1 Introduction  
Congratulations on choosing a Navman  
fish-finder. For maximum benefit, please read this  
manual carefully before installation and use.  
Important  
It is vital to the performance of the fishfinder  
that the transducer is installed in the best  
location. Please follow the installation  
instructions very carefully.  
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 4432/4433 is a high quality, dual-  
frequency sonar fishfinder 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.  
help identify the depth contours marked on  
charts. The FISH 4432/4433 is particularly 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)  
IMPORTANT NOTE ON USE. While any  
fishfinder can be used as an aid to navigation,  
accuracy can be limited by many factors,  
including the location of the transducer. It is  
the user’s responsibility to ensure the Navman  
fishfinder is installed and used correctly.  
The dual frequency capability enables the  
FISH 4432/4433 to operate and display:  
•
•
•
At a high frequency of 200 kHz.  
At a low frequency of 83 kHz.  
With the optional fuel kit, the FISH 4433 also  
becomes a sophisticated and easy-to-use  
fuel computer.  
Both frequencies side-by-side on a split  
display.  
•
Both frequencies combined together into a  
single display.  
All of the Navman 4000 Series fishfinders use  
new proprietary SBN-II Technology for sonar  
processing to improve Signal enhancement,  
Bottom recognition and Noise rejection.  
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.  
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 fishfinders for true  
returns.  
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.  
Using SBN-II Technology, the Navman  
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.  
fishfinder 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.  
The Navman fishfinder can also assist with  
navigation by providing depth information to

1-2 How the FISH 4432/4433 works  
The FISH 4432/4433 has two parts:  
- the transducer attached to the hull  
- the display unit.  
line of pixels. The most recent echo appears  
on the extreme right of the display, with the  
older echoes being scrolled towards the left,  
eventually disappearing off the display.  
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.  
The scroll speed depends upon the water  
depth and scroll speed setting. See section 3-2  
Setup > Sonar and section 4-1 Interpreting the  
display, for more information.  
The appearance of echoes displayed are  
affected by:  
When the pulse meets an object, 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 bottom 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.

Calibrate  
See section 3-8 Setup > Calibrate, for  
information about calibrating the fuel  
transducer(s).  
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 0to 30seconds.  
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 injected or four-stroke engines  
may require a larger value.  
3-4 Setup > Logs  
The values can be changed independently of  
each other. These log values are saved when  
the unit is turned off.

Warning:  
Keel offset  
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.  
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.  
Enter a positive keel offset value when the  
transducer is located below the water surface  
but the total depth is required.  
Calibrating the fuel usage can improve the  
accuracy of fuel measurements.  
Enter a negative keel offset value when the  
depth below the deepest part of the boat is  
required (such as the keel, the rudder or the  
propeller) and the transducer is located closer  
to the water surface.  
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.  
Use the cursor keys to select Keel offset,  
then press to display the Keel offset box.  
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.  
Use the or cursor keys to adjust the value.

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 fish are detected  
and displayed.  
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.  
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 below the  
boat during a certain period of time.  
Strength of echoes  
The colors indicate differences in the strength  
of the echo. The strength varies with several  
factors, such as the:  
The history of the sonar signal displayed  
depends on the depth of the water and the  
scroll speed setting.  
•
•
•
Size of the fish, school of fish or other object.  
Depth of the fish 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.)  
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 between 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.  
•
•
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 hulls at speed produce air bubbles  
and turbulent water that bombard the transducer.  
The resulting ultrasonic noise may be picked up by  
the transducer and obscure the real echoes.  
The scroll speed can be set by the user to  
display either a longer history with less fish  
information or a shorter history with more fish  
details. See section 3-2 Setup > Sonar.  
If the boat is anchored, the echoes all come  
from the same area of bottom. This produces a  
flat bottom trace on the display.  
Soft bottoms  
such as mud,  
weed and  
sand show  
as narrow  
bands  
The screen shot shows a typical sonar display  
with the Fish symbols turned Off.  
Hard bottoms  
such as rock  
or coral  
show as wide

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.

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 fish 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 frequency reduces the  
shadow effect considerably.

4-3 Fish detection and display  
Where to find fish  
Fish symbols Off  
Underwater features like reefs, wrecks and  
rocky outcrops attract fish. Use the 83/200  
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.  
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  
When fishing with the FISH 4432/4433 with  
the Fish symbols Off, a weak fuzzy band  
may appear between the bottom trace and  
surface. This might indicate a thermocline - a  
rapid change in water temperature, such as the  
edge of a warm or cold current. The temperature  
difference can form a barrier which the fish may  
not swim through. In fresh water, fish often  
collect around a thermocline.  
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 fish arches  
easier to see.  
A fish arch occurs when a fish 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 start 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.  
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 - there will  
be times when  
the fishfinder  
will not be able  
to differentiate  
between large air  
There are many reasons why fish arches may  
not be seen. For example:  
•
Poor transducer installation (see Transom  
Transducers Installation 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.  
bubbles, rubbish  
containing air,  
fishing floats etc.  
and genuine fish.  
•
Range is important. It will be much easier  
to see fish arches when using zoom mode  
to concentrate on a particular section  
of water, rather than just displaying  
everything from the surface to the bottom.  
Zooming increases screen resolution and is  
necessary for good fish arches.

