FISH 4432/4433 Installation and Operation Manual5

1 Introduction

Congratulations on choosing a Navman
fish-finder. For maximum benefit, please read this
manual carefully before installation and use.

This manual describes how to install and set
up the FISH 4432/4433 and the associated
dual-frequency transom transducer. (If a through
hull transducer is used, refer to the Installation
Instructions supplied with that transducer.)

This manual also explains how to operate
the FISH 4432/4433 effectively and provides
troubleshooting information and performance tips.

1-1 Benefits of the FISH 4432/4433

The FISH 4432/4 433 is a high quality, dual­frequency sonar fishf inder that is supplied
with a dual-frequency transducer. It uses a 16
level greyscale FSTN display for easy daylight
viewing that can be dimmed for night fishing.
The bracket mounting option also allows
the fishfinder to be tilted and swivelled for
optimum viewing.

The dual frequenc y capability enables the
FISH 4432/4433 to operate and display:

• At a high frequency of 200 kHz.

• At a low frequency of 83 kHz.

• Both frequencies side-by-side on a split
display.

• Both frequencies combined together into a
single display.

This capability, combined with a variable power
output of up to 250 watts, ensures that the FISH
4432/4433 operates effectively in shallow and
deep water.

The FISH 4432/4433 can detect the bottom to
a depth of 750 feet (230 metres) depending
on the clarity of the water, the ultrasonic
frequency chosen and the type of transducer
used.

The Navman fishfinder can be used to find
fish, to locate features on the bottom such as
reefs or wrecks and to help recognize favourite
fishing spots from the bottom profile.

The Navman fishfinder can also assist with
navigation by providing depth information to

Important

It is vital to the performance of the fishf inder
that the transducer is installed in the best
location. Please follow the installation
instructions very carefully.

help identify the depth contours marked on
charts. The FISH 4 432/4433 is par ticularly suited
to work with the TRACKER 5430/5380.

The two instruments can be connected
together using either NavBus or NMEA, so they
can share data. (only applies to FISH 4433)

IMPOR TANT NOTE ON USE. While any
fishfinder can be used as an aid to navigation,
accuracy can be limited by many fac tors,
including the location of the transducer. It is
the user’s responsibility to ensure the Navman
fishfinder is installed and used correctly.

With the optional fuel kit, the FISH 4433 also
becomes a sophisticated and easy-to- use
fuel computer.

All of the Navman 4000 Series f ishfinders use
new proprietary SBN-II Technology for sonar
processing to improve Signal enhancement,
Bottom recognition and Noise rejection.

SBN-II Technology uses digital adaptive filter
algorithms to enhance all returned signals. At
the same time, SBN-II Technology uses active
noise control to reject interference, which
can often be mistaken by fishf inders for true
returns.

Using SBN-II Technology, the Navman
fishf inder analyses the reflections from each
pulse, filters false returns and displays what is
in the water under the boat. See section 4-1
Interpreting the display, for more information.

1-2 How the FISH 4432/4433 works

The FISH 4432/4 433 has two par ts:

- the transducer attached to the hull

- the display unit.

The transducer generates an ultrasonic pulse
(sound that is above the hearing range of
the human ear), which travels down towards
the bottom at a speed of about 4800 ft/sec
(1463 m/sec), spreading out into a cone shape.

When the pulse meets an objec t, such as a
fish or the bottom, it is partly reflected back
up towards the boat as an echo. The depth
of the object or bot tom is calculated by the
FISH 4432/4433 by measuring the time taken
between sending a pulse and receiving the
echo. When an echo has been returned, the
next pulse is sent.

The FISH 4432/4 433 converts each echo into
an electronic signal, displayed as a vertical

Scroll speed

Use this to set the scroll speed on the display.
There is a choice of: Very Fast, Fast,
Medium, Slow and Pause. The depth of the
water also af fects the speed of the display.

Faster scroll speeds combined with a slow
boat speed (typically between 2 and 6 knots)
shows the most fish detail. Medium or Slow
scroll speeds result in sonar information being
displayed over a longer period, but with less
detail. See Section 4-1 Interpreting the display,
for more information.

Fish symbols

These appear only in the main sonar displays.
Fish symbols can be shown in three ways:

• As a fish symbol (Sy m bol).

