SVS-760 Introduction

Fishfinder - How it works-

The SVS-760 echo sounder consists of a transceiver display unit and a dual frequency transducer.
An electronic signal pulse is generated in the transmitter section of the display unit. When coupled to
the transducer, this signal is converted into an ultrasonic signal and is transmitted toward the bottom.
The signal travels through the water until it strikes an object or the bottom. It is reflected back , hits the
transducer surface, and is reconverted into an electronic signal by the transducer. Then it is amplified
in the receiver section, processed in the main logic section, and displayed, as an image on a LCD
screen. (Picture 3)
When your boat travels from point A to point B as shown in Picture 1, the beam of the transducer
installed on your boat shown a cross-sectional view in the water.
Picture 2 indicates a cutaway view under the water when your boat moves from A to point B.

The screen shows the latest scan data at its right position. After the next
scan, the previous data is moved to the left and the latest scan data is
shown at the right position. When your boat moves from point A to point B,
the screen shows the scan data as shown in Picture 3.

Installation of the SVS-760

A careful installation will assure maximum performance from your new SVS-760.

Display Unit Location

Select a location for your Display unit that provides easy viewing from all likely operator’s positions.
The display unit is designed to be mounted on either a console or from an overhead surface. The
Display unit is also designed for flush mounting using six threaded holes on the rear panel. Locate the
display in an area with protection from the elements and avoid direct sunlight on the viewing window.
Also, consider access to the rear panel of the unit for connecting power and cables to the various
remote sensors. The mounting surface must be flat and solid to support the unit and prevent vibration.
There should be access to the inside of the surface to permit through bolt fastening for the mounting
bracket.

Display Unit Installation

Temporarily install the mounting bracket on the SVS-760 display unit and place the unit at the selected
location.

CAUTION
The Display unit is unstable when the mounting bracket is not secured. Hold the unit in place
at all times.

Check the suitability of the location and make any adjustments. When all is satisfactory, use the holes
in the mounting bracket as a guide and mark the holes locations on the mounting surface.

- 18 -

Installation

Drill a 1/4 in. diameter hole at each marked location. Mount the Display unit bracket using bolts
through the mounting surface. Place large flat washers on the opposite side of the mounting surface
from the bracket and then install lock washers and nuts. Tighten securely.

Install the display unit into the mounting bracket. Check alignment and operation of the pivots and
security of the mounting. Make any adjustments necessary to prevent binding and assure even
meshing of the pivot locking washers. It is advised to remove the display unit and store it in a safe
place to prevent damage during the rest of the installation process.

Power Connection

Power is supplied to the Fishfinder Unit through a connector on the rear panel of the display unit.
Route the power cable from the Fishfinder Unit location to the ship’s power distribution panel.
Connect the black wire to a battery negative (-) terminal of the power panel.
Connect the white wire to a fused battery positive (+) terminal of the power panel ( 12 to 24 Vdc
nominal). If a fused terminal is not available, install an in-line fuse holder.

Transducer Connection

There are many transducers available which may be used to expand the capabilities of the SVS-760
Fishfinder Unit. Connectors for these accessories are provided on the rear panel of the Fishfinder Unit.

Installation

Installing the Transducer Cable-

Thru-Hull and transom-Mount Installation
cable, with the connector attached, is supplied with the transducer. During the installation, do not cut
the transducer cable or remove the connector. Do not try shorten or splice the cable. The

transducer cable includes several wires, along with shielding and insulation. If the cable is cut, it
cannot be repaired. (Cutting the cable will also void the warranty.) During installation, if you need to
drill any holes for the cable, they must be large enough to accept the connector .(3/4" or 19mm)
This will allow you to complete the installation without cutting the wire.

1st) For a transom-mount installation - Route the cable up and over the top edge of transom. Secure
the cable using cable clamps. (These clamps are available from your local marine equipment supplier.)
If you do not want to expose the cable on the deck, you may drill a new hole (3/4" or 19mm) through
the transom for the cable. (Remember - this hole must be large enough to accept the cable with the
connector attached. Do not cut the cable!) To seal the opening, use a feed-thru cap where the cable
passes through the transom.

2nd) For either type of installation - Run the cable through the interior of the boat.

3rd) Be careful not to tear the cable jacket when passing it through bulkheads and other parts of

your boat. Secure the cable in place using Nylon Wire Ties. Coil the extra cable and tie it out of the
way.

4th) If transducer cable is not long enough, 15 & 30 foot extension cables are available from SI-TEX
When you attach the extension cable, be sure that the connections are tight and watertight. Use Dow
Corning DC-4 or an equivalent sealing compound to protect the connector assemblies.

- 21 -

Installation

Installing the Power Cable-

1st) The 6-foot power cable supplied with the display unit should reach the source of DC power.

Connect the power leads directly to the main battery isolation switch or breaker, or route the power
leads to the DC power distribution panel. At the power source, connect the red wire to the positive
terminal (+), and the black wire to the negative terminal (-). The negative terminal may also be called
"ground" or "earth." (The display unit is internally protected if you accidentally reverse the polarity of
the power wires.)

2nd) Attach the red or positive wire to a 5 amp circuit breaker. If the unit is connected directly to the
boat's battery, include a 2amp in-line fuse. (In-line fuses are available at most marine supply stores.)

3rd) To prevent any interference or electrical noise, separate the Fishfinder power wiring as much as
possible from other devices. See the section on "EMC Installation Guidelines."

4th) If you need to extend the power wiring by more than 10 feet, use a larger wire size. This will
allow the wires to deliver the correct voltage in spite of the longer wire distance. For runs of 20 to 35
feet, use #14 AWG wire. If you need to extend the power wiring, be sure all electrical connections
are solid and durable. Insulate all connections using heat-shrink tubing or electrical tape. You may use
crimp connectors or a terminal strip, but be sure to use good-quality marine-grade parts.