•
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 4432/4433.  
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.  
Note: The Gain mode automatically changes to  
Manual Gain if the gain or threshold settings are  
adjusted by the user.  
Fishing Mode  
Use this mode to show as much detail as  
possible.  
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:  
Manual Mode  
The gain can be adjusted by the user to  
compensate for water depth and clarity.  
1. Set the threshold to 0%.  
2. Adjust the gain until the threshold line is  
just to the right of the unwanted noise.  
High Gain settings may amplify the normal  
background noise until it appears as random  
pixels.

4-5 Range  
Range is the vertical depth displayed on the  
FISH 4432/4433.  
Zoom Range and Zoom Offset  
On the Sonar Zoom and Sonar Bottom displays,  
a vertical bar is shown on the far right of the  
display. This is the zoom bar. The zoom bar  
shows the zoom range; that is, the area that  
is magnified.  
The Navman fishfinder has two range modes,  
Auto Range and Manual Range:  
•
In Auto Range, the fishfinder 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.  
Use the or cursor keys to adjust the  
zoom range.  
Use the or cursor keys to adjust the  
zoom offset.  
•
In Manual Range, the fishfinder shows only  
a selected depth range. In areas of rapidly  
changing bottom 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.  
Changing 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 ft. (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  
to select Autoor Manual.  
3. Press ENT to confirm.  
Tip: To quickly enlarge from manual to auto-  
range hold down + or - key for 1.5 seconds.

Fish recognition  
The echo strengths shown on the A-scope  
can be useful in recognising the type 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.  
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 particular echo is  
seen at future times on the fishfinder, it is likely  
to be the same fish species.

determined by the’height’ of the echo shown  
on the screen.

Economyis the distance travelled per unit of  
fuel used. The Fishfinder calculates this using  
the fuel used and boat speed (water speed or  
GPS speed - which ever is selected as the speed  
source – see section 3-3 Setup > Fuel).  
The bigger this number, the better the fuel  
economy. Adjust the throttle and trim to  
achieve the best fuel economy.  
Note: when water speed is selected as the

6-3 Mounting and removing the display unit  
There are two mounting arrangements:  
Select a position where the display unit will be:  
•
Flush mounting requires a solid panel with  
access behind for wiring and mounting  
screws. After flush mounting, the FISH  
4432/4433 cannot be tilted or moved after  
installation to reduce any unwanted glare  
or reflections. Carefully select the best  
viewing position before installation. This  
would generally be in a shaded area.  
•
•
At least 4” (100 mm) away from the compass.  
At least 12” (300 mm) away from any radio  
transmitter.  
•
•
At least 4 ft. (1.2 m) away from any antenna.  
Easy to read by the helmsman and crew while  
underway.  
•
Protected from physical damage during  
rough sea passages.  
•
Bracket mounting requires a panel for  
mounting the bracket. Ensure that the  
panel is not likely to deform and is not  
subject to excessive vibration. The bracket  
can be tilted and rotated and the FISH  
4432/4433 can be removed after each use.  
•
•
Easy to access the 12VDCpower source.  
Convenient to route the transducer cables.

Flush Mounting  
1. Cut a hole in the bulkhead for the display  
unit using the flush mount template.  
Removing the display unit  
The display unit can be removed after each  
use for protection against the environment or  
security reasons.  
2. Drill four holes for the mounting studs  
using the flush mount template.  
When removing the display unit, ensure that  
the plugs left in the boat are not exposed to  
the elements. Push the attached 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.  
3. Screw the four studs into the brass inserts  
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 several instruments (4433 0nly)  
Several Navman instruments can be connected  
together to share data.  
it will automatically change for the other  
instruments in that group. However, the  
backlight setting will not change for  
instruments in different groups.  
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.  
•
If an alarm sounds, mute it by clearing the  
alarm on any instrument which can display  
that alarm.  
There are two ways of connecting instruments  
together; NavBus or NMEA.  
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.  
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 type.  
Please contact your Navman dealer for  
information on Navman’s full range of NMEA  
enabled instruments and connection options.  
•
Each instrument can be assigned to  
a group of instruments. Then, if the  
backlight setting is changed in one group,

