Chapter1:Overview
1.1 Introduction
This handbook provides instructions to assist you in the installation
and set up of the various transducers for Raymarine fishfinders.See
Table 1-1onpage4 for a list of the different sensor, material and
mounting types available.
General
Raymarine fishfinders require atransducer, eitherthru-hull, in-hull,
ortransom-mount.
Transducers can measure water depth, temperature, distance
traveled, and/or speed. It is important to position your transducer
correctly, as described in Section 1.4, Selecting the Equipment
Location.
Note:If speed and temperatureare beinginput via SeaTalk, these
values are displayed instead of the speed and temperature inputs
from the transducer.
This handbook is divided into three chaptersas follows:
Chapter One provides an overview of the transducer installation.It
includessections on Unpacking and Inspecting the Components,
Selecting theTransducerSiteand a descriptionof theCableRuns.
Chapter Twoprovides detailed instructionson how to mount and
connect each type of transducer.
ChapterThreeprovidesinformationonmaintenanceandwhattodo
if you have problems.

EMCInstallationGuidelines
All Raymarine equipment and accessories are designed to the best
industry standardsfor usein theleisuremarineenvironment.
Their design and manufacture conforms tothe appropriate
Electromagnetic Compatibility (EMC) standards, but correct
installation is required to ensure that performance isnot
compromised. Although every efforthas been taken to ensure that
they willperform underall conditions,it isimportant to understand
what factors could affect the operation of the product.
TheguidelinesgivenheredescribetheconditionsforoptimumEMC
performance, butit is recognized that itmay not be possible to meet
all of these conditions in all situations. To ensure the bestpossible
conditions for EMC performance within the constraints imposed by
any location, always ensure the maximum separation possible
between different items of electrical equipment.
For optimumEMC performance, it is recommended that wherever
possible:
•Raymarine equipment and cables connected to it are:
•At least 1 m (3 ft) from any equipment transmitting or cables
carrying radio signals,e.g., VHF radios, cables andantennas.
In the case of SSB radios, the distanceshould be increased to
2 m (7 ft).
•More than 2 m (7 ft) from the path of a radar beam. A radar
beam can normally be assumed to spread 20 degrees above
andbelowtheradiatingelement.
•Theequipment issuppliedfroma separatebattery fromthatused
for engine start. Voltage drops below 10 V (20 Vfor 10 kW open
arrayscanners) inthe powersupplytoour products,and starter
motor transients, can cause the equipment to reset. This will not
damage theequipment, butmay cause the loss of some informa-
tion and may change the operating mode.
•Raymarine specified cables are used at all times. Cutting and
rejoiningthesecablescancompromiseEMCperformanceandso
must beavoided unless doing so is detailedin thedocumentation.
•Ifasuppressionferriteisattachedtoacable,thisferriteshouldnot
be removed.If theferrite needs to be removed during installation
it mustbe reassembled inthe sameposition.

The following illustration shows a typical range of suppression
ferrites fitted to Raymarine equipment.
Connections toOther Equipment
If your Raymarine equipment is to be connected to other equipment
usingacablenotsuppliedbyRaymarine,asuppressionferriteMUST
always be attached to the cable near to the Raymarine unit.
1.2 TheFishfinderSystem
Transducers enable fishfinders to display depth, water temperature
and/or speed, depending on the type of transducer(s) installed.
Beforeyou startthe installation, checkthat youhave the correct
transducer for your application, as described below in Selecting the
Correct Type of Transducer.

Applications
Plastichousings arerecommended for fiberglass or metal hulls.
Bronze housings are recommended forwood or fiberglass hulls.
•Installationofabronzehousinginametalhull requiresusingofa
fairing,availablefrom yourRaymarine dealer.
•Never installa metalhousinginavesselwitha positiveground

TransomMountTransducersare recommended for personal
watercraft and powerboats with outboard, inboard-outboard and jet
drives. They are NOT recommended for large or twin screw inboard
boats.
•Adjuststo transom angles from 3°–16°. For angles greater than
16°, a tapered plastic, wood or metal shim will be needed.
•Designedforoperationfrom5 –58 m.p.h. (4–50knots).
Thru-Hull Transducers are recommended for boats with straight-
shaftinboard engines.
In-Hulltransducersarerecommendedforfiberglasshulls,especially
in highspeed power boats and racing sailboats.
Planningthe Installation
Beforeyou installyour system, plantheinstallation,considering:
•Location of the transducer and fishfinder, as described in
Section 1.4
•CableRuns,includingcablesforanintegratedsystem(toprovide
heading and position data, etc.), as described in Section 1.5.

1.3 UnpackingandInspectingtheComponents
Unpack your system carefully, to prevent damage to the equipment.
Save the carton and packing, in case you need to return a unit for
service.
Checkthat youhave allthecorrectsystem components. These
dependon yoursystem package,asfollows:

Acousticnoiseisalwayspresentandthesesoundwaves caninterfere
withthe operation of the transducer. Ambient(background) noise
from sources such as waves, fish, rain and other vessels cannot be
controlled. Carefully selecting the transducer’s mounting location
can minimize noise generated by the vessel’s propeller(s), shaft(s),
machinery, and other echo sounders. The lower the noise level, the
higher the echo sounder gain that can be used, and the better the
Fishfinder’s performance.
CAUTION:
Toensureaccuratereadings,DONOTmountthetransducerin
an area of turbulence or bubbles:
• nearwaterintakeordischarge openings
• behindstrakes, fittings or hullirregularities
• behind eroding paint (an indication of turbulence)
Choosea location where:
•Thewaterflowingacrossthehullissmoothestwithaminimumof
turbulence and bubbles (especially at high speeds).
•The transducer will be continuously covered by water when the
boat is moving. If the transducer is mounted near the side of the
boat, it may beexposed when the boat is turning.
•The transducer beamis unobstructedby the keel or propeller
shaft.
•There is a minimum deadrise angle.

1.5 CableRuns
Consider the following before installing the system cables:
•You need to attach the power cable and the transducer cable.
Additional cables will berequired if youare installing an inte-
grated system.
•Allcablesshouldbeadequatelysecured,protectedfromphysical
damage and protected from exposure to heat. Avoid running
cables throughbilges or doorways, orclose to moving or hot
objects.
•Acute bends must be avoided
•Where a cable passesthrough anexposed bulkhead or deckhead,
awatertightfeed-through shouldbeused.
•Secure cables in place using tie-wraps or lacing twine. Coil any
extra cable and tie it out of the way.
TransducerCable
A 30 ft (10m) cable is supplied with the transducer. The transducer
cablemaybeextendeduptoamaximumof60ft(20m)using
optionalextension cables.
Thetransducercableconnectorhasanutthathasbeenremovedtoaid

the cable, ensure that any holes youdrill arelargeenough toaccept
the connector, with thenut removed.
After the cable has been run throughthe holes, thisnut must be
attached before the cable can be connected, as described in
Transducer Cable Connections onpage 39.
CAUTION:
