1 Introduction

Congratulations on choosing the NAVMAN FISH450 Tricolor fishfinder. For maximum benefit, please
read this manual carefully before installation and use. Special terms are explained in Appendix C.

The NAVMAN FISH450 Tricolor

The FISH450 Tricolor is an ultrasonic fishfinder with powerful software and a three colour display. As well
as detecting fish the unit measures water depth, boat speed, water temperature and battery voltage and
has two distance logs (trip and total with one displayed at a time). With an optional fuel kit the FISH450
Tricolor is also a sophisticated yet easy to use fuel computer.

How the NAVMAN FISH450 Tricolor finds fish and determines the depth

An installed FISH450 Tricolor has two parts:

- a transducer attached to the hull

- the display unit.
The transducer generates an ultrasonic (sound) pulse, which travels down
towards the bottom. When the sound pulse meets an object, such as a
fish or the bottom, some of the pulse is reflected back up towards the boat
and is received by the transducer. The depth of an object can be calculated
by measuring the time between sending the pulse and receiving its echo.

The display unit analyses the reflections from each pulse, removes
unwanted reflections (from bubbles and other noise) and displays what is
in the water under the boat. The display shows three colours: Blue for the
strongest reflections, Red for medium and Green for the weakest reflections
(see section 3 - 2). These colours help users better interpret what is in the water.

There are several reasons the returned echo strength can vary. Larger fish usually return stronger echos, as
do fish in the centre of the beam where the pulse is stronger. Reasons for weak echos include the fish or
object being in deep water or turbid water, or in the edge of the beam where the pulse is weaker.

The unit will detect the bottom down to 1000 feet (300 metres), depending on the clarity of the water and
measures depths to an accuracy of 2%.

Assisting with navigation

The FISH450 Tricolor can be used to find fish, to locate features on the bottom such as reefs or wrecks
and to help recognise favourite fishing spots from the profile of the bottom. Use the FISH450 Tricolor to
assist navigation by following the depth contours marked on charts.

IMPORTANT NOTE ON USE - While the FISH450 Tricolor can be used as an aid to navigation, its
accuracy can be influenced by many factors, including the location of the transducer. It is the user’s
responsibility to ensure the unit is installed and used correctly.

How to find fish

Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the FISH450 Tricolor to find
these features, then look for fish by passing over the feature slowly several times using the Zoom screen
(See section 3-1). Where there is a current, the fish will often be found downstream of the feature.

For deep sea fishing, a rapid change in temperature may indicate the edge of a warm or cold current. The temperature
difference may form a barrier which fish tend not to swim through. Search for fish either side of the barrier.

Cleaning and maintenance

The FISH450 Tricolor should be cleaned with a damp cloth or mild detergent. Avoid abrasive cleaners
and petrol or other solvents.

Always cover or remove the stern mounted Aquaducer when repainting the hull. If painting over a through
hull transducer with antifouling then use only one coat of paint. When repainting the transducer remove
previous coats by lightly sanding.

Temperature warning

Do not expose the unit to temperatures exceeding 50°C (122°F) or the LCD may not be useable until it cools down.

Never leave the unit exposed to high temperatures even for a few minutes. (e.g. on the dashboard of a car).

3-2 Fish History and Zoom Screens

Fish History screen

The Fish History screen displays the most recent
signals on the right of the screen, and the oldest
signals on the left. Vertically, this screen always

Fish detection

The FISH450 Tricolor analyses all received echos
and recognises the characteristic patterns returned
by fish. These echos are displayed on the screen
as a fish symbol. The default setting is for an
associated depth to be shown with fish symbols.

Advanced users sometimes prefer to turn off the
fish symbol feature and interpret the echo patterns
themselves. The following is an example with fish
symbols turned off:

Zoom screen

The Zoom screen is used to view greater detail in
an area of interest (e.g. fish close to the bottom).
The right portion is the Full Range Section and
the left is the Zoom Section.