6-5 Cleaning and maintenance  
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.  
To optimize performance, avoid walking 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.  
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.  
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 B - Dimensions  
Appendix C - Troubleshooting  
This troubleshooting guide is written with  
the assumption that the user has read and  
understood the relevant sections in this  
manual.  
The collar must be secure for watertight  
connection.  
c) Measure the battery voltage while the  
battery is under load - turn on some  
lights, radio or other electrical equipment  
connected to the battery. If the voltage is  
less than 10 volts:  
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.  
-
the battery terminals or wiring on the  
terminals may be corroded.  
There are no user serviceable 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.  
-
the battery 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.  
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.  
e) Ensure that the red wire is connected to the  
positive battery terminal and the black wire  
to the negative battery 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 section 6-5 Wiring options).  
More information can be found on our Website:  
www.navman.com.  
1. The fishfinder won’t turn on:  
f) Check for corrosion on the power cable  
connector and clean or replace if required.  
a) The FISH 4432/4433 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 start.  
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.  
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.

2. The fishfinder won’t turn off:  
from the display. This may be checked  
by switching off other instruments,  
accessories (e.g. bilge pump) and the motor  
until the offending device is located. To  
stop problems from electrical noise, try:  
The fishfinder may have been wired for  
Auto power. In this case, the fishfinder  
cannot be turned off while the ignition  
power is on. (See Auto power wiring in  
section 6-5 Wiring options.)  
-
re-routing the power and transducer  
cable(s) away from the boat’s other  
electrical wiring.  
3. The fishfinder operates erratically:  
a) Check that the transducer does not have  
debris (e.g. weed, plastic bag) caught  
around it.  
-
routing the display unit’s power cable  
directly to the battery with an in-line  
fuse.  
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 Transom  
Transducer Installation Guide.)  
4. Bottom is not displayed:  
a) The fishfinder may have Manual Range  
selected and the depth may be outside the  
range value selected. 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.  
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.  
5. The bottom is displayed too far up  
the screen:  
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 Installation Guide.)  
The fishfinder 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 reading while the boat is moving:  
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 be secure  
for watertight connection.  
a) 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 minimise the  
generation of bubbles through cavitation.  
(See the Transom Transducers Installation  
Guide, for more information.)  
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.  
b) The transducer may be in turbulent water.  
Air bubbles in the water disrupt the echoes  
returned, interfering with the fishfinder’s  
ability to find the bottom or other targets.  
This often happens when the boat is  
i) Electrical noise from the boat’s engine  
or an accessory may be interfering with  
the transducer(s) and/or the Navman  
fishfinder. This may cause the fishfinder  
to automatically decrease the Gain unless  
using Manual Gain.  
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.  
The fishfinder thus eliminates weaker  
signals such as fish or even the bottom

7. If the fishfinder beeps when turned on  
but nothing is displayed:  
and the fuel tank must be installed as per  
the fuel installation guide. Failure to do so  
will void the warranty.  
The fishfinder may be operating, but the  
backlight settings may have been set  
too low. See section 2 Basic Operation,  
to adjust the fishfinder backlight. Press  
twice to restore default backlight settings.  
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.  
8. The wrong language is displayed:  
See section 3-1 Setup > System.  
11. A twin engine installation shows only  
one flow rate:  
9. Fuel used or remaining seem inaccurate:  
a) Check that the number of engines is set to  
2. See section 3-3 Setup > Fuel.  
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.  
12. Erratic Fuel Flow readings:  
a) The fuel flow transducer may have been  
mounted too close to the fuel pump or may  
be subject to excessive vibration. Refer to  
the installation instructions supplied with  
the fuel transducer.  
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) Check for leaks in the fuel line or in the fuel  
pickup in the tank.  
c) The Flow filtervalue 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.  
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.  
d) A higher fuel Flow filtersetting be  
used on EFI (fuel injected) engines. See  
section 3-3 Setup > Fuel.  
c) The Set remainingfuel value must be  
reset after every refuelling (see section 3-3  
Setup > Fuel).  
13. There is no reading for fuel economy:  
d) The fuel tank may not refill to the same  
capacity each time due to air pockets.  
This is particularly noticable with  
underfloor tanks.  
a) The boat must be travelling through the  
water to generate an Economyreading.  
b) Check that the paddlewheel on the  
transducer is spinning freely and that the  
two magnets in the paddlewheel are still  
in place.  
e) Fuel transducers wear out over time and  
should be replaced after every 5000 litres  
of fuel.  
14. There is a double bottom trace  
displayed:  
10. Flow indicates no fuel or low fuel:  
a) Check that the number of engines is set to  
1. See section 3-3 Setup > Fuel.  
a) The boat may be in an area that generates  
shadows. See section 4-1 Interpreting the  
display.  
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.  
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 section 3-2 Setup > Sonar).  
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.  
c) Decrease the Range.  
15. No Sonar Display  
Sonar is turned off. See Section 3-1
