1 – Introduction

About the FishFinder L265

The FishFinder L265 is a system that uses sound waves (“sonar”) to
detect fish and show the bottom of a lake or sea. The system includes a
transducer and a display unit, connected by a cable. The transducer
sends high-frequency sound waves down into the water. These sounds
strike fish, the bottom, or other objects in the water, and return as echoes.
The FishFinder then interprets these echoes and presents a display.

The FishFinder L265 can handle many different jobs:

• detect the presence of fish below the boat

• trigger an alarm when fish are found

• measure the depth of the water

• set alarms for minimum and maximum depth

• show the shape of the bottom

• determine whether the seabed is hard or soft
We are sure you will find the FishFinder L265 to be one of the most useful
devices on your boat.

2 – Installation

The installation process has four parts:

• Mounting the transducer

• Mounting the display unit

• Connecting the cables for the transducer and power supply

• Calibrating the display unit

About the Transducer

Several different kinds of transducers can be used with this unit. The
transom-mount style, used most often, and in-hull types are shown in Fig.
2-1.

All of these transducers measure the water depth. An optional
transducer, the Sidelooker, detects objects by looking out to the sides of
the boat.

Since the transducer is very important to the operation of the FishFinder,
it is vital that the transducer be mounted correctly. The transducer will
give the most reliable readings if it looks into water which is smooth and
undisturbed. If you place the transducer so bubbles or turbulence flow
across the face of the unit, the system may give inaccurate readings.

There are three important rules when mounting any type of transducer:

• The transducer should be continuously covered by water when the

boat is moving. (If the transducer is mounted near the side of the
boat, it may be exposed when the boat is turning.)

• The transducer should be placed where turbulence or bubbles will not

pass directly over the face of the unit. Don’t place the transducer
behind any running strakes, intakes, or thru-hull fittings which create
turbulence.

• The transducer should be mounted where it will not be affected by the

wash from the propeller(s).

Selecting the Correct Type of Transducer

Before you begin the installation, double-check to be sure you have the
correct type of transducer. Each kind of transducer is designed for a

particular type of use. In this manual we will include detailed mounting
instructions for the transom-mount transducer. We will also include some
general information on the other types. For detailed information on these
other transducers, see the instructions which are packaged with the unit.

Use a transom-mount transducer if –

. . . your boat has an outboard or inboard-outboard engine(s), and if you’re
planning to use the Sidelooker option. This type of transducer must be
mounted ahead of or beside the propeller(s). Do not use this type of
transducer for a boat with a straight-shaft inboard engine.

Use a thru-hull transducer if –

. . . your boat has a straight-shaft inboard engine. This type of transducer
is installed in a hole drilled through the hull.

Installation

5

Use a low-profile transducer if –

. . . you want minimum water resistance on a high-performance boat or
sailboat. The bottom of the boat must be flat, or have a deadrise angle of no
more than 10°.

Use an in-hull transducer if –

. . . you have a high-speed boat or if, for some reason, you cannot use a
transom-mount or thru-hull transducer. The hull may be no more than 1" thick.

Use a trolling motor transducer if –

. . . you want to attach the transducer to a trolling motor. (Not recom­mended for deep-water operations.)

Use a Sidelooker transducer –

. . . for searching for fish or structure on either side of the boat. This type
of transducer is attached to the bracket of the transom-mount transducer,
or to the shaft of the trolling motor.

Positioning 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” (455 mm) to the side of the centerline of the
boat. See Fig. 2-3. Choose the side that is on the downstroke of the
propeller. (This is usually the starboard side of the boat.) This will
reduce any interference caused by air bubbles.

Installation

• If the propeller can be turned to steer the boat, allow at least 2" (50 mm)
beyond the swing radius of the propeller. This will prevent the
propeller from damaging the transducer when it is turned. After
installation, check the clearance by turning the wheel so the propeller
swings toward the transducer. There should always be a 2” (50 mm)
clearance.

• If your boat has twin propellers (outboard or inboard-outboard), place
the transducer near the centerline of the boat.

•

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.

• The bracket has a quick-release mechanism. This may reduce
damage by allowing the transducer to flip up if it hits any debris or the
bottom. See Fig. 2-4. Allow enough clearance above the transducer
so that it can swing upward completely. This is about 10" (254 mm)
measured from the bottom of the transom.

• If considering the Sidelooker option, look for a mounting location
where the Sidelooker array will not be blocked by the engine housing
or other mounted hardware.

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

Mounting the Transom-Mount Transducer

1. On a boat with a fiberglass hull, the leading edge of the transducer
should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge of
the hull. See Fig. 2-5. On an aluminum hull, the transducer should
extend a bit more – 1/4" (6 mm) to 3/8" (9 mm). If the boat will be
operated at high speeds, the transducer may be mounted closer to
the centerline of the hull.

2. 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.

4. Hold the bracket (and the wedge, if used) against the transom and

at the rear of the boat, be sure the bracket is vertical (perpen-

Installation

5. Remove the bracket. See Fig. 2-6. The screws in the outer slots
should be placed about 1/4" (6 mm) up from the bottom of each slot.
The screw in the center slot should be placed 1/4” (6 mm) down from
the top. (This will allow you to adjust the bracket up or down a bit.)
Drill pilot holes 3/4" (19.1 mm) deep. Use a 9/64" (3.6 mm) drill bit.
To prevent drilling too deeply, wrap masking tape around the drill bit
about 7/8" (22 mm) 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" (1.5 mm)
deep. Use a 1/4" (6 mm) drill bit.

6. Attach the bracket to the hull using the panhead screws with flat
washers. Before you tighten the screws, apply a good-quality marine
sealant to the pilot holes. This will protect the hull from water penetra­tion.