The Zoom Bar, located on the very right of the
screen, determines the depth range of the Zoom
Section and the amount of magnification:

The Full Range Section illustrated is 0 to 30 m and
the Zoom Bar is between 14 and 29m. Therefore
the area between 14 and
29m is enlarged in the
Zoom Section.

To set the depth of the

Zoom Section, move the
Zoom Bar up or down by

pressing the Cursor Up
or Down key. To make
the Zoom Bar smaller (to
increase magnification),
press the Cursor Left
key. To make the Zoom
Bar bigger (to decrease
magnification), press the
Cursor Right key.

The Zoom Bar can be adjusted in the Fish History
screen before switching to the Zoom screen.

Strength of returned echos

The three colours indicate differences in the
strength of the returned echo: blue is the strongest,
red is medium strength and green is the weakest.

There are several reasons why the strength of the
returned echo varies:

• The size of the fish, school of fish or other

• The depth of the fish or object.

• The location of the fish or object. The area

• The clarity of water. Particles or air in the

turbulent water that bombard the transducer. The
resulting ultrasonic noise may be picked up by the
transducer and obscure the real echos.

When the fish symbol feature is
enabled, any echo returned that
fits the profile of a fish is
displayed on the screen with a
fish symbol. To interpret and use
this function, see Setup - Display
section 4-6.

When a boat is stationary, all bottom echos will come from the same small area of
bottom. This will produce a flat bottom trace on the screen as shown on the right.

The appearance of the Fish History and Zoom screens can be

changed to suit individual preferences. This screen has the

depth reading in larger text as a result of the temperature

reading being disabled (see Setup - Display section 4-6).

Shadows

Shadows are areas where the ultrasonic beam cannot ‘see’. These
include hollows on the bottom or beside rocks and ledges where the
strong echo returned off the rock obscures the weaker echo of the fish.

When looking for small objects including fish, users should consider that
there are places where fishfinders cannot ‘see’.

Shadow - where objects are hidden in the bottom echo.

These fish will be hidden in the bottom echo.

Range

Range is the depth of water displayed vertically.
The FISH450 Tricolor has two range modes, Auto
Range and Manual Range:

• In Auto Range, the unit adjusts the depth

range so that the bottom is shown in the
lower part of the screen. The use of Auto
Range is recommended.

• In Manual Range, the range can be set by

pressing the Increase Range or Decrease

Range key.
To switch between Auto Range and Manual Range
hold the Increase Range or Decrease Range key
down until the dialogue box “Auto Range” or
“Manual Range” briefly appears.

Manual Range is useful to prevent the screen
redrawing when there are rapid changes in depth.
(E.g. looking at the sea floor surrounding a pinnacle.)

Gain

Gain controls the amount of detail displayed on
the screen. The FISH450 Tricolor has two gain
modes, Auto Gain and Manual Gain.

• In Auto Gain, the gain is automatically

adjusted. The use of Auto Gain is

recommended.

• Manual Gain can be set between 1 and 9, low

values may not show enough detail, while too

high a setting may clutter the screen. When in

Manual Gain the gain symbol

Bottom Lock

Bottom Lock fixes the Zoom Bar to the bottom, so
the bottom is always displayed in the Zoom
Section, regardless of changes in depth.

To turn Bottom Lock on, move the Zoom Bar down
until it touches the bottom and the dialogue box
“Bottom Lock On” briefly appears. To turn Bottom
Lock off press the Cursor Up key.

Should the bottom rise to meet the Zoom Bar when
bottom lock is off, the Zoom Bar will temporarily track
the bottom. This condition will cease when the depth
exceeds the original depth of the Zoom Bar.

3-3 Sonar screen

The Sonar screen displays the depth and strength
of the echos returned from each ultrasonic pulse.

This raw signal is enhanced by the Colouration
and Gain settings and then displayed on the Fish
History or Zoom screen as a single vertical row of
dots.

The key to interpreting the Sonar screen is to look
at the strength (stronger echos project further to
the left) and the depth (distance down the screen)
of the echos.