• As a fish symbol with the depth

(Sym bol+ dept h). The depth is shown
beside the fish symbol.

• As a depth (Depth). The depth is shown
above where the fish was detected

• Switched off (Off) so that echoes are not
converted to f ish symbols but are displayed
directly.

See section 4-3 Fish detection and display, for
more information about fish symbols.

Fish sensitivity

Use this func tion to adjust the minimum fish
detection level. Select Low to reject noise and
small fish. Selec t High to detect maximum
number of f ish.

Digit size

Use this to remove or change the size of the
depth display on the sonar displays. There is a

Tan k ful l

Select Tank full each time the fuel tank(s)
are completely refilled. When asked Are you
sure? select Yes. Otherwise, the reading on
the Fuel display (see section 5-6 Fuel Display)
and the Low Fuel Alarm (see section
3 -5 Setup > Alarms) are meaningless.

Set remaining

Before doing a partial refill of the tank or
removing fuel manually from the tank (for
example, by siphoning it off):

1. No te the Remaining reading on the
Fuel display.

2. Note how much fuel is added or removed.

3. Calculate how much fuel is now in the tank.

4. Select Set remaining and update
the reading.

NAVMAN

It is essential to do this whenever some fuel is
added or removed. Otherwise, the reading on
the Fuel display (see section 5-6 Fuel Display)
and the Low Fuel Alarm (see section
3-5 Setup > Alarms) are meaningless.

Clear used

Select Clear used to set Use d (the
amount of fuel used) to zero. Do this to start
measuring the amount of fuel used over a
certain time or distance.
When asked A re you sure? select Yes.

Tank size

Enter the capacity of the fuel tank.

Flow filter

Most engines do not draw fuel from the tank at
a steady rate. To give a stable fuel flow reading,
the fishfinder calculates the flow value(s) by
taking several measurements and averaging
them. Use the Flow filter to set the period over
which the fuel flow is averaged.

The Flow filter can be set from 0 to 30 seconds.
Use the lowest value which gives a stable flow.
Usually a value of 5 to 10 seconds will give a
satisfactory result for two-stroke carburettor
engines. Fuel injec ted or four-stroke engines
may require a larger value.

3-4 Setup > Logs

Press MENU one or more times until the Setup
menu is displayed, then selec t Logs:

This setting affects the Fuel flow and Fuel
economy reading on the Fuel display (see
section 5-6 Fuel display) but it does not affec t

Fuel

Warning:

Extreme precautions must be
observed when carrying out this
procedure.
Failure to do so could create
hazardous conditions that can
cause serious personal or
property damage.

Calibrating the fuel usage can improve the
accuracy of fuel measurements.

Twin engine installations require each fuel
transducer to be calibrated. This can be done
at the same time with two portable tanks or at
different times using one portable tank.

Calibrating the fuel transducer(s) requires
accurate measurement of the fuel
consumption. This is best done using a small
portable tank. At least 4 gallons (15 litres) of
fuel should be used to ensure an accurate
calibration.

It is often very dif ficult to fill underfloor tank s
to the same level twice due to air pockets, so
the more fuel used, the more accurate the
calibration.

To calibrate the fuel transducer(s), perform the
following steps:

1. Record the level of the fuel in the tank(s).

2. Connect the p ortable tank(s) to the engine

through the fuel transducer(s).

3. Run the engine at normal cruising speed

until at least 4 gallons (15 litres) of fuel has
been used per engine.

4. Check the actual amount of fuel used per

engine by refilling the portable tank (s) to
the original level and noting the reading(s)
from the fuel dispenser’s gauge.

5. Select Fuel. Use the cursor keys to change

the reading for each engine to match that
on the fuel dispenser’s gauge.

6. Press ENT when the reading is correct.

Note: If the fuel calibration options appear
to give erroneous readings after a while,
first check that the fuel sensor has been
installed correctly according to the installation
instruc tions supplied with it. Then see
Appendix B - Troubleshooting.

Keel of fset

Keel offset is a depth correction representing
the vertical distance between the depth
transducer and the location from which the

depth is to be measured.

Enter a positive keel offset value when the
transducer is located below the water surface
but the total depth is required.

Enter a negative keel offset value when the
depth below the deepest par t of the boat is
required (such as the keel, the rudder or the
propeller) and the transducer is located closer
to the water sur face.