Do not tighten the screws completely yet.

7. Move the bracket up or down so that the leading edge of the trans­ducer has the clearance shown in Fig. 2-5.

8. Once the bracket is in the correct position, you can tighten the
screws.

Mounting the Optional Sidelooker Transducer

1. The Sidelooker transducer allows the display unit to check the water
to either side of the boat. This is helpful when you are looking for fish
or structure near river banks, or under docks or piers.

2. The M78930 Sidelooker transducer is attached to the same mounting
bracket used with the transom-mount transducer. See Fig. 2-7.
Begin by installing the transom-mount bracket as described earlier.

3. Remove the two screws and brackets covering the paddlewheel.

4. Attach the Sidelooker transducer to the top of the transom mounting
bracket. Use the four panhead screws supplied. The fit should be
snug, but do not overtighten the screws.

5. Run the Sidelooker cable beside the depth cable for the transom­mount transducer.

Installation Notes – Thru-Hull Transducer or
Low-Profile Transducer

The installation process for these two types is almost the same. Detailed
instructions for this installation will be included with the transducer. In this
section, we will note just a few important points.

1. Earlier we listed three general rules for placing transducers. All of
these rules apply when you are mounting a thru-hull or low profile
transducer. Here are some other rules for selecting the best mount­ing location:
For planing hulls – Install in the flat planing area near the stern.
Always install forward of the propeller(s) and shaft(s).
For small displacement hulls – Install near the centerline of the hull
and 1/3 of the way forward from the stern. Always install forward of
the propeller(s) and shaft(s).
For large displacement hulls – Install near the centerline of the hull
and 1/3 of the way aft from the bow. Always install forward of the
propeller(s) and shaft(s).
For sailboats – Install forward of the leading edge of the keel, to one
side and near the centerline of the hull.

mm) from the inside of the hull. Before you drill the hole, be sure you
will be able to reach the large nut on the top of the unit, and that 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. (This
small hole can be filled easily if the mounting location is not suitable.)

(the “deadrise angle”) of more than 10°, you must include a mounting
block or “fairing.” The transducer must be mounted in a vertical
position. Attach the fairing block to the hull as firmly as possible. This
fairing block must be able to resist the drag of the water against the
hull, and must also be completely waterproof.

Installation Notes – In-Hull Transducer

Detailed instructions for this installation will be included with the trans­ducer. In this section, we will note just a few important points.

1. Choose the best mounting location:

For outboard powerboats – Install as far aft as possible
For inboard/outboard powerboats – Install close to the engine(s)
For inboard powerboats – Install forward of the propeller(s) and

shaft(s)
For sailboats – Install near the centerline of the hull and forward of
the leading edge of the keel

2. An

in-hull transducer may only be installed in a fiberglass hull which is

no more than 1" (25 mm) thick. The in-hull transducer may not be
installed in wood or aluminum hulls.

3. Use the standard in-hull transducer if it will be installed in a flat part of
the hull, or a section with no more than 10° of deadrise. Use the angled
in-hull transducer if the mounting location has up to a 22° of deadrise.

4. Do not try to compensate for the angle of the hull by fairing the epoxy
adhesive on the face of the transducer.

5. Use the epoxy supplied with the in-hull transducer, or an equivalent
epoxy glue. Do not use any other type of adhesive, including silicone
or RTV adhesive.

Installation Notes – Trolling Motor Transducer

Both Downlooker and Sidelooker transducers may be installed on a
trolling motor. See Fig. 2-8.

Detailed instructions for these installations will be included with the
transducer(s). The Downlooker transducer is mounted on the horizontal
gear case of the motor. The Sidelooker transducer is attached to the
vertical support tube. These installations are simple, but it is important to
keep these points in mind:

1. Keep the Sidelooker transducer fully submerged. The transducer will
only produce an image if it is immersed in water.

2. Keep the Sidelooker transducer clear of weeds or debris.

3. When the position of the trolling motor is changed, the field of view of
the Sidelooker also changes. The Sidelooker can be aimed at interest­ing echoes, but can also be positioned so that it is looking back at the
hull. Be aware of the position of the Sidelooker transducer.

Mounting the Display Unit – Standard Mount

You may mount the display unit on any flat surface using the bracket
supplied. See Fig. 2-9. (There is also an optional kit which allows you to
flush-mount the display in a flat panel or dashboard). Follow these
instructions if you are using the standard mounting bracket:

1. The “LCD” type display used on this unit is easier to see from certain
angles. Before selecting a permanent mounting location, make
temporary power connections and turn on the unit. This will allow you
to test the visibility of the display from several different angles.

2. Remove the display unit from the bracket by pressing on the large
button in the center of the bracket. See Fig. 2-9.

3. Mount the base of the bracket using the supplied screws.

4. Slide the display unit back into the bracket.

5. Adjust the display unit for the best viewing angle. You can turn the
display from side to side, and tilt it up or down.

Mounting the Display Unit – Flush Mount

In order to do this installation, you will need the optional flush mounting kit
(part no. M78931). See Fig. 2-11.

1. Select a mounting location on the dashboard or control panel.
Choose a clear, flat area at least 6" x 6" (152 mm x 152 mm). Be sure
you will also have at least 6" (152 mm) of clearance behind the area
where the display unit will be mounted. It is a good idea to drill a
small pilot hole in the center of the mounting area. Be sure there are
no hidden electrical wires or other items behind the point where you
plan to mount the display unit.

2. A mounting template is supplied with the flush mounting kit. Tape this
over the selected location on the panel and trace around the edges.

3. Make the cutout for the display. Drill a series of 1/2" (13 mm) holes at
the points shown around the edges of the cutout area.

holes for the cable, they must be large enough to accept the connector.
This will allow you to make the installation without cutting the wire.