• Increase the blue part of the colouration bar
by pressing the Cursor Right key if there are
too few blue (strong) echos being displayed.

• Decrease the blue part of the colouration bar
by pressing the Cursor Left key if there are

Remaining is the amount of fuel remaining in the
fuel tank(s) displayed in litres or gallons.

Flow (fuel consumption) is shown in litres or
gallons per hour. For twin engine installations, the
fuel flow for each engine is shown separately. This
is useful for checking that both engines are under
the same load.

Economy is the distance travelled per unit of fuel
used. The FISH450 Tricolor uses boat speed and
fuel consumption for this calculation. The Economy
units are set by the units selected for speed and
fuel (e.g. NM/L, NM/G, MI/L, MPG, KM/L, KM/G).
Adjust the throttle and trim for the best Economy.
The bigger the number the better the economy.

the water temperature at that point. An alarm for a
specific temperature or rate of change of temperature
may be enabled in Setup - Alarms section 4-1.

Battery

The battery voltage is displayed numerically.
Monitoring this helps prevent the battery running
flat without warning, particularly when using
electronic devices while the battery is not charging.
The battery voltage may provide an early warning
of battery or alternator failure. The battery voltage
will increase after the motor has started if the
alternator is charging correctly.

Log

One of two distance logs can be displayed: Trip
Log or Total Log. Both logs are stored in NAVMAN's
NVM (non volatile memory) when the unit is
switched off. To change the which log displayed see
section 4-6. The Trip log must be reset manually as
most users will want to start and stop during a trip.

Speed is the current speed of the boat.
Depth is the current depth of the bottom.

time the fuel tank is refilled or the low fuel alarm
will be meaningless! When partially filling the fuel
tank use Set Remaining.

Tank Size

Enters the capacity of the fuel tank into the unit for
use with the Tank Full option. It is best to measure
the fuel tank size by draining, then filling with fuel
in the usual manner and using the fuel dispenser’s
meter to measure the amount. Be aware of air
pockets, particularly in underfloor tanks.

Set Remaining

Changes the fuel remaining value. Use this feature
when not filling the fuel tank to capacity, or when
syphoning fuel out.

Clear Used

Resets the fuel used (Used) value to 0.0. Use this
to start re-measuring the amount of fuel used.

Units

Sets the units of fuel to L (Litres), USGAL (US
Gallons) or IMPGAL (Imperial Gallons)

Num Engines

Sets the number of engines to 1, 2 or 0. If 0 is
selected the fuel features are turned off and Fuel

Fuel Cal

Calibrating the fuel usage can increase the
accuracy of fuel measurements from +/- 10% to
better than +/- 2%. For twin engine installations
calibration of each transducer is required.

Calibrating the fuel transducer requires accurate
measurement of the fuel used (Used). This is easiest
with a small portable tank. It should be noted that
due to air pockets, it is very difficult to fill underfloor
tanks to the same level twice. At least 15 litres should
be used to ensure an accurate calibration. (The
more fuel used, the more accurate the calibration
will be.) Each transducer in a twin engine installation
must be calibrated separately. This may be done at
the same time with two portable tanks, or at different
times using one tank at a time.

The procedure is as follows:

1) Reset the fuel used amount on the FISH450
Tricolor to 0.0 by selecting Clear Used in the
Setup - Fuel menu, then selecting Yes .

2) Connect the measurement tank(s) to the
engine(s) via the fuel transducer(s).

3) Run the engine(s) at normal cruising speed
until at least 15 litres is indicated (30 for twin
engines).

4) Check the actual amount of fuel used per
engine. The easiest way to do this is to refill
the tank(s) to the original level(s) and record
the value(s) shown on the fuel dispenser.

5) Select Fuel Cal on the fuel menu. The amount
of fuel that the FISH450 Tricolor has recorded
will be displayed. Use the Cursor Left or Right
key to change this to the actual fuel amount
used. Press the Menu key when the value is
set. (Repeat for the other engine in a twin
engine installation).