5th) Plug in the power cable at the rear of the display unit.

6th) When you press the Power button, the display unit should turn on. If the unit will not turn on and

you suspect that you may have reversed the power connections, check the DC power lines all the way
back to the battery. If the polarity is not correct, reconnect the leads properly and try again.
(The display unit is internally protected if you accidentally reverse the polarity of the power wires.)

- 22 -

Installation

Installing a Thru-Hull Transducer

Follow these instructions if you are installing the thru-hull transducer.
1st) Once you have decided where to install the transducer, drill the hole for the part. Begin by

drilling a small pilot hole (1/8" or 3mm) from the inside of the hull. (This small hole can be filled easily if
the mounting location is not suitable.) Before you drill the hole, be sure you will be able to reach the
large nut on the top of the transducer, once it has been mounted. Also be sure there will be enough
clearance for the cable. If there is a strake or other feature on the hull, drill from the outside of the hull
instead.

2nd) Drill a larger hole from the outside of the hull using the appropriate size hole saw or paddle bit
for the selected transducer.

3rd) Uncoil the transducer cable. Remove the large hex nut from the housing and slide it over the end
of the cable.

4th) Thread the cable through the hole to the inside of the hull. Never pull or carry the transducer in
place by pulling on the transducer cable.

5th) Apply a thin layer of sealant (1/8"" or 3mm) to the transducer between the upper flat surface of
the transducer and the faring block. Use a high quality marine sealant suitable for underwater use.
(Caution do not use 3M 5200) Also apply a thin layer up the side walls. this should cover all of the
threads where the part will touch the hull material, plus an additional 1/4""(6mm). This will seal the
threads for the large hex nut.

6th) Push the transducer housing (with the sealant applied) into the hole from the outside of the hull.
Twist the housing slightly to squeeze out any excess sealant and to get a good seal. Be sure that the
transducer is aligned so that the correct part of the unit is toward the bow of the vessel. Hold or prop
the transducer in place temporarily.

- 23 -

Installation

Installing a Thru-Hull Transducer
7th) Go to the inside of the hull and slide the hex nut over the end of the cable. Fit the hex nut over

the end of the transducer and tighten it. (On a vessel with a wooden hull, do not tighten the nut
completely right away. Allow some time for the wood to swell after the vessel is put in the water. Be
sure that the correct end of the transducer is pointing forward see Picture 1-1
8th) Remove any excess sealant from the outside of the unit to assure smooth water flow over the
face of the transducer.
9th) As soon as the boat is placed in the water, check for leaks. Check again within 3 to 5 hours.
(You may not be able to see a small leak right away.) If there are any leaks, you must repeat the
installation procedure.

- 24 -

Installation

Positioning the Transom-Mount Transducer

Follow these instruction if you are installing the transom-mount transducer.
Begin by finding the best location for the mounting bracket. Here are the rules:
If your boat has one propeller (outboard or inboard-outboard), mount the transducer about
18"(455mm) to the side of the centerline of the boat. See Picture 1-2 Choose the side that is on the
down stroke of the propeller.(This is usually the starboard side of the boat.) This will reduce any
interference cause by air bubbles.
If your boat has twin propellers (outboard or inboard-outboard), place the transducer near the
centerline of the boat.
If the propeller can be turned to steer the boat, allow at least 2"(50mm) beyond the swing radius of the
propeller. This will prevent the propeller from damaging the transducer when it is turned.
Do not mount the transducer behind any hull fittings, intakes, or other parts which extend from the hull.
These may cause turbulence or air bubbles.

If the boat will be carried
on a trailer, be sure the
transducer will not hit any
rollers, bunks or fittings
on the trailer.

- 25 -

Installation

Mounting the Transom-Mount Transducer

Follow these instructions if you are installing the transom-mount transducer.
1st). On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8""(3.2mm) to
1/4""(6mm) below the bottom edge of the hull. See picture 1-3. On an aluminum hull, the transducer
should extend a bit more - 1/4"(6mm) to 3/8"(9mm). If the boat will be operated at high speeds, the
transducer may be mounted closer to the centerline of the hull.

2nd) The lower surface of the transducer should tilt down toward the rear at a slight angle(2° to 5°). The
mounting bracket includes a wedge. Depending on the angle of the transom on your boat, you may
need this wedge to get the correct angle for the bottom of the transducer.

3rd) Looking at the rear of the boat, be sure the bracket is vertical (perpendicular to the water line).

4th) Hold the bracket (and the wedge, if used) against the transom and trace the position of the screw

slots.

5th) Remove the bracket. The screws in the outer slots should be placed about 1/4"(6mm) up from
the bottom of each slot. The screw in the center slot should be placed 1/4" (6mm) down from the top.
(This will allow you to adjust the bracket up or down a bit.)
Drill pilot holes 3/4""(19mm) deep. Use a 9/64" (3.5mm) drill bit. To prevent drilling too deeply, wrap
masking tape around the drill bit about 7/8" (22mm) from the tip. Drill in only as far as the tape marker.
If you are attaching the bracket to a fiberglass hull, you can minimize any surface cracking of the gel
coat. Before drilling each pilot hole, drill a shallow hole (chamfer) at each location about 1/16" (1.5mm)
deep. Use a 1/4"(6mm) drill bit.

6th) Attach the bracket to the hull using the pinhead screw with flat washers. Before you tighten the
screws, apply a good-quality marine sealant to the pilot hole. This will protect the hull from water
penetration. Do not tighten the screws completely yet.

- 26 -

Installation

7th) Tilt the transducer in the brackets until it is positioned as illustrated in Picture 1-3
8th) Once the bracket is in the correct position, you can tighten the screws.