1. Route the cable up and over the top edge of the transom. See Fig. 2-

13. 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 19 mm) through the transom for the cable. (Re­member
connector attached. Do not cut the cable!) To seal the opening, use
a feed-thru cap where the cable passes through the transom.

2. Run the cable through the interior of the boat. If the transducer cable
runs near another electrical wire, it may pick up electrical interference
or “noise.” To reduce this, try to keep the transducer cable separated

as far as possible from all other wires. This is especially important
with wiring for the boat’s ignition, alternator, or tachometer. Also try to
keep the transducer cable away from the antenna and power cables
for VHF or FM radios. It is also helpful to keep the transducer cable
away from the FishFinder power cable. If it is necessar y to r un the
transducer

cable across any wires, make the crossing at a right angle.

3. Be careful not to tear the cable jacket when passing it through
bulkheads and other parts of your boat. Secure the cables in place
using tywraps or lacing twine. Coil the extra cable and tie it out of the
way.

4. If the 20 foot (6 m) transducer cable is not long enough, a 15 foot
(4.6 m) extension cable is available from your Raymarine dealer (part
no. M99-140). 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.
Note: To extend both depth and Sidelooker cables, use the M99-139
extension cable.

5. At the rear of the display unit, plug in the transducer cable using the
keyed connector.

Making the DC Po wer Connections

1. The display unit is designed for use on boats with 12V DC power
systems. (The unit can operate as long as the DC voltage is between

11.0 and 16V DC.) The display unit can be wired to a negative­ground system, or both the negative and positive supply lines may be
“floating” above ground.

with positive ground.

2. The 5-foot power cable (1.5 m) supplied with the display unit should
reach the source of DC power. On a small boat, connect the power

Installation

leads directly to the main battery isolation switch or breaker. On a
larger boat, route the power leads to the DC power distribution panel.

3. It is very important that you connect the power leads correctly.
See Fig. 2-15. At the power source, connect the

positive

terminal (+), and the

black

wire to the

red

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.)

4. 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 2 amp in-line fuse.
(In-line fuses are available at most marine supply stores.)

5. To prevent any interference or electrical noise, separate the
FishFinder power wiring as much as possible from other devices.
Avoid running the FishFinder power wires near the power wiring for
any radar, radio, or Loran-C units. If possible, wire the FishFinder
power wires to a separate circuit breaker.

6. 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.

If you extend the power wiring, be sure all electrical connections are
solid and durable. Soldering is the best way to make these connec­tions. Insulate all connections using heat-shrink tubing or electrical
tape. You may also use crimp connectors or a terminal strip, but be
sure to use good-quality marine-grade parts.

7. At the rear of the display unit, plug in the power wires using the keyed
connector.

8. When you press the

PWR

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 t he p o la rity is not correct, reconnect the leads properly and
try again.

Final note: After you finish the installation, please remember to fill out the
Warranty Card included with this manual.

FishFinder
Page

A moment after you first turn on the display unit, the Lamp/Contrast menu
disappears. The unit then automatically switches to the FishFinder page.
Figure 3-4 shows a typical display. (The FishFinder page is also called the
“chart” or “bottom graph” display.) As time passes, this display scrolls from
right to left. The scrolling image becomes a record of the echoes and the
bottom seen by the FishFinder as your boat moves.

The images at the right side of the display show the most recent echoes.

28

Operating Instructions

Some of these echoes indicate fish, and others show the bottom. As new
echoes are received, the FishFinder “draws” a graph of the bottom. The
bottom graph helps you to tell whether the bottom is rising or falling. It
also allows you to identify the shape or “structure” of the bottom. This
can indicate a reef or shipwreck.

Notice that the scrolling speed of the display does not necessarily match
the speed of the boat. The scrolling speed of the display is called the
“chart speed.” You can adjust this using the “System Setup Display.” (See
Section 4.)

Many of the items on this display appear in the other modes. Since you are
likely to use the FishFinder page most often, we will explain all of these
items here.

any

of the automatic features are turned on, the “Auto”
indication will appear here. (These include the automatic
range, auto sensitivity, and auto zoom features.)

The “range” is the maximum depth the unit is set to
measure. When the auto range feature is on, the
FishFinder chooses the correct range setting automatically.

The transducer can use two frequencies - 50 kHz for wide
coverage, or 200 kHz for a detailed view. You can also set
the unit to use both frequencies at the same time (“dual
frequency”). (For more on this, see “Choosing the Fre­quency.”)

The “sensitivity” controls the ability of the unit to tell the
difference between echoes of different strengths. A higher
sensitivity setting makes it easier to see smaller fish, but
also may pick up background noise. When auto sensitivity
is on, the FishFinder chooses the correct sensitivity setting
automatically.

Operating Instructions

29

Auto zoom on (Z)

The “zoom” can be used to magnify the image from a small
section of the water below the boat. (This is used with the
Zoom display, which we will descr ibe in a moment.) When
the auto zoom feature is on, the FishFinder automatically
moves the zoom window up or down to track the bottom.

Fish symbol on

When the FishFinder sees a fish, it can show this by
displaying a fish symbol. When the fish symbol feature is
turned off, the FishFinder indicates a fish as an arch­shaped line on the display. For more information, see the
section on “Fish Indications.”

Boat symbol This symbol is always turned on. It indicates that the new

information appears at the right edge of the display, and the
older information moves toward the left.

Center of display

Water surface This symbol (“0”) shows the depth indicated by the top of

the display. Usually, this is the level of the surface of the
water. (If the Zoom feature is turned on, this will show the
depth of the top of the zoom area.) The depth is shown
using the same units as the rest of the display. This could
be feet (FT), fathoms (FA), or meters (M), depending on the
setting you make in the System Setup display.