Flow Filter

Sets the period over which the fuel flow is
averaged. Averaging can be set from 1 to 255
seconds.

Normally engines do not draw fuel from the tank
at a steady rate. They draw fuel at a high rate for a
few seconds until the carburettor bowl or fuel
injection reservoir is full, then draw no fuel for a
few seconds. If the true flow rate were displayed,
it would be too erratic to read.

Usually a value of 10-15 seconds will give a
satisfactory result for carburettor engines. Fuel
injected engines may require a larger value.

This setting affects the flow rate (Flow) and
Economy displays. It does not affect the fuel used
(Used) measurement.

known distance, or from another instrument (e.g.
GPS, DGPS or calibrated speedometer). The
calibrated instrument may be on board or on
another boat travelling alongside.

Notes for accurate calibration:

• GPS speeds are only accurate enough when
above 20 knots, DGPS when above 5 knots. Best
results are achieved in calm conditions where
there is minimal current (best at high or low tide).

• Paddlewheel devices are generally accurate
enough when between 6 and 20 knots.

5 Installation

Correct installation is critical to the performance of the unit. There are two components to install, the
FISH450 Tricolor and the transducer. The transducer which comes standard with the FISH450 Tricolor is
called an Aquaducer and includes three elements: speed, temperature and ultrasonic sounder.

It is vital to read the entire installation section of this manual and the documentation that comes with your
transducers before attempting installation.

5-3 Mounting the Aquaducer

The location and angle of the Aquaducer are the
most critical parts of the installation. If the location
and angle are not correct, the Aquaducer can’t
perform at its designed potential.

Transom mount Aquaducer

IMPORTANT - the Aquaducer cable cannot be cut
or shortened.

The Aquaducer can be installed on any outboard or
stern-drive powered boat. Inboard powered boats must
be fitted with a through-hull transducer as the propeller
wash interferes with the operation of transom mounted
transducers. The transom mount Aquaducer has a
safety “kick up” mounting bracket which will normally
prevent damage to the Aquaducer should it impact
the bottom or floating debris in the water.

Final position of Aquaducer:

Position Aquaducer
as low as possible

5°

Location

Select a position for the Aquaducer that will:

• allow the Aquaducer a smooth flow of water
over its surface at all times.

• ensure a mount as deep in the water as
possible.

• be clear of any interference from the trailer
when launching or retrieving the boat.

• be away from planing strakes or other
projections from the hull that may cause
aerated water to flow over the face of the
transducer.

• be away from the propeller.

• be at least 150 mm (6") away from the keel
of the boat.

• IMPORTANT - place the Aquaducer against

the transom and check that the bottom
surface is angled approximately 5° forward
in order to minimise the generation of
bubbles through cavitation. If necessary, use
one or more of the three wedges provided
(one 4° and two 8°) to achieve this angle.

• Position the bracket and selected wedge(s)
as low as possible without any part
protruding below the hull. Mark the screw
hole centres on the transom through the
centre of the bracket slots. Mark them so that
when the screws are tightened the screw
heads sit flat on the surface of the bracket.

• Drill the two screw holes using a 3 mm drill
bit. Make sure the holes are angled so that
when the screws are tightened the screw
heads sit flat on the surface of the bracket.

• Insert the Aquaducer into the
bracket. Use the stainless screws
provided to attach the bracket and
wedge(s) to the transom. Ensure
again that the top of the bracket
is horizontal and that the
bracket is as low as
possible without
protruding below the
hull. Fill holes with a
sealing compound before
inserting screws. Tighten the two screws.

• Drill a hole and insert the third screw in the
middle of the bracket.

• Finally push the Aquaducer down so it
‘clicks’ into place.

• Once in place test the Aquaducer is
connected by turning the unit on. If the
Aquaducer is not connected then the
message “No transducer detected. Enter
simulation mode? Yes/No” will appear. (see
Simulate Mode section 4-10). Please see the
section on Troubleshooting Appendix B.

