance

PERMANENT MOUNT TRANSDUCER INSTALLATION
The HS-WSPC supplied with your sonar is a transom mount transducer.
It can be installed on any outboard or stern-drive (inboard\outboard)
powered boat.
The “kick-up” mounting bracket helps prevent damage 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 the enclosed transducer installation instructions carefully before
attempting the installation. Determine which of the mounting positions is
right for your boat. Use extreme care when mounting the transducer,
since the transducer location is the most critical part of a sonar installa-
tion. If it isn’t done properly, the sonar can’t perform at it’s designed
potential.
Location - General
1. The transducer must be placed in a location that has a smooth flow
of 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 ran-
dom lines or dots whenever the boat is moving.
2. The transducer should be installed with it’s face pointing straight
down, if possible.
3. Make certain the transducer's location doesn’t interfere with the
trailer or hauling of the boat. Also, don’t mount it closer than approxi-
mately 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 trans-
ducer cable around these wires.
CAUTION!
CLAMP THE TRANSDUCER CABLE TO
TRANSOM NEAR THE TRANSDUCER. THIS
WILL HELP PREVENT THE TRANSDUCER
FROM ENTERING THE BOAT IF IT IS
KNOCKED OFF AT HIGH SPEED.
GOOD LOCATION
Transducer Assembly and Mounting
The best way to install this transducer is to loosely assemble all of the
parts first, then 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.
DOT
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,
6
RATCHETS
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 it does, 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.
3. Once you determine the correct position for the ratchets, assemble
the transducer as shown below. 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 below. At-
tach the transducer to the transom. Slide the transducer up or down
until it’s aligned properly on the transom as shown below. 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 in the cable at the transducer as shown at the bottom of
the previous page. If possible, route the transducer cable away from
other wiring on the boat.Electrical noise from the engine’s wiring, bilge
pumps, VHF radio wires and cables can be picked up by the sonar.
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!
Fish Arches
If you do not get good fish arches on your display, it could be the
transducer is not parallel with the ground when the boat is at rest in the
water, or at slow trolling speeds. If the arch slopes up, but not back
down, then the front of the transducer is too high and needs to be
lowered. If only the back half the the arch is printed, then the nose of the
transducer is angled too far down and needs to be raised.

RANGE
You can’t adjust the range when the auto-
matic mode is on. It is adjustable when the
unit is in the manual mode, however. To do
so, first put the unit in the manual mode. Now
press a menu key until the “RANGE SEL”
menu appears as shown at right. The current

5, 10, 20, 40, 60, 100, 200, and 300 meters.
NOTE: The depth capability of this sonar depends on the transducer
installation, water and bottom conditions, and other factors.
ZOOM
The zoom feature enlarges all echoes on the screen. If the unit is in the
automatic mode, it tracks the bottom signal, always keeping it near the
bottom of the screen. This lets you see small detail, at the same time

SENSITIVITY
The sensitivity menu lets you control the unit’s ability to pick up echoes. A
low sensitivity level excludes much of the bottom information, fish signals,
and other detail. High sensitivity settings lets you see features, but it can
also clutter the screen with noise and other unwanted signals. Typically,
the best sensitivity level shows a good, solid bottom signal with grayline.
This unit adjusts the sensitivity level to keep a solid bottom signal on the
screen. It adds a little extra when it’s in the automatic mode. This gives it
the capability to show fish and other detail. However, situations occur
where it becomes necessary to increase or decrease the sensitivity level.
Typically, this occurs when you wish to see more detail, so you need to
increasethesensitivity. Theproceduretoadjustitisthesamewhetherthe
unit is in the automatic or manual mode.
To change the sensitivity level, first press a
menu key until the sensitivity menu appears.
If the unit is in automatic, the menu shows
“AUTO SENS.” Otherwise, the menu shows
“MAN SENS.” Now press the up arrow key to
increase the sensitivity, the down arrow to
decreaseit. Echoesscrollingontothescreen

FISH ID FEATURE
The Fish ID feature identifies targets that meet certain conditions as fish.
The microcomputer analyses all echoes and eliminates surface clutter,

targets are fish. The Fish ID feature displays symbols on the screen in
place of the actual fish echoes. There are three symbol sizes: small,
medium, andlarge. Theseshowtherelativesizebetweentargets. Inother
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.