Depth markers

These markers show depths between the surface and the
full depth range. In this example, the unit is set for a depth
range of 100 feet. This means that each of the depth
markers shows an interval of 20 feet.

Fish symbol This indicates that the FishFinder sees a fish. Generally,

the larger the fish symbol appears, the larger the fish. (The
size of the fish symbol actually depends on a number of
factors. See the section on “Fish Indications.”)

30

Operating Instructions

If the fish is detected using the narrow 200 kHz beam, the
display will show a filled-in symbol. If the fish is detected by
the

wide 50 kHz beam, the display will use a hollow symbol.

(For more on this, see “Choosing the Frequency.”)

Fish depth This indicates the depth of the fish shown by the fish

symbol. This number will be shown using the same depth
units (feet, fathoms, or meters) you have selected on the
System Setup display. The fish depth indicator is turned off
when the fish symbol function is off.

Bottom of display

Bottom indication

This shows the bottom of the lake or sea. You can com­pare this to the range depth shown in the lower right-hand
corner. (In this example, the checkered pattern shows the
unit is getting a strong echo return from the bottom. See
the information on the White Line feature in the Setup
Instructions.)

Range The “range” is the maximum depth the unit is set to

measure. In this example, this is 100 feet. You can set the
range manually, or the FishFinder can do it automatically.

Bottom depth This is the depth of the bottom shown on the display. You

can select FT (feet), FA (fathoms), or M (meters) using the
System Setup display. If the FishFinder can’t tell how deep
the water is, the last known depth flashes on the display.
This will continue until the unit can see the bottom again.

Buzzer symbol

This symbol shows whether any of the alarms will use the
buzzer. There are three kinds of alarms: shallow, deep, and
fish. If one of these alarms is set, it will always present a
flashing symbol on the display. The Buzzer symbol shows
whether the alarms will also use the buzzer.

If the Buzzer setting in the System Setup display is on
(indicating that the buzzer is enabled for all of the alarms),
this symbol will appear filled.

Operating Instructions

31

If the Buzzer setting is off (indicating that the buzzer is
disabled for all of the alarms), this symbol will be open.

Shallow alarm set

You can set an alar m to go off if the boat moves into water
which is shallower than a certain depth. If you set this type
of alarm, the “S” indicator will appear on the display. If the
alarm is triggered, the “S” symbol will flash. If the buzzer
has been turned on (in the System Setup display), the
buzzer will also sound. To stop the buzzer, press the
button. The “S” symbol will continue to flash until you move
into deeper water.

Deep alarm set

You can set a different alarm to go off if the boat moves into
water which is deeper than a certain depth. When this
alarm is set, the “D” symbol will appear. If the alarm is
triggered, the “D” symbol will flash. If the buzzer has been
turned on (in the System Setup display), the buzzer will
also sound. To stop the buzzer, press the

CLEAR

button. The
“D” symbol will continue to flash until you move into
shallower water.

Fish alarm set

The FishFinder also has an alarm which will sound when­ever it detects a fish. When this alarm is set, the fish
symbol appears at the bottom of the display. If the alarm is
triggered and the buzzer has been turned on (in the System
Setup display), the buzzer will sound for a moment.

Before we explain the other pages, there are some general things you
should know about the operation of the FishFinder.

CLEAR

Choosing a Frequency

We said that the FishFinder uses sound waves to “see” through the water
under the boat. The “frequency” is a measure of how fast the sound
waves change or “vibrate.” The FishFinder uses sound waves with two
different frequencies – 50 kHz and 200 kHz. Raymarine uses these two
frequencies because each is better for a particular purpose.

32

Operating Instructions

50 kHz frequency

• Scans a wide area

• Penetrates water well, good for deep water
200 kHz frequency

• Scans a narrower area, but produces a more detailed view

• Good for seeing fish near the bottom or fish close together

• Better for use in very shallow water
“Dual” frequency (both 50 kHz and 200 kHz at once)

• Has the advantages of both frequencies

• Good depth penetration

• Good detail in display

• Using the “Dual 50 kHz” setting, the display is produced using the
signal from the 50 kHz beam, with additional information from the 200
kHz beam.

• Using the “Dual 200 kHz” setting, the display is produced using the
signal from the 200 kHz beam, with additional information from the 50
kHz beam.

If you are using one of the dual frequency settings, you can get some
useful information from the fish symbols. If the fish is spotted by the
narrow 200 kHz beam, the fish symbol will be black or filled-in. If a fish is
detected by the wide 50 kHz beam, the symbol will be hollow.

Fish Indications

Even using advanced sonar technology, it is sometimes hard to detect a
fish in the water. The body of a fish is just a little more dense than the
surrounding water. There is really nothing very solid for the sound waves
to bounce off of. The FishFinder L265 is very good at telling the difference
between a fish and the surrounding water. In fact, Raymarine is the leader
in this technology.

When the FishFinder finds a fish, it can be indicated by a fish symbol on
the display. In general, a larger symbol means a larger fish. This rule is
not always true, though. Let’s say that there are two fish of the same size:
one is close to the surface, and the other is near the bottom. The fish
which is close to the surface will have a larger symbol. This is because
the fish which is closer returns more of the sound waves back to the
FishFinder.

Operating Instructions

33

Actually, the sound waves are usually reflected by the air sac near the
center of the fish, and not by the body of the fish. The size of this air sac
is different for different kinds of fish. This can also affect the size of the
fish symbols on the display. A fish with a large air sac will produce a large
fish symbol, while a fish with a small sac will produce a small symbol.

The

symbol also indicates which of the two frequencies was used to locate

the fish. If the fish was spotted by the wide 50 kHz beam, the symbol will
appear to be hollow. If the fish was detected by the narrow 200 kHz
beam, the symbol will be solid.