19

5-4 Other depth and speed / temperature transducers

Correct transducer installation is critical to the
performance of the unit. Most transducers come
with instruction. It is important to carefully read and
follow the instructions provided.

NAVMAN through-hull transducers and speed/

temperature transducers are available for the
FISH450 Tricolor. These are separate transducers
which require separate mounting.

Please consult your NAVMAN dealer when
attempting to install other transducers.

5-5 Fuel transducers

Fuel transducers

A single or twin engine fuel kit can be purchased
separately. It is supplied with the “NAVMAN Fuel
flow transducer installation instructions”. This
transducer is for use with petrol engines only.

A fuel filter must be placed on the fuel line between

the transducer and the fuel tank.
When the installation is complete, please follow the

instructions in Setup Fuel section 4-2.
Note: Before the fuel features can be used they

must be enabled by setting Num Engines to either
1 or 2.

5-6 Mounting the FISH450 Tricolor display unit

Mounting the bracket

1. Select a position where the display head will
be:

• At least 300mm away from the compass.

• At least 300mm away from any radio
transmitter.

• At least 1.2 metres away from the VHF
antenna.

• Easy to read by the helmsman and crew
while underway. Colours are best when
viewed from directly in front of the unit.

• Protected from physical damage during
rough sea passages.

• Easy to access the 12 volt power source.

• Convenient to route the transducer cables.

2. Remove the round base from the centre of the

bracket.

3. Affix the round base using the 4 stainless screws

provided.

4. Orientate the bracket on the round base and

screw down the central locking knob.
Note: There is also a flush mount kit available.

Please consult your NAVMAN dealer.

Mounting the FISH450 Tricolor

1. Attach cables.

2. Slide mounting screws into the slots on the
mounting bracket. The rubber washers go between
the body of the fishfinder and the mounting bracket.

Removing the FISH450 Tricolor

You may remove your fishfinder after each use for
protection against the environment or security
reasons.

If you do remove the FISH450 Tricolor, ensure that
the plugs left in the boat are not exposed to the
elements. Keep the unit in a dry clean place.

FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

5-7 Wiring connection

The FISH450 Tricolor uses a
colour coded connector
system:

Black connector = Power
Blue connector = Aquaducer
White connector = Fuel
The connectors are bayonet
type, push the plugs into the
sockets then turn the collars to
lock. Make sure the collars are
secure for water tight connection.

Important

• The connection to the
battery must be made via a
fuse (1 amp) or circuit
breaker.

• If possible, route the
transducer cables away
from other wiring on the
boat. Electrical noise from
engine wiring, bilge pumps,
and other equipment can
affect the unit.

• Connect the red wire of the
two-core power cable to
the positive supply and the
black wire to the electrical
ground.

• The shortest and most
direct connection to the
boat’s battery helps to
minimise voltage drop.

• If the Auto Power option is
not used, connect the
yellow Auto Power wire to
the black ground wire.

External beeper

A 12 volt external beeper with a built in
drive circuit may be connected. The
maximum current draw is 250mA.

Warning: The FISH450 Tricolor must be run off a 12 volt battery
and must not be run off a circuit without a battery.

Appendix B - 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 unit back to the
manufacturer for repair. Please follow this
troubleshooting section before contacting the
nearest NAVMAN dealer.

There are no user serviceable parts. Specialised
methods and testing equipment is required to
ensure that the unit is reassembled correctly and
is waterproof. Users who service the FISH450

Tricolor themselves will void the warranty (see
appendix D.

Repairs to the FISH450 Tricolor may only be
carried out by a service centre approved by Talon
Technology. If it is found that the unit 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 fishfinder won’t turn on:

a) The FISH450 Tricolor is designed to operate

on 12 volt battery systems, where the voltage
may vary from 10 to 16.5 volts. If an excessive
voltage is supplied to the unit, a resettable fuse
will be tripped, turning the unit off.

b) Check the power cable connector at the back

of the unit is securely plugged in and the collar
is locked in place. The collar must be secure
for water tight connection.

c) Measure the battery voltage. If the voltage is

less than 10 volts:

- the battery terminals or wiring on the
terminals may be corroded.