4 Using the FISH 4432/4433

This section explains how to interpret the sonar
displays, when and why to use the different
frequencies and how f ish are detected
and displayed.

4-1 Interpreting the display

The sonar displays do not show a fixed distance
travelled by the boat; rather, they display a
history, showing what has passed b elow the
boat during a certain period of time.

The history of the sonar signal displayed
depends on the depth of the water and the
scroll speed setting.

In shallow water, the echoes have a short
distance to travel between the bottom and the
boat. In deep water, the history moves across
the display more slowly because the echoes
take longer to travel bet ween the bottom and
the boat. For example, when the scroll speed is
set to Fast, at depths over 600ft it takes about

2.5 minutes for each vertical line of pixels to
move across the display, whereas at 20ft it
takes only about 4-5 seconds.

The scroll speed can be set by the user to
display either a longer histor y with less fish
information or a shor ter history with more fish
details. See sec tion 3-2 Setup > Sonar.

If the boat is anchored, the echoes all come
from the same area of bottom. This produces a
flat bot tom trace on the display.

The screen shot shows a typical sonar display
with the Fish symbols turned Off.

It also describes Gain and Range and shows
examples of some of the different sonar
displays. Also see section 1-2 How the FISH
4432/4433 works.

Strengt h of echoes

The colors indicate differences in the strength
of the echo. The strength varies with several
factors, such as the:

• Size of the fish, school of fish or other object.

• Depth of the f ish or object.

• Location of the fish or object. (The area

covered by the ultrasonic pulse is a rough
cone shape and the echoes are strongest in
the middle.)

• Clarity of water. Particles or air in the water

reduce the strength of the echo.

• Composition or density of the object or

bottom.

Note: Planing h ulls at speed produce ai r bubbles
and turbul ent water that bombard the trans ducer.
The resulting u ltrasonic noise may be picke d up by
the transducer and obscure the real echoes.

Soft bottoms
such as mud,
weed and
sand show
as narrow
bands

Hard bottoms
such as rock
or coral
show as wide
bands

Bottom types

Mud, weed and sandy bottoms tend to weaken
and scatter the sonar pulse, resulting in a weak
echo. Hard, rocky or coral bottoms reflect the
pulse, resulting in a strong echo. See section
5-3 Sonar Bottom display.

NAVMAN

FISH 4432/4433 Installation and Operation Manual17

Frequenc y and cone width

The pulse generated by the FISH 4432/4433
transducer travels down through the water,
spreading outwards to form a rough cone shape.
However, the cone width is dependent upon
the frequency of the pulse; at 83 kHz it is 20°,
whereas at 200 kHz it is 14°. The chart shows
how the cone width varies over depth for each
frequency used. Figures are approximate.

The differences in the cone width affect what is displayed. See section 4-2 Single and Dual Frequency fishfinding.

Shadows

Shadows are created around areas where the ultrasonic beam cannot ‘see’. These areas include
hollows on the bottom or beside rocks and ledges, where the strong echoes returned off the rocks
obscure the weak echoes of the fish and may also create a double bottom trace. See following for
an example of the sonar display in such an environment. A double bottom trace is shown on the
display.

When looking for f ish with the wide angled 83 kHz frequency, be aware of increased shadows. Use
the high frequency 200 kHz in areas that have rocks and ledges because this frequenc y reduces the
shadow effect considerably.

4-3 Fish detec tion and display

Where to find fis h

Underwater features like reefs, wrecks and
rocky outcrops attract fish. Use the 83/20 0
kHz frequency display to find these features,
then look for fish by passing over the feature
slowly several times using the Zoom display
(see section 5-2 Sonar Zoom display). If there
is a current, the fish will often be found
downstream of the feature.

When fishing with the FISH 4432/4433 with
the Fish symbols Off, a weak fuz zy band
may a ppear betwee n the bottom trace an d
surfa ce. This might indicate a thermoc line - a
rapid chan ge in water temperature , such as the
edge of a war m or cold current. The te mperature
diffe rence can form a barr ier which the fish may
not swim through. In fre sh water, fish often
collec t around a thermocli ne.