If the fish symbol feature is turned off, the FishFinder indicates fish in a
different way. See Fig. 3-5. An arch-shaped mark on the display usually
indicates a fish. Again, a larger arch usually indicates a larger fish.
Several arches together show a school of fish.

The return from a fish will have a different appearance, depending on the
frequency used. If a fish is spotted by the wide 50 kHZ beam, the arch will

be broad. When using the narrower 200 kHz beam, the same fish will
produce a narrower arch.

The shape of the arch is also affected by the speed of the boat. If you are
moving slowly, the arches tend to be longer. If the boat is moving more
quickly, the arches are short and peaked. If the boat is moving very fast, a
fish may be indicated by a single vertical line.

Bottom Indications

The bottom usually produces a strong echo, so it is easy for the
FishFinder to see a lot of detail. The FishFinder can indicate many
different kinds of bottom conditions. See Fig. 3-6. A hard bottom appears
as a thin line. A softer bottom or a bottom covered with seaweed will
produce a wide line, as the sound waves reflect from different layers of the
bottom. An uneven bottom which is covered with rocks or coral produces
a complex display like that shown in the last part of the Figure. The
bottom image is irregular, with long “tails” pointing upward. A wreck
produces a similar image.

When the White Line feature is turned on, the unit can display even more
information about the bottom. In Fig. 3-4, the FishFinder is getting a good

echo from the bottom, so the upper layer of the bottom is shown in a
checkerboard pattern.

Notice that the lower layer of the bottom is shown as a solid display. This
indicates a weaker echo. Sometimes this means that the upper layer of
the bottom is soft. Some of the sound waves may reach through this
layer, and may be reflected by a more solid layer below. It is also possible
that the sound waves are making
bouncing off of the bottom of the boat, then reflecting off the bottom again.
This can happen if the water is shallow, the bottom is hard, or the sensitiv­ity is set to a high value.

Zoom magnification

This indicates the amount of “zoom” or magnification. You
always set the amount of zoom manually, using one of the
functions on the Setup display. You can choose an x2 view
(double the normal display size), x4, x6 or x8 in the series
of setup screens. See Section 4. You must also select the
area or “window” of the water you want to zoom. See the
next item.

Zoom area When you turn on the zoom feature, it can only enlarge a

part of the FishFinder display. You must decide which part
you want to enlarge. As we said, the right side of the
display shows the normal FishFinder display. The vertical
line at the right edge of this display shows the area or
“window” of the water being enlarged.

When the FishFinder is set for auto zoom, it will choose the
zoom area automatically. The unit always chooses an area
of the water which includes the bottom. The unit then
moves this area up or down to keep the bottom in the
picture. The auto zoom feature is great for bottom fishing.

You may also set the zoom area manually. In the series of
setup screens, select manual zoom. (See Section 4.)
Once you are back to the zoom display, you can move the

zoom area up or down (using the

On the FishFinder display the bottom graph is “drawn” after the FishFinder
receives several echoes. This has the effect of showing a record of the
bottom contour. The A-scope displays raw sonar data directly from the
transducer beam. This gives you a “real time” image of fish and bottom
structure directly below the transducer. This function is very useful in
showing the strength of the echo returned from a fish. Stronger fish
echoes on the A-scope display will appear wider; weaker echoes appear
as narrow bands closer to the horizontal center of the A-scope image.

Operating Instructions

39

The left section of the A-Scope display shows a section of the normal
FishFinder display. All of the features are the same. The right section
shows the A-Scope image.

A-Scope image

This shows the beam of sound waves extending down from
the boat, and spreading as it moves through the water. Any
fish or objects which are positioned under the boat will
appear on the display. This is a “real time” display, so you
can see the fish symbols moving as the fish swim under the
boat.

Bottom coverage

This shows the diameter of the beam of sound waves
where it meets the bottom. This dimension will be shown
using the same units as the rest of the display – feet (FT),
fathoms (FA), or meters (M). If the unit is set at 200kHz
single frequency, the bottom coverage display will reflect
the narrow (16°) beam of the 200kHz frequency setting. All
other frequency selections (200kHz dual, 50kHz dual, and
50kHz single) use the wider (65°) beam for the bottom

The Sidelooker Page, like the FishFinder Page, displays a graph or chart.
The scrolling vertical dashed line represents the centerline of the boat. As
new Sidelooker echoes are received, the new information appears at the
top of the display, and older information moves towards the bottom. There
is no relationship between the chart speed of the FishFinder and the
speed of the boat. (The speed at which the display moves is set by the
entry for “chart speed” in the Setup Menu.)

When the Fish Symbol feature is turned off, any fish detected will appear
as vertical marks. These may be slightly arched towards the center of the
display. The unit can also be set to display fish symbols, but the normal
fish marks are usually more helpful. The Sidelooker transducer transmits
at the 200 kHz frequency. If the unit spots any fish while the Fish Symbol

feature is on, they will be indicated by solid fish symbols. (You can turn the
Fish Symbol feature on or off from the System Setup Menu. See Section 4.)

Underwater objects such as submerged tree stumps or rocks can also be
detected by the Sidelooker transducer. These objects usually appear as
thicker vertical targets. The Sidelooker sounding beam is transmitted very
close to the surface of the water. In rough or choppy water this turbulence
may appear on the Sidelooker display as “noise” or “clutter.” The Side­looker will also display noise or clutter when your boat travels at high
speeds or in very shallow water. For best results, use the Sidelooker at
idle or slow trolling speeds.

Here are the special items on this display:
Boat symbol This is pointing forward on the screen to indicate that, on

the Sidelooker Page, the view is from above, as seen from
a bird’s-eye. The boat symbol appears at the top center of
the Sidelooker View.

