GENERAL INFORMATION
The SH-1 Depth Sounder, Figure 1, is a small light-weight unit that is
rugged and versatile enough for any size boat. The SH-1 will indicate
water depth, bottom conditions, and intervening objects, such as fish,
in red color,
The depth sounder transmits bursts of high frequency pulses (200 KHz)
which are converted from electrical to mechanical energy by the trans-
ducer. These pulses radiate from the transducer to the bottom and are
reflected back to the transducer. The transducer converts them from
mechanical vibrations to electrical pulses which are displayed on the
unit's face. These pulses travel at approximately 4800 feet per se-
cond to provide a constant update of water depth and location of inter-
vening objects, such as fish.

INSTALLATION
INDICATOR MOUNTING
The indicator can be mounted in any convenient location that has a flat
surface. The adjustable bracket, Figure 2, permits mounting on either
a bottom or an overhead supporting surface or a bulkhead.
If the indicator is mounted near a magnetic compass, check that it does
not affect the compass readings. If compass readings are affected,
select an alternate mounting site.
Mount indicator where it can be easily viewed, However, it should be
mounted out of direct sun light; otherwise, the sun shield may have to
be used.
Although the unit is splash proof, it should be sheltered from the weather.
(Warranty does not cover water or salt water damage.)

POWER CONNECTION
Connect the plug of the power supply cord to the power supply socket
located in the rear of the cabinet, Figure 3. Connect the red wire
to the positive termina? and the black wire to the negative terminal of
the external battery.
To minimize extraneous electrical interference, the power cord should be
connected directly to the battery terminals, and it should not be routed
in parallel with the transducer cable.

TRANSDUCER INSTALLATION
For proper performance, the transducer moueting location must be choosen
carefully. The transducer should be located in an area that is relatively
free of white water. To determine the best location, run the boat at
varying speeds and observe the water as 1t passes under the transom.
Keep the transducer and its cable as far as possible from the boat's power
cables, tachometer and other electrical cables.
After a suitable location is found, assemble the transducer, Figure 4,
temporarily as outlined below:
1. Use a straight edge to align transducer with the bottom of the hull
and mark the mounting hole location on the transom.
2. Drill foure 1/8&quot; holes and mount the brackets with the screws provided.
Coat the screws with bedding compound to prevent leakage.
3. Position transducer per Figure 5 and tighten nuts and screws.

Figure 5. Transducer and Cable Mounting
Inside Hull Transducer Mount ing In many cases, good results can be
attained by mounting the transducer inside the hull, generally in the bilge
area. It is important to ensure that the transducer is placed in an area
that has a sigle-hull thickness. There must not be any air or flotation
material, other than solid fiberglass, between the transducer's face and
the water. Also, the transducer should not be placed over hull struts
or ribs which generally run under the hull.
To determine the best position for the transducer, put some water in the
bilge, wash the transducer face with a mild detergent and place the trans-
ducer in the bilge so that the transducer face is flush with the hull,
Run the boat at various speeds and move the transducer to different loca-
tions to determine the best location for permanent installation.
To ensure a good transducer installation, drain all the water from the
bilge, thoroughly clean the inside hull where the transducer.is to be
mounted, and clean the transducer face with the recommended detergent.
Allow both to dry completely, then use a good two-part epoxy or fiberglass
resine to bond the transducer face to the hull (coat the transducer face
and hull with epoxy). Press the transducer firmly to the hull and
gently twist back and forth to remove any air which may be trapped in the
epoxy. Allow to dry per epoxy instructions.
The depth sounder will now operate with no water in the bilge. This type
of mounting is preferred, as oily bilge water will tend to make sounding
through the hull more difficult, and the transducer could move around if it
were not secured in place.
This type of transducer mounting works best on fiberglass and aluminum boat,
and in many cases, good-to-fair results can be obtained in wood boats pro-
viding the hull is not too thick and it is void of air.
On fiberglass flotation hulls, Figure 6, the inner hull can be removed and
a reservoir made for transducer placement. After the reservoir is made,
check depth-sounder operation before securing the transducer down.

nsta transducer so that TEs working face will be parallel to the
water line when the vessel 1s in its normal upright position and will
remain submerged when the vessel is heeled and under way. The pointed
end of the transducer must point forward. Since air bubbles will greatly
decrease the efficiency of the transducer and sensitivity of the receiver,
the mounting site should be as far from air bubble streams as possible.
In through-hul) installation, Figure 7, use leveling blocks, as required,
to ensure that the transducer face is parallel to the water line.