Fish symbols

The fish symbol can be customized or switched off
altogether so that the echoes are not converted to
fish symbols on the display. See section 3-2 Setup
> Sonar. The differences between Fish symbol On
and Off are:

Fish symbols On

Using Navman’s SBN -II sonar technology the
fishfinder analyses all echoes and eliminates most
false signals and clutter so that remaining targets
are most likely fish. Depending on the strength
of the remaining echoes, they are displayed as
either small, medium or large fish symbols - with
or without depth. While the SBN -II processing is
very sophisticated it is not foolproof - the re will
be times wh en
the fishfinder
will not be a ble

bubble s, rubbish
containing air,
fishin g floats etc.
and genui ne fish.

The pic ture shows
the Sonar d isplay
with the Fish
symbol: symbol
+ depth:

Fish symbols Off

For experienced users this always provides the
best information as every echo is displayed,
whether it is surface clutter, a thermocline or
a fish.

The picture in section 4-1 Interpreting the
display, shows the Sonar display with the Fish
symbols Off. The fish appear as arches.

Fish arches

In good conditions and with Fish symbols
Off, a fish passing through the cone-shaped
ultrasonic pulse is displayed as a fish arch. The
83 kHz frequency uses a wider cone than the
200 kHz frequency. This makes the f ish arches
easier to see.

A fish arch occurs when a f ish enters the weak
edge of the sonar cone, generating a weak
echo that is displayed as the first pixel of
the fish arch. As the fish moves closer to the
middle of the cone, the distance between the
transducer and the fish reduces and the echo
is displayed at progressively shallower depths,
producing the star t of an arch. When the fish
passes directly beneath the middle of the cone,
the echo becomes strongest and thickest. As
the fish passes out of the middle of the cone
the reverse happens with a progressively
weaker and deeper echo.

There are many reasons why fish arches may
not be seen. For example:

• Poor transducer installation (see Tran som

Transducers Installa tion Guide).

• If the boat is anchored then fish will tend

to show on the display as horizontal lines
as they swim into and out of the transducer
sonar beam. Slow speeds in deeper water
give the best fish arch returns.

• Range is important. It will be much easier

to see fish arches when using zoom mode
to concentrate on a particular sec tion
of water, rather than just displaying
every thing from the surface to the bot tom.
Zooming increases screen resolution and is
necessar y for good fish arches.

NAVMAN

FISH 4432/4433 Installation and Operation Manual21

• It is difficult to get fish arches in shallow water as the transducer sonar beam is very narrow near

the surface and fish do not stay within the beam long enough to display an arch. Several fish in
shallow water tend to display as randomly stacked blocks of pixels.

• Wave motion may result in distorted fish arches

4-4 Gain

Gain (sensitivity) controls the amount of
detail displayed on the FISH 4432/4 433.
Understanding how to set suitable
Gain settings is important for optimum
performance.

The Navman fishfinder has three gain modes,
Cruising, Fishing and Manual.

• Cruising Mode
Use this mode to show only the bottom and
large fish.

• Fishing Mode
Use this mode to show as much detail as
possible.

• Manual Mode
The gain can be adjusted by the user to
compensate for water depth and clarity.

High Gain settings may amplif y the normal
background noise until it appears as random
pixels.

Note: The Gain mode a utomatically changes to
Manual Gai n if the gain or threshold sett ings are
adjusted by th e user.

Obtaining the best results

To obtain the best detection capability for both
fish and bottom we recommend the use of the
Sonar A-Scope display:

1. Set the threshold to 0% .

2. Adjust the gain until the threshold line is
just to the right of the unwanted noise.

4-5 Range

Range is the vertical depth displayed on the
FISH 4432/4 433.

The Navman fishfinder has two range modes,
Auto Range and Manual Range:

• In Auto Range, the f ishfinder adjusts

the depth range automatically so the
bottom is always shown in the lower part
of the display. The use of Auto Range is
recommended for normal conditions.

• In Manual Range, the fishfinder shows only

a selected depth range. In areas of rapidly
changing b ottom depth, such as the sea
floor around pinnacles, it can be useful
to prevent the display from rescaling to
always show the bottom. If the bottom is
deeper than the specified depth range, it
will not be shown on the display.

Changin g the Range Mode

Press the + or - key to change to Manual Range
mode and to increase or decrease the range to
the desired depth. Values can be set between
10 ft. (3 m) to 1000 f t. (300 m).