Fish echo mark

A line or arch-shaped mark shows that the unit has detected
a fish. In general, a larger mark indicates a larger fish. If the
fish symbols are turned on, the unit will indicate fish using
symbols instead. A number beside each symbol shows the
distance from the boat to the fish. Remember that this
distance is measured

Bottom/Shore
Indication This indicates the area where the transducer beam is start-

ing to see the bottom, shore, or some other object. Again,
remember that the beam is looking sideways, so this could
really represent the bank of a stream or structure under a
dock or pier.

Depth This is the depth directly below the boat. Even when the

Sidelooker feature is turned on, the downward-looking
transducer is still used to measure the depth.

The Sidelooker feature has settings for Range and Sensitivity which are
separate from the Range and Sensitivity settings used for the standard
FishFinder Page. See Section 4 for details.

Sensitivity Setting

Fig. 4-3

Sensitivity
Setting

The sensitivity adjusts the ability of the unit to tell the differences between
echoes of different strengths. In general, the sensitivity should be as high
as possible, to detect the fish and show the detail on the bottom. How­ever, if the sensitivity is too high, the unit will begin to see bubbles in the
water, debris, and other “background noise.” Use a higher sensitivity
setting for deeper water, and a lower setting for shallower water.

If you adjust the sensitivity while you are looking at the Sidelooker display,
this will affect the sensitivity for the Sidelooker feature only.

From the menu item for the range setting, press the
control pad. The next menu item will allow you to set the sensitivity. See
Fig. 4-3. Use the < and > arrows on the Page control pad to select Auto or

Auto sensitivity

The FishFinder can be set to select the sensitivity by itself,
automatically. The unit chooses the sensitivity setting
which will detect fish, but will also show a minimum of
background noise. If the amount of back ground noise
changes (due to changing depth or water conditions), the
FishFinder will change the sensitivity to adjust. (You can
adjust the sensitivity of the unit while it is using Auto
sensitivity. Once Auto sensitivity is selected, use

Chart Speed Setting

Most of the displays on the FishFinder show a record of the signals the
unit has received. The new information appears at the right (or top) edge
of the display. The older information moves toward the left (or bottom) of
the display. The chart speed adjustment sets the speed at which the
display moves. (Notice that the scrolling speed of the display is not
related to the speed of the boat over the bottom. The speed of the display
is controlled

Figure 4-4 shows how the chart speed setting affects the display. In both
cases, the unit is showing the same section of the bottom. Using a faster

Frequency Setting

“Frequency” is a measure of how fast the sound waves change or
“vibrate.” This unit uses sound waves with two different frequencies – 50
kHz and 200 kHz. For an explanation on the uses of these two frequen­cies, see the section on “Choosing a Frequency.”

From the area of the display for the zoom settings, press the< arrow on
the Page control pad. The next menu item will allow you to make the
frequency setting. See Fig. 4-7.

Frequency
Setting

Frequency Use the < and > arrows on the Page control pad to make

your choice.

You have four choices here:

• 200 kHz, single frequency – The unit will use the narrow 200 kHz
beam. The fish symbols will be solid.

• 50 kHz, single frequency – The unit will use the wider 50 kHz beam.
The fish symbols will be hollow.

• 200 kHz, dual frequency – The unit will use both frequencies, but the
image on the display will be generated using the information from the
narrow 200 kHz beam.

• 50 kHz dual frequency – The unit will use both frequencies, but the
image on the display will be generated using the information from the
wider 50 kHz beam.

52

Setup Instructions

If you are using one of the dual frequency choices, some of the fish may
be revealed by one beam, but not the other. If a fish is detected by the
narrow 200 kHz beam, the symbol for that fish will appear solid. Any fish
which are detected by the wider 50 kHz beam will have fish symbols
which are hollow.

Once you have moved to the correct line, press the < or > arrows on the
Page control pad to change the entry. When you leave the display, the
unit will store any changes you have made.

Simulator This unit has a built-in simulator. When the simulator is

enabled, it presents a realistic display. You can use this
display to learn about the features of the unit without
operating your boat. The information on this display is
generated by the unit itself, and does not come from a
transducer. When this mode is turned on, you will see the
word “Simulation” flashing on the display.

Fish symbol When the unit detects a fish, it can show this using a fish

symbol. A number above the symbol shows the depth of the
fish. The size of the symbol is related to the size of the fish.
In general, the larger the symbol, the larger the fish. (For
more information, see the section on “Fish Indications.”)

When the fish symbol is turned off, the unit indicates a fish
by showing an arch-shaped line. See Fig. 3-5. This kind of
display does not include the depth readings for the fish.

White line This feature controls the way the unit displays strong and

weak echoes. When the white line feature is turned off, all

54

Setup Instructions

of the echoes are displayed in black. When the feature is
turned on, strong echoes are displayed using a crosshatch
(or “checkerboard”) pattern. A weaker return is shown
using a solid area of black or gray.

This feature helps to show the difference between the
strong echo from the bottom and the weaker echoes from
fish or weeds near the bottom.

Sidelooker This item is used with the optional “Sidelooker” transducer.

This type of transducer sends sound waves out to the sides
of the boat. See Fig. 3-10. If you have installed this
transducer, use this line of the display to turn on the
Sidelooker mode.

Shallow Alarm You can set an alarm to trigger whenever the boat moves into

water which is shallower than a limit you set. Use the

<

controls to move to the line for Shallow Alarm and use the

<

you do this, the display will ask which depth you want to use
as a limit. Use the < and > controls to set the limit you want.
To tur n this feature off, press the < control until the display
indicates zero feet, fathoms or meters.