- 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 or squashed
sections.

e) Make certain the power cable’s red wire connects

to the positive battery terminal and the black wire
to the negative battery terminal or ground. (If
wired for Auto Power, then ensure the red and
yellow wires are connected to the boat’s power
switch. Also check the boat’s power switch circuit.
See Auto Power section 5-8.)

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. Test the fuse or replace

FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

it with a fuse known to be good.

2. The fishfinder operates erratically:

a) Check the Aquaducer does not have debris (eg

weed, plastic bag etc.) caught around it.

b) The Aquaducer may have been damaged during

launching, running aground or while underway
with debris etc. If the Aquaducer has been
impacted, it may have been kicked up on the
bracket. If it has not been physically damaged,
push it back down so it ‘clicks’ into place.

c) When in water less than 2 feet (0.6m) the bottom

and depth readings may become inconsistent and
erratic. This depth is measured from the transducer
and does not allow for any Keel Offset setting.

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

weak bottom echo, or no fish signals. If you have
the Auto Gain disabled try increasing the gain.

e) Ensure the bottom surface of the Aquaducer is

angled approximately 5° forward and as low as
possible in order to minimise the generation of
bubbles through cavitation. See Mounting the
Aquaducer section 5-3.

f) Check the transducer and power cable

connectors at the back of the unit are securely
plugged in and the collar is locked in place. The
collar must be secure for water tight connection.

g) Inspect the transducer and power cables from

end to end for damage such as cuts, breaks or
squashed sections.

h) Ensure there is not another fishfinder or depth

sounder turned on, which may interfere with the
FISH450 Tricolor.

i) Electrical noise from the boat’s engine or an

accessory may be interfering with the transducer(s)
and/or the FISH450 Tricolor. This may cause the
unit to automatically decrease the gain unless using
Manual Gain. The unit thus eliminates weaker
signals such as fish or even the bottom from the
display. This may be checked by switching off other
instruments, accessories (e.g. fridges) and the
motor until the offending device is located. To stop
problems from electrical noise, try:

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

- routing the unit’s power cable directly to the
battery instead of through a fuse block or
ignition switch.

3. Bottom is not displayed:

a) If in Manual Range and the depth reading is

displayed, check that the depth is not greater
than the range selected. (see section 3-2)

b) The depth may be outside the fishfinder’s range.

23

While in Auto Range, the unit will flash the last
depth displayed, then display “--.-” to indicate
that there is no bottom detected. A display of
the bottom should reappear when it is shallower
than 300m (1000 ft).

4. Bottom echo disappears or erratic digital
reading while your boat is moving:

a) Ensure the bottom surface of the Aquaducer is

angled approximately 5° forward and as low as
possible in order to minimise the generation of
bubbles through cavitation. See Mounting the
Aquaducer section 5-3.

b) The transducer may be in turbulent water. Air

bubbles in the water disrupt the echos returned,
interfering with the FISH450 Tricolor’s ability to
find the bottom or other targets. This often
happens when you reverse the boat. The
transducer must be mounted in a smooth flow of
water in order for the unit to work at all boat speeds.

c) Electrical noise from the boat’s motor can

interfere with the FISH450 Tricolor. Try some
suppression spark plugs.