To change from the current mode:

1. From any Sonar display, press MENU to
display the Options menu.

2. Highlight Range, then use the cursor keys

Fish recognition

The echo strengths shown on the A-scope
can be useful in recognising the t ype of fish.
Different species of fish have different sizes
and shapes of swim bladders. The air in the
swim bladder reflects the ultrasonic pulse, so
the strength of the echo varies between fish
species according to the size and shape of the
swim bladder.

The strength of echoes on this view are
determined by the’height’ of the echo shown
on the screen.

When fishing among a school of fish and
catching them, note the fish species and the
strength of the echo that it returns on the
A-scope. Then, when that par ticular echo is
seen at future times on the fishf inder, it is likely
to be the same fish species.

1. Cut a hole in the bulkhead for the display
unit using the flush mount template.

2. Drill four holes for the mounting studs
using the flush mount template.

3. Screw the four studs into the brass inser ts
in the back of the display unit.

4. Sit the display unit in place and fit the
washers and nuts to the studs.

Bracket Mounting

1. Fix the mounting bracket onto the boat
using the three stainless steel screws. Do not
overtighten the screws, as the bracket may
not rotate.

2. Push the display unit onto the mounting
bracket and tighten it firmly using the knob
on the mounting bracket.

3. Attach the cables.

6-4 Systems of severa l instruments (4433 0nly)

Several Navman instruments can be connected
together to share data.

The FISH 4432/4433 is particularly suited
to work with the TRACKER 5430 (4.3”
greyscale)/5380 (3.8” color) - Navman’s GPS
chartplotters with worldwide coverage.

There are t wo ways of connecting instruments
together; NavBus or NMEA.

NavBus

NavBus is a Navman proprietary system that
allows systems of multiple instruments to be
built using a single set of transducers. When
instruments are connected by NavBus:

• If the units, alarms or calibration are

changed in one instrument, then the values
will automatically change in all instruments
of the same t ype.

• Each instrument can be assigned to

a group of instruments. Then, if the
backlight setting is changed in one group,

Removing the display unit

The display unit can be removed after each
use for protection against the environment or
security reasons.

When removing the display unit, ensure that
the plugs left in the boat are not exposed to
the elements. Push the at tached dust covers
over the exposed ends of the plugs. Keep the
display unit in a dry clean place such as an
optional Navman carry bag.

it will automatically change for the other
instruments in that group. However, the
backlight setting will not change for
instruments in dif ferent groups.

• If an alarm sounds, mute it by clearing the

alarm on any instrument which can display
that alarm.

NMEA

NMEA is an industry standard for marine
instrument connections. Data sent by one
instrument over an NMEA line can be read and
displayed by another instrument that accepts
NMEA 0183 Version 2. It is not as flexible as
NavBus as it requires dedicated connections
between instruments.

Please contact your Navman dealer for
information on Navman’s full range of NMEA
enabled instruments and connection options.

DEPTH 2100

REPEAT 3100

Depth Repeater

Repeater for depth, speed, water temperature and battery
voltage. Accepts NavBus or NMEA data inputs from other
instruments.

6-5 Cleaning and mainte nance

To avoid damage, clean the screen only with
a damp cloth and mild detergent when dirty
or covered in sea salt. Avoid abrasive cleaners,
petrol or other solvents.

Cover or remove a transom-mounted
transducer when repainting the hull. If painting
over a through hull transducer with antifouling
paint, use only one coat of paint. Remove the
previous coat of antifouling paint by sanding
it lightly.

To optimize performance, avo id walk ing on
or jamming cables and connectors. Keep the
transducer free of weed, paint and debris. Do
not use a high pressure water blast on a speed
sensor paddlewheel as it may damage the
bearings.

When not in use, the FISH 4432/4433 can be
removed from the installation bracket and
stored in the Navman carry bag, or left on the
installation bracket and securely covered with
the sun cover supplied.

Appendix C - Troubleshooting

This troubleshooting guide is written with
the assumption that the user has read and
understood the relevant sections in this
manual.

It is possible in many cases to solve difficulties
without having to send the display unit back to
the manufacturer for repair. Please follow this
troubleshooting section before contacting the
nearest Navman dealer.