When the shallow alarm is set, the letter “S” will appear in
the lower left-hand corner of the normal displays. If you
move into shallow water and trigger the alarm, the letter “S”
will begin to flash, and the buzzer will sound. Press the

CLEAR

button to silence the buzzer. The letter “S” will

continue to flash until you move into deeper water.

Deep Alarm An alar m can be set to trigger whenever the boat moves

into water which is deeper than a preset limit. Use the
and< controls to move to the line for Deep Alarm and use
the > control to turn this item on. Once you do this, the
display will ask which depth you want to use as a limit. Use
the < and > controls to set the limit you want. To turn this

into deep water and trigger the alarm, the letter “D” will
begin to flash, and the buzzer will sound. Press the
button to silence the buzzer. The letter “D” will continue to
flash until you move into shallower water.

Note: You may want to use both the Shallow Alarm and
Deep Alarm features when you are anchored. Set the limits
just a bit to either side of your anchor depth. When set this
way, the unit will trigger an alar m if the anchor drags and
the boat moves into shallower or deeper water.

Fish Alarm This unit has an alar m which will trigger when the unit

detects a fish. Use the < and > controls to turn this item on
or off. The fish alarm feature will work even if the fish
symbols are turned off.

When the fish alarm is set, the fish symbol will appear in the
lower left-hand corner of the normal displays.

Buzzer A buzzer can be set to sound when any of the alarm

conditions occurs (shallow, deep, or fish alarm). For the
shallow or deep alarms, the “S” or “D” symbol at the bottom
of the screen flashes. By pressing the

5 – Maintenance and Troubleshooting

Periodically check the display unit, cable, and transducer. Be sure all
components are free of corrosion and are securely mounted. Check all
cables for signs of chafing or abrasion. Be sure all of the connections to
the boat’s DC power and ground system are clean and tight.

Cleaning Instructions

Always keep the display unit clean. Use a soft, clean cloth to wipe off the
display panel. Do not use abrasive cleansers, chemical cleaners or
solvents. Use a glass cleaner or a suitable general-purpose detergent.

If you operate your boat in salt water, you will have to protect the hull with
antifouling paint. Use caution when sanding or cleaning the outside of the
hull near the transducer. Harsh cleaning solvents such as acetone may
damage the transducer.

Sea growth can collect quickly on the bottom of the transducer. This can
reduce the performance in just a few weeks. To prevent this, coat the
bottom of the transducer with a thin layer of paint. Use only a water-based
antifouling
ers. Apply it with a brush.

If your transducer becomes fouled or stops working because of sand or
sea growth, use a stiff brush to clean it. You may sand the surface with a
fine-grit wet or dry sandpaper (#320 grade or finer), but this will affect the
performance of the unit when the boat is moving at higher speeds.

Troubleshooting Suggestions

If the unit is not working correctly, there may be a simple cause. Before
you call for service help, please check these points:

The FishFinder display unit will not turn on –

1. The unit may actually be operating, but the contrast may have been
set to the “full light” or “full dark” setting. Turn on the unit by pressing

PWR

the
the factory defaults. See the default settings on page 59.

2. If the power wiring includes a fuse, it may be blown. Also check the
circuit breaker or main battery switch.

60

and

CLEAR

buttons at the same time to change all settings to

Maintenance and Troubleshooting

3. You may have reversed the power connections. Follow the DC power
lines all the way back to the battery. The red wire should connect to
the positive terminal (+) on the battery or power source, and the black
wire should connect to the negative terminal (-) (also called “ground”
or “earth”). If the polarity is not correct, reconnect the leads properly
and check again.

4. The battery or DC power source may not be producing the correct
voltage. The FishFinder needs at least 11 volts to operate. If the
voltage is lower, check for loose or corroded connections, or a
problem with the power source.

The display unit “freezes” (temporarily or permanently) –

1. Check that the display has not been stopped using the Chart Speed
setting. (If the adjustment bar is moved all of the way to the left, the
display will freeze.)

2. A source of electrical “noise” may be interfering with the unit’s
operation. Both the transducer cable and the power cable for the
FishFinder
the boat.
To locate the source of the noise, turn on the FishFinder. Next, turn
on each electrical device on the boat, but just supply power to one
device at a time. This may reveal the cause of the problem. Move
the FishFinder, the other unit, or the wiring. A movement of just a few
inches can make a big difference. If it is necessary to cross any
wires, make the crossing at a right angle.
Start the motor in neutral and increase the RPM speed. This can
reveal a problem with the wiring for the boat’s ignition, alternator, or
tachometer. It may help to use resistor-type spark plugs or spark plug
cables on the boat’s motor. You can also tr y a noise-suppression filter
on the alternator.

3. One of the wiring connections may be loose. All of the connections
should be clean, tight, and insulated. Soldering is the best way of
making these connections. Protect each connection with a piece of
shrink-wrap tubing.

4. The transducer cable may be damaged. Check for any point where
the wiring may be pinched or bent. Look for signs that water has
gotten into the cable. If the transducer cable is damaged, the

should be routed as far as possible from all other wiring on

Maintenance and Troubleshooting

61

transducer and cable should be replaced as a unit. Contact
Raymarine for instructions.

The display unit does not see the bottom or fish –

1. Be sure the display unit is not using the Simulation mode. (If this is
the case, the word “Simulation” will flash on the display.)

2. On a unit with the transom-mount transducer, the transducer may
have “kicked up” because it hit an obstruction. See Fig. 2-4. Move
the transducer down into the working position.

3. The unit may be set for Manual sensitivity, and be using a very low
sensitivity

on the unit by pressing the

setting. To reset all of the values to the factor y defaults, turn

PWR

and

CLEAR

buttons at the same time.