5. Fuel Used and/or Remaining amount(s)
seem incorrect:

a) Running the engine without the FISH450 Tricolor

turned on will result in the fuel used (Used) not
being recorded. This means that the fuel remaining
(Remaining) value will read higher than what is
actually in the tank. Installing the unit in the Auto
Power configuration will solve this problem, as the
unit is powered on and off automatically when the
vessel’s power is switched on and off.

b) Incorrect readings may be caused by fuel surging

back and forward through the transducer in rough
seas. Try installing a one way valve between the
fuel transducer(s) and the fuel tank.

c) Fuel Remaining must be set to the amount of

fuel on board after every refuelling.

d) Air pockets when filling the tank may have

caused the tank to not fill completely.

e) Calibrate the fuel transducer after 100 litres have

been run through - so the turbine shaft beds
into the bearings correctly.

f) Fuel transducers wear out over time and should

be replaced every 5000 litres of fuel.

g) Also check all other fuel problems listed in the

troubleshooting guide.

6. No/low fuel flow (Flow) indicated:

a) Check the fuel cable connectors are securely

plugged in and the collar is locked in place. The
collar must be secure for water tight connection.

b) The fuel transducer(s) must be installed after a

fuel filter or they may clog. To clear a clogged
fuel transducer(s) remove the transducer(s) from
the line and gently blow through the tranducer(s)

24

NAVMAN

in the opposite direction to the fuel flow.

c) Inspect the fuel cable(s) from end to end for

damage such as cuts, breaks or squashed

sections.
d) Check that the fuel filter(s) in the line are clean.
e) Ensure that the fuel flow transducer(s) has not

been exposed to excessive heat or vibration.

7. Only one flow rate value shown for a twin

engine installation:

a) In the Setup Fuel menu Num Engines must be

set to 2.

8. Erratic fuel flow readings:

a) The mounting position of the fuel flow transducer

must not be too close to the fuel pump(s) and

not subject to excess vibration.
b) Check for air leaks in the fuel hose(s) or fuel

pick-up(s) in the tank(s).
c) The filtering level (averaging) has not been set

to suit the engine(s). In the Setup Fuel menu,

increase the Flow Filter value until a steady flow

rate is indicated. Check the fuel flow (Flow)

readings are not zero.

9. No fuel economy reading:

a) For the FISH450 Tricolor to be able to calculate

an economy reading, the boat must be

displaying a speed greater than zero.
b) Check the paddlewheel on the Aquaducer is

spinning freely. Check that the two magnets in

the paddlewheel are in place.

10. Over temperature warning message

displayed:

a) Error message. “Warning: Temperature exceeding

70°C. Reduce temperature to improve colour

clarity.” Press the Alarm key to acknowledge

message and reduce the temperature of the unit.

11. If the unit beeps when turned on but

nothing is displayed:

a) The unit may be operating, but the display’s

calibration settings (Red Cal, Blue Cal, Display

Cal. See section 4-6) may have been set too high

or low. Reset the display defaults so the unit

displays normally. While the unit is off, hold the

Cursor Right key and while holding it, hold the

Power On key. See section 4-9 for default values.

12. The unit is setup in such a way that the

user is not sure what to adjust to get it

operating normally:

a) The units factory defaults can be restored to

reset the unit a known configuration. See

Resetting to factory defaults section 4-9.

13. The wrong language is displayed:

a) See Getting Started section 2 on how to change

the language without using the menu system.
b) See Setup Language section 4-8.

SONDEUR DE PECHE FISH450 Tricolor Notice d'installation et d'utilisation

NAVMAN

1 Introduction

Nous vous remercions d’avoir choisi ce sondeur de pêche FISH450 Tricolor NAVMAN. Pour un
fonctionnement optimal, nous vous recommandons de lire attentivement ce mode d’emploi avant d’installer
et d’utiliser votre sondeur. En appendice C, un lexique définit les termes spécifiques.

Le FISH450 Tricolor NAVMAN

Le FISH450 Tricolor est un sondeur à ultrasons composé d’un logiciel performant et d’un écran 3 couleurs.
Ce sondeur détecte les poissons et mesure la profondeur et la température de l’eau, la vitesse du bateau
et la tension électrique à l’entrée de l’appareil. Il possède un loch journalier et un loch totalisateur (affichage
d'une seule information à la fois). Connecté à un kit essence optionnel, le sondeur FISH450 Tricolor
devient alors une véritable centrale qui vous permet de gérer votre consommation d’essence.