There are no user ser viceable parts. Specialized
methods and testing equipment are required
to ensure that the display unit is reassembled
correctly and is waterproof. Users who service
the product themselves will void the warranty.

Repairs to the product may only be carried out
by a service centre approved by Navman. If the
product must be sent into a service centre for
repair, it is essential to send in the transducer(s)
at the same time.

More information can be found on our Website:
www.navman.com.

1. The fish finder won’t turn on:

a) The FISH 4 432/4433 is designed to operate

on a 12 volt battery system, where the
voltage may vary from 10 to 16 volts. If an
excessive voltage is supplied, the unit will
turn off/not star t.

b) Check that the power cable connector

at the back of the display unit is securely
plugged in and the collar is locked in place.

The collar must be secure for watertight
connection.

c) Measure the battery voltage while the

batter y is under load - turn on some
lights, radio or other electrical equipment
connected to the battery. If the voltage is
less than 10 volts:

- the batter y terminals or wiring on the
terminals may be corroded.

- the batter y may not be charging
correctly or may need replacing.

d) Inspect the power cable from end to end

for damage such as cuts, breaks, squashed
or trapped sections.

e) Ensure that the red wire is connected to the

positive battery terminal and the black wire
to the negative batter y terminal. If wired for
the Auto Power option, ensure the yellow
wire is connected to the ignition circuit.
Also check the boat’s main switch circuit
(see sec tion 6-5 Wiring options).

f) Check for corrosion on the power cable

connector and clean or replace if required.

g) Check fuses that are placed in line with the

power cable. A fuse can be blown despite
appearing to be good or the fuse may be
corroded. Test the fuse or replace it with a
fuse known to be good.

NAVMAN

FISH 4432/4433 Installation and Operation Manual35

2. The fish finder won’t turn off:

The fishf inder may have been wired for

Auto power. In this case, the fishfinder
cannot be turned of f while the ignition
power is on. (See Auto power wiring in
section 6-5 Wiring options.)

3. The fishfinder operates erratically:

a) Check that the transducer does not have

debris (e.g. weed, plastic bag) caught
around it.

b) The transducer may have been damaged

during launching, running aground or while
underway with debris etc. If the transducer
has been impacted, it may have been kicked
up on the bracket. If it is not physically
damaged, reset the transducer back to
its original position. (See the Tra nso m
Transducer Installation Guide.)

c) When the transducer is less that 2 ft. (0.6 m)

from the bottom, the depth readings may
become inconsistent and erratic.

d) Manual Gain may be set too low, which may

cause weak bottom echo or no fish signals. If
in Manual Gain, try increasing the Gain.

e) Ensure the back of the bottom surface of

the transducer is slightly lower than the
front and the front is as deep in the water as
possible in order to minimize the generation
of bubbles through cavitation. (See the
Transom Transducers Installat ion Guide.)

f) Check the transducer and power cable

connectors at the back of the display unit
are securely plugged in and the collars are
locked in place. The collars must b e secure
for watertight connec tion.

g) Inspect the power cable from end to end

for damage such as cuts, breaks, squashed
or trapped sections.

h) Ensure there is not another fishfinder

or depth sounder turned on, which may
interfere with this fishfinder.

i) Elec trical noise from the boat ’s engine

or an accessor y may be interfering with
the transducer(s) and /or the Navman
fishf inder. This may cause the f ishfinder
to automatically decrease the Gain unless
using Manual Gain.

The fishf inder thus eliminates weaker

signals such as fish or even the bot tom

FISH 4432/4433 Installation and Operation Manual 36

from the display. This may be checked
by switching off other instruments,
accessories (e.g. bilge pump) and the motor
until the of fending device is located. To
stop problems from electrical noise, try:

- re-routing the power and transducer
cable(s) away from the boat’s other
electrical wiring.

- routing the display unit ’s power cable
directly to the battery with an in-line
fuse.

4. Bottom is not displ ayed:

a) The fishfinder may have Manual Range

selected and the depth may be outside the
range value selec ted. Either change the
fishfinder to Auto Range or select another
depth range (see section 4 -5 Range).

b) The depth may be outside the fishfinder’s

range. While in Auto Range, the display unit
will display “--.-” to indicate that there is no
bottom detected. A display of the bottom
should reappear when in shallower water.