See the default settings on page 59.

4. The transducer may not be vertical. Be sure that the transducer is
aiming straight down, or within 10° of vertical.

5. If the transducer is an in-hull type, be sure that it is installed correctly.
The transducer should be “looking” through just one layer of fiber­glass hull material, no more than 1" (25 mm) thick. The transducer
should be firmly attached to the hull using the correct type of adhe­sive/sealant.

6. The face of the transducer may be covered or fouled. Use a stiff
brush to clean it. You may also sand the surface with a fine-grit wet
or dry sandpaper (#320 grade or finer), but this will affect the perfor­mance of the unit when the boat is moving at higher speeds.

7. If the FishFinder is using the Auto Sensitivity setting, it may be
reacting to an increase in electrical “noise.” As the level of noise
increases, the sensitivity automatically adjusts, and the unit can lose
its ability to see the bottom or fish. Check for problems with the wiring
as described in the section on “Display unit freezes.”

8. The voltage from the power source may be low. This affects the
transmitting power of the FishFinder. Check the connections as
described in the section on “The display unit freezes.”

The FishFinder does not display fish arches –

1. Be sure the Fish Symbol feature is turned off. See the instructions for
the System Setup display.

2. The FishFinder will not display arches unless the boat is moving. If
the boat is stopped, fish will appear on the display as straight lines.

62

Maintenance and Troubleshooting

3. The transducer may not be aimed straight down. In order to display
complete arches, the transducer must be vertical.

4. The sensitivity setting may not be high enough. Go to the Setup
Menu, choose Manual Sensitivity, and increase the sensitivity.

The display disappears or is unreliable when the boat is moving at
high speeds –

1. Increased turbulence around the transducer may be “confusing” the
unit. Move the transducer to a location where there is less turbulence
when the boat is moving.

2. If the FishFinder is using the Auto Sensitivity setting, it may be
reacting to an increase in electrical “noise.” As the level of noise
increases, the sensitivity automatically adjusts, and the unit can lose
its ability to see the bottom or fish. Check for problems with the wiring
as described in the section on “The display unit freezes.”

The display unit shows lots of background “noise” –

1. The unit may be set to use the manual sensitivity adjustment, and the
sensitivity may be set too high. See the information on “Setup
Instructions.”

2. The transducer may be mounted incorrectly, or may be fouled. Check
the mounting as described in Section 2. Clean the transducer as
described earlier in this section.

The depth setting flashes often –

Note: Normally, this indicates that the bottom has moved out of range.

1. The transducer may not be installed correctly, or the signal may not
be reaching the display unit. Recheck the instructions in “Mounting
the T r ansducer” in Section 2. Check the transducer cable for signs of
damage. If the cable is damaged, the transducer and cable should be
replaced as a unit.

2. The voltage reaching the unit may be low, and this may be affecting
the transmitting power. Check for problems with the wiring as
described in the section on “The display unit freezes.”

Glossar y of Terms

Aft: Near or toward the rear part of the boat (nautical term).
Background noise: False or meaningless echo returns produced by

bubbles, water turbulence, or debris

Bow: The front of the boat (nautical term).
Cavitation: Air bubbles in the water which affect the readings of a

transducer. These are normally caused by mounting the transducer
at an incorrect angle or location.

Chart Speed: The rate at which echoes scroll across the display.
Cursor: On a setup display, the place where the unit is ready to make a

change or enter new information. This point is highlighted. You can
move up or down the list or display using the

Deadrise angle: The slope or angle of the underside of the hull, mea-

sured in the side-to-side direction.

Default value: A value or setting which is pre-loaded into the unit at the

factory.

Fairing block: A block used when mounting a thru-hull transducer. The

fairing block shims the transducer to align it on a perfect horizontal
plane versus the rise of the hull.

Fathom: A unit of depth equal to 6 feet.
Frequency: The rate at which a sound source vibrates, or the rate at

which a sound wave changes.

Fore: Near or toward the front part of the boat (nautical term).
Keel: The center of the hull, running from the bow to the stern.
kHz: “Kilo-Hertz” – a measure of frequency (For example, 200 kHz =

200,000 oscillations per second.)

Kick-up bracket: A bracket which is installed on the transom of a boat

and holds the transducer in place. When the transducer strikes an
obstruction, it is designed to release or “kick up” out of the water to
prevent any damage.

<

Knot: One nautical mile per hour (1.15 statute miles per hour).
LCD: “Liquid Crystal Display” - A technology used to produce flat-panel

displays.

Nautical mile: 6076 feet
Port: Left side of the boat, when facing the bow (nautical term).
PVDF: “Poly Vinylidene Fluoride” – A unique polymer plastic that has the

ability to convert sound waves into electrical impulses. PVDF is used
in the optional Sidelooker transducer for excellent detection of fish in
the horizontal direction.

Range: The depth scale for the unit. The maximum distance the unit will

be able to see at a particular range setting.

Sensitivity: The ability of a receiver to distinguish between echoes of

different strengths. In general, use a higher sensitivity setting for
deep water, and a lower setting for shallow water.

Starboard: Right side of the boat, when facing the bow (nautical term).
Statute mile: 5280 ft.
Stern: The rear of a boat (nautical term).
Thermocline: A level in the water where two areas of differing water

temperature meet. Sometimes a thermocline can reflect sonar waves
and present a false display.

Transducer: A device which sends and receives high frequency sound

waves through the water.

Transom: The rear-most part of the boat’s hull, often a flat panel.
White Line: A feature used to help display fish near the bottom. This

feature helps to show the difference between weak returns (including
fish near the bottom) and strong returns (including the bottom itself).

Zoom: A way of magnifying or enlarging part of the display to give a

better view of a section of the water.