FISH ARCHES
Fish arches are created when the cone of sound passes over a fish. The
distance to a fish when the cone first strikes it is shown as "A" below.
When the center of the cone strikes the fish, the distance is shorter as
shown "B". As the cone leaves the fish, the distance increases again as
shown in "C".
When the Fish I.D. mode is off, the depth of the water will affect the size
and shape of the fish arch due to the cone angle diameter. For example,
if the cone passes over a fish in shallow water, the signal displayed on
the unit may not arch at all. This is due to the narrow cone diameter and
the resolution limitations of the display.
Very small fish probably will not arch at all. Medium sized fish will show a
partial arch, or a shape similar to an arch if they’re in deep water. Large
fish will arch, but turn the sensitivity up in deeper water to see the arch.
Because of water conditions, such as heavy surface clutter, ther-
moclines, etc., the sensitivity sometimes cannot be increased enough to
get fish arches.

23
One of the best ways to get fish arches is to expand or “zoom” a
segment of the water. For example, from 45 to 60 feet. The smaller the
segment, the better the screen resolution will be. The easiest way to do
this is with the Zoom feature. This feature expands the echoes, making it
easier to see detail. For the best results, turn the sensitivity up as high as
possible without getting too much noise on the screen. In medium to
deep water, this method should work to display fish arches.
If you see fish signals when the unit is in the manual mode, but don't get
fish symbols when Fish I.D. is on, try increasing the sensitivity.
WATER TEMPERATURE AND THERMOCLINES
Water temperature has an important-if not controlling-influence upon the
activities of all fish. Fish are cold blooded and their bodies are always the
temperature of the surrounding water. During the winter, colder water
slows down their metabolism. At this time, they need about a fourth as
much food as they consume in the summer.
Most fish don’t spawn unless the water temperature is within rather
narrow limits. A surface temperature meter can help you identify the
desired surface water spawning temperatures for various species. Trout
can’t survive in streams that get too warm. Bass and other fish eventu-
ally die out when stocked in lakes that remain too cold during the
summer. While some fish have a wider temperature tolerance than
others, each has a certain range within which it tries to stay. Schooling
fish suspended over deep water lie at the level that provides this tem-
perature. We assume they are the most comfortable here.
The temperature of water in the lake is seldom constant from top to
bottom. Layers of different temperatures form, and the junction of a
warm and cool layer of water is called a thermocline. The depth and
thickness of the thermocline can vary with the season or time of day. In
deep lakes there may be two or more at different depths. Thermoclines
are important to fishermen because they are areas where fish are active.
Many times bait fish will be above the thermocline while larger game fish
will suspend in or just below it.

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
maybeinterferingwiththesonarunit.Reroutingthepowerandtransducer
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 the transducer and power connector. Make certain it's securely
plugged in to the unit.
Weak bottom echo, digital readings erratic, or no fish signals:
1. Make certain transducer is pointing straight down. Clean the face of the
transducer. Oil, dirt, and fuel can cause a film to form on the transducer,
reducing its effectiveness. If the transducer is mounted inside the hull, be
sureitisshootingthroughonlyonelayeroffiberglassandthatitissecurely
bondedtothehull.DoNOTuseRTVsiliconerubberadhesiveorMarinetexTM.
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
thanthewateryouarein.Ifthishappens,placetheunitinthemanualmode,
then change the range to a realistic one, (for example, 0-120 feet) and
increasethesensitivity. Asyoumoveintoshallowerwater, abottomsignal
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
26
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. See the Fish Arch section
in your owner's manual for more information.
2. The sensitivity may not be high enough. In order for the unit to display
afisharch, ithastobeabletoreceivethefish’sechofromthetimeitenters

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
zoomed in on a small range of water than a large one. For example, you

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 display as
straight horizontal lines.
ELECTRICAL 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.Turntheuniton,thenturnoffASP(AdvancedSignalProcessing).
There should be a steady bottom signal on the display. Now turn on each
pieceofelectricalequipmentontheboatandviewtheeffectonthesonar’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 on the VHF
radio and transmit. Keep doing this until all electrical equipment has been
turned on, their effect on the sonar display noted, then turned off.
If you find noise interference from an electrical instrument, trolling motor,
pump,orradio,trytoisolatetheproblem.Youcanusuallyreroutethesonar
27
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.

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
limitedexperiencemakehastysonarinstallationswhichfunctionperfectly
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 instructions in
this manual for the best mounting position.