5. The bottom is disp layed too far up
the screen:

The fishf inder may have Manual Range

selected and the selected Range value is
too high for the depth. Either change the
fishfinder to Auto Range or select another
depth range (see section 4 -5 Range).

6. Bottom echo disappears or erratic
digital readi ng while the boat i s moving:

a) Ensure the back of the bottom sur face

of the transducer is slightly lower than
the front and the front is as deep in the
water as possible in order to minimise the
generation of bubbles through cavitation.
(See the Transom Transducers I nstallation
Guide, for more information.)

b) The transducer may be in turbulent water.

Air bubbles in the water disrupt the echoes
returned, interfering with the fishf inder’s
ability to find the bottom or other targets.
This often happens when the boat is
reversed. The transducer must be mounted
in a smooth flow of water in order for the
fishfinder to work at all boat speeds.

c) Electrical noise from the boat ’s motor can

interfere with the fishfinder. Try some
suppression spark plugs.

NAVMAN

7. If the fi shfinder beeps when t urned on
but nothing is displayed:

The fishf inder may be operating, but the

backlight settings may have been set
too low. See section 2 Basic Operation,
to adjust the f ishfinder backlight. Press
twice to restore default backlight settings.

8. The wrong language is displayed:

See section 3-1 Setup > System.

9. Fuel used or remaining seem inaccurate:

a) If the engine is run while the fishfinder is

powered off, the fishfinder does not record
the amount of fuel used during that engine
run. Consequently, the Fuel remaining
value will be higher than the actual amount
of fuel remaining in the tank.

To avoid this problem, use the Auto
Power Wiring option described in section
6-5 Wiring options. This ensures that
the fishfinder powers on automatically
whenever the boat’s ignition is switched on.

b) In rough seas, fuel may surge back and

forth through the fuel transducer, resulting
in incorrect readings. Try installing a
one-way valve between the fuel transducer
and the fuel tank.

c) The Set remaining fuel value must be

reset after every refuelling (see section 3-3
Setup > Fuel).

d) The fuel tank may not ref ill to the same

capacit y each time due to air pockets.
This is par ticularly noticable with
underfloor tanks.

e) Fuel transducers wear out over time and

should be replaced af ter every 5000 litres
of fuel.

10. Flow indic ates no fuel or low fuel:

a) Check that the number of engines is set to

1. See section 3-3 Setup > Fuel.

b) Check that the fuel cable connectors are

securely plugged in and the collar is locked
in place. The collar must be locked in place
to give a watertight connection.

c) A fuel transducer may be clogged. If so,

remove the transducer from the fuel line
and gently blow through it in the opposite
direction to the fuel flow.

A fuel filter between the fuel transducer

and the fuel tank must be installed as per
the fuel installation guide. Failure to do so
will void the warranty.

d) Inspect the fuel cable from end to end for

damage such as cuts, breaks, trapped or
squashed sections.

e) Check that the fuel filter is clean.

11. A twin engin e installation shows only
one flow rate:

a) Check that the number of engines is set to

2. See sec tion 3-3 Setup > Fuel.

12. Erratic Fuel Flow rea dings:

a) The fuel flow transducer may have been

mounted too close to the fuel pump or may
be subjec t to excessive vibration. Refer to
the installation instructions supplied with
the fuel transducer.

b) Check for leaks in the fuel line or in the fuel

pickup in the tank.

c) The Flow filter value is not suitable for

the engine. Check that the value is not set
to zero, then try increasing the value until
a steady flow rate is shown. See section 3-3
Setup > Fuel.

d) A higher fuel Flow filter setting be

used on EFI (fuel injec ted) engines. See
section 3-3 Setup > Fuel.

13. There is no rea ding for fuel economy:

a) The boat must be travelling through the

water to generate an Econom y reading.

b) Check that the paddlewheel on the

transducer is spinning freely and that the
two magnets in the paddlewheel are still
in place.

14. There is a doub le bottom trace
displayed:

a) The boat may be in an area that generates

shadows. See section 4-1 Interpreting the
display.

b) In shallow water, the echoes may bounce.

Reduce the gain setting (see section 4 -4
Gain) and/or reduce the sonar pulse power
(see sec tion 3-2 Setup > Sonar).

c) Decrease the Range.

15. No Sonar Display

Sonar is turned off. See Section 3-1
System > Setup.