Comment le sondeur FISH450 Tricolor NAVMAN détecte les
poissons et détermine la profondeur.

Le FISH450 Tricolor se compose :

- d’un capteur monté sur la coque - d’un appareil.
Le capteur émet un écho ultrason qui est envoyé vers le fond. Lorsque l’écho rencontre une
cible, tel qu’un poisson ou le fond, une partie de cet écho est renvoyée vers le bateau et est
reçue par le capteur. La profondeur de la cible est calculée en mesurant le temps écoulé entre l’envoi de l’écho
et sa réception par le capteur.

L’appareil analyse l’écho retourné, supprime tous les échos indésirables (bulles et autres parasites) et
affiche ce qui se trouve sous le bateau. Le sondeur utilise 3 couleurs d’affichage, le bleu pour les échos
les plus intenses, le rouge pour les échos moyens, le vert pour les échos de faible intensité (section 3-2).
Ces couleurs facilitent l’interprétation des informations affichées.

Plusieurs raisons peuvent expliquer la différence d’intensité des échos retournés. En général, plus le poisson est
gros, plus l’écho retourné est important. De plus, l’écho retourné par un poisson situé au centre du cône d’émission,
où l’écho émis est plus intense, retournera un écho plus intense. Un poisson situé en eaux profondes, dans des
turbulences ou sur les bords du cône d’émission, où l’écho émis est plus faible, retournera un écho plus faible.

Le sondeur peut détecter un fond jusqu’à 1000 pieds (300 mètres) selon la limpidité de l’eau, le type de
capteur, et mesurer la profondeur avec une précision jusqu’à 2%.

Aide à la navigation

Le FISH450 Tricolor permet de détecter des poissons, de localiser des cibles sur le fond comme des récifs ou
des épaves et de retrouver vos coins de pêche favoris grâce au profil du fond. En suivant les courbes de
profondeur de votre carte papier, vous pouvez utiliser le sondeur FISH450 Tricolor comme une aide à la navigation.

REMARQUE IMPORTANTE CONCERNANT L’UTILISATION DE VOTRE SONDEUR : si vous utilisez votre
sondeur de pêche FISH450 Tricolor comme une aide à la navigation, notez que sa précision dépend entre
autres de l’emplacement du capteur. L’utilisateur doit s’assurer que le capteur est monté et utilisé correctement.

Comment détecter des poissons

Les récifs, les épaves ou les rochers attirent les poissons. Avec le FISH450 Tricolor, repérez ce type de fond puis
recherchez des poissons sur l’écran zoom en passant doucement plusieurs fois au-dessus de cet emplacement
(section 3-1). S’il y a du courant, les poissons se trouvent généralement en aval de cet emplacement. Si vous
recherchez des poissons d’eaux profondes, un changement rapide de la température de l’eau peut indiquer que
vous vous trouvez au bord d’un courant chaud ou froid. La différence de température peut alors former une
barrière que le poisson ne franchira pas. Recherchez les poissons de l’autre côté de cette barrière.

Nettoyage et entretien

Vous pouvez nettoyer votre sondeur FISH450 Tricolor avec un chiffon humide ou imprégné de détergent doux.
N’utilisez pas d’abrasifs, d’essence ou autres solvants. Lorsque vous peignez la coque protégez ou ôtez toujours
l’Aquaducer monté à l’arrière. Si vous appliquez de l’antifouling sur un capteur passe-coque ne passez qu’une
seule couche. Si vous devez appliquer une autre couche ôtez les couches précédentes en sablant légèrement.

Remarque sur la température d’utilisation

Ne pas exposer l’appareil à une température de plus de 50°C (122°F) dans quel cas l’écran ne serait plus
opérationnel jusqu’à ce que la température baisse. Ne jamais exposer l’appareil à de hautes températures
même pendant quelques minutes (ex. sur le tableau de bord d’une voiture).