Transducer Maintenance
If boating in salt water, paint the transducer with thin coat of antifouling.
Allow time for the face of the transducer to become wet (coupled intimately
to the water) after installation or after retuning to the water from storage.
Clean the face of the transducer with a mild detergent or soap pad if the
transducers *vision&reg; becomes obstructed, which may happen through constant
exposure to the oily waters of a marina, 011 will act as an insulator
and cause the face to become decoupled from the water or unwetted.
Cleaning will restore the signal transmitting and receiving.
If the instrument fails to function, check all transducer electrical con-
nections before calling a serviceman.
Do not coat the face of the transducer with heavily-pegmented antifouling
paints, especially those filled with cuprous oxide, because they reduce the
sensitivity or &quot;vision&quot; of the transducer.
Transducer Connector
The Transducer cable is a two-wire (black and white) shielded cable.
Using a proper stripping tool, prepare the end of the cable as shown in
Figure В.
Unscrew the cable clamping screws and plug-body securing screw of the con-
nector and slide the shell and coupling ring on the cable. Solder the
black lead to terminal No. 1, the white lead to terminal No. 3 and the
shield to terminal No. 2. The terminal identification numbers are indi-
cated on the plug-body face.

INTERFERENCE SUPPRESSION
Interference in sufficient magnitude will cause erratic performance of the
depth finder and possibly cause multiple strobes around the dial.
Check installation for interference by stopping the engine in medium depth
water and observing the depth finder, Then start the engine with the pro-
pel ler disengaged; increase engine RPM and observe the indicator for inter-
erence.
If interference is present, one or more of the following remedies may
affect a cure:
1, Instal) a suppressor on the center lead of the distributor. Install
a coaxial condenser between the ignition coil and the ignition switch.
2. Install coaxial condensers on the electrical power line and the cont-
rol leads which leave the engine compartment.
J. Bond engine, electrical accessories, propeller shaft, and rudder to
each other and to the ground plate, if installed, with heavy copper
grounding straps.
4. Resistor type spark plugs and/or copper screening on the inside of
the engine compartment may be required in extreme cases.
On some engines, Champion “U* type spark plugs (such as UJ6) are specified.
It is virtually impossible to eliminate noise caused by these plugs as they
have an extra spark gap near the top of the plug which causes the leads to
radiate noise. Replace these plugs with a resistor type plug such as the
Champion XJ6, XJ8, etc. Check all high tension wires for continuity.
Ingnition coil should be mounted on the engine. Clean away paint to en-
sure a good ground, Plastic-encased coils radiateexcessive noise and
should be replaced with a standard metalcased unit,
Older types of voltage regulators contain a vibrating set of contacts to
control voltage. If the usual capacitors eliminate the noise, replace
with a solid-state regulator which has no moving parts.
Some electrical tachometers cause considerable radiation of spark noise.
This type of tach connects to the points of the distributor. Disconnect
the tach wire at the distributor, and note the noise reduction. This
lead could be shielded or a special tach filter installed. If SUN tachs
are used, all wires must be shielded and the plastic-cased sender unit,
which contains a vibrating set of contacts, should be completely shielded
in a metal enclosure.
Your authorized marine electronic dealer will be familiar with the methods
of reducing electrical interfernce and is qualified to assist you should
a problem exist.

TROUBLESHOOTING CHART
SYMPTOM
POSSIBLE CAUSE
Unit turned on, no display,
and motor does not run,
Check for power at 12 YDC connector at rear
of unit.
If power is 0.K., check inside unit for
blown fuse. To gain access, remove control
knobs, then remove two Phillips screws from
rear, Carefully separate case and replace
fuse using 1 amp value only.
Unit turned on, no display,
and motor is running.
Display board or other problem that will
require shop service,
Unit works fine when boat
is sitting still or running
at slow speed, but no bottom
return is seen at higher
speed.
Transducer is not in contact with water or
too much white water is under the trans-
ducer face. Check or change transducer
location. The pulse of sound emitted by the
transducer travels at a speed of 4800 feet
per second, so if the unit operates satis-
factorily sitting still, it will work satis-
factorily at any boat speed providing the
transducer is properly located.
Unit works fine when boat's
engine is off but has mul-
tiple strobes around the
dial when engine is running.
Unit is picking up electrical interference
from the boat's engine. Refer to section
on engine interference,
Unit works fine but bottom
light disappears when boat
is in reverse or when
passing over another boat's
wake.
Unit cannot read through white water because
most of the pulse is reflected.
Operation of unit is gene-
rally normal but occasionally
zera light gets wider.
This is generally caused by heavy seas or
wave action pushing tiny air bubbles down,
as deep as 10-15 feet, and the unit is
picking up these alr bubbles and displaying
them as target echoes.
Unit turned on and has zero
mark, but no bottom return
is displayed,
Transducer is not in contact with water.
Transducer connector is not in place.
Bad transducer or broken wire at connector.
