1 Introduction
This manual also explains how to operate the
FISH 4500/4600 effectively and provides trou-
bleshooting information and performance tips.
Congratulations on choosing a Navman fish-
finder. For maximum benefit, please read this
manual carefully before installation and use.
Important
This manual describes how to install and set up
the FISH 4500/4600 and the associated dual-
frequency transom transducer. (If a through
hull transducer is used, refer to the Installation
Instructions supplied with that transducer.)
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.
1-1 Benefits of the FISH 4500/4600
The FISH 4500/4600 is a high quality, dual-
frequency sonar fishfinder that is supplied with
a dual-frequency transducer. It uses TFT (Thin
Film Transistor) technology to provide a color
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 colors on the sonar displays are customiz-
able, with a choice of four 16 color palettes and
one 8 color palette. The colors represent differ-
ent signal strengths, making the sonar displays
easy to interpret.
The Navman fishfinder can also assist with
navigation by providing depth information to help
identify the depth contours marked on charts.
The FISH 4500/4600 is particularly suited to
work with the TRACKER 5500/5600 - Navman’s
color display GPS chartplotter with worldwide
coverage.
The two instruments can be connected together
using either NavBus or NMEA, so they can
share data.
IMPORTANT NOTE ON USE. While any
fishfinder can be used as an aid to navigation,
accuracy can be limited by many factors, includ-
ing 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 4500/4600
also becomes a sophisticated and easy-to-use
fuel computer.
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.
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.
Using SBN-II Technology, the Navman 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 dual frequency capability enables the
FISH 4500/4600 to operate and display:
•
•
•
At a high frequency of 200 kHz.
At a low frequency of 50 kHz.
Both frequencies side-by-side on a split dis-
play.
Both frequencies combined together into a
single display.
•
This capability, combined with a variable power
output of up to 600 W RMS, ensures that the
FISH 4500/4600 operates effectively in shallow
and deep water.
The FISH 4500/4600 can detect the bottom to a
depth of 2000 feet (600 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.

1-2 How the FISH 4500/4600 works
The FISH 4500/4600 has two parts:
- 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 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 4500/4600 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 4500/4600 converts each echo into
an electronic signal, displayed as a vertical 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 disap-
pearing off the display.
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 af-
fected by:
•
•
•
the fishfinder settings (frequency selected,
range and gain settings)
echoes (different fish types, different bot-
tom types, wrecks and seaweed)
noise (water clarity and bubbles).
See section 4-1 Interpreting the display, for more
information.

Set remaining
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.
Before doing a partial refill of the tank or remov-
ing fuel manually from the tank (for example, by
siphoning it off):
1. Note the Remainingreading 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 remainingand update
the reading.
It is essential to do this whenever some fuel
is added or removed. Otherwise, the read-
ing on the Fuel display (see section 5-6 Fuel
Display) and the Low Fuel Alarm (see section
3-5 Setup > Alarms) are meaningless.
For twin engine installations, the fuel flow for each
engine must be adjusted separately.
TheFlowfiltercanbesetfrom0to30seconds. Use
thelowestvaluewhichgivesastableflow. Usuallya
valueof5to10secondswillgiveasatisfactoryresult
for two-stroke carburettor engines. Fuel injected or

Obtain an accurate measurement of the boat’s
speed from a GPS receiver; or by following another
boat travelling at a known speed; or by making a
timed run over a known distance.
Note: for accurate calibration:
•
The speed from a GPS receiver should be
greater than 5 knots.
To change the units between °F (Fahrenheit) or °C
(Celsius), see section 3-6 Setup > Units.
•
The speed from another paddlewheel trans-

Calibrating the fuel usage can improve the ac-
curacy of fuel measurements.
Twin engine installations require each fuel trans-
ducer 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

2. Connect the portable 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 origi-
nal 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 instructions supplied with it. Then
see Appendix B - Troubleshooting.

4 Using the FISH 4500/4600
This section explains how to interpret the
sonar displays, when and why to use the dif-
ferent 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 4500/4600
works.
4-1 Interpreting the display
The sonar displays do not show a fixed distance
travelled by the boat; rather, they display a his-
tory, 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 de-
pends 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 cov-
ered 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 bot-
tom.
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 1000 ft. (300 m) it takes
about 4 minutes for each vertical line of pixels
to move across the display, whereas at 20 ft. (6
m) it takes only about 15 seconds.
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.
•
•
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.
Kelp / Weed
If the boat is anchored, the echoes all come from
the same area of bottom. This produces a flat
bottom trace on the display.
The screen shot shows a typical sonar display
with the Fish symbols turned Off.

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

Cone width
The pulse generated by the FISH 4500/4600
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 50 kHz it is 45°,
whereas at 200 kHz it is 11°. 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 50 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.

4-2 Single and Dual frequency fishfinding
When to use 200 kHz
When to use 50/200 kHz
The 200 kHz frequency is especially suitable
for use in shallow and medium depth water,
typically less than 500 ft. (150 m) and while
running at speed.
Operating the FISH 4500/4600 at both 50 kHz
and 200 kHz simultaneously on a split display
can be very useful when operating in shallow to
medium water, typically less than 500 ft. (150 m),
because the 50 kHz section of the display shows
the general area, while the 200 kHz section can
be viewed simultaneously for a more detailed
look at any interesting feature.
At 200 kHz, the narrow cone reduces any noise
caused by air bubbles.
The 200 kHz frequency generates a higher
definition pulse which produces little shadow and
returns excellent detail over a small area of bottom.
Therefore, it gives excellent bottom discrimination
capability and is particularly good at showing indi-
vidual fish, including bottom dwellers.
Mixed frequency
The Mixed frequency combines the 200 kHz and
the 50 kHz echoes on one sonar display, filling in
detailed echoes in the centre of the sonar cone.
Mixed frequency
When to use 50 kHz
The 50 kHz frequency is particularly suitable for
use in deep water, typically greater than 500 ft.
(150 m).
At 50 kHz, the cone covers an area of water
about four times wider than the 200 kHz cone
and penetrates to a greater depth with minimal
loss of the return signal.
However, it produces a lower definition display
with more shadow compared to the 200 kHz
frequency. This means that a group of small fish,
for example, could be displayed as a single item,
while any fish very close to the bottom may not
be found at all.
Narrow angle,

200 kHz cone
Wide angle,

This frequency is useful for getting a deep, wide
overview of the area so that any areas of interest
can be identified and then examined in detail with
the 200 kHz frequency.

4-3 Fish detection and display
Fish symbols Off
Where to find fish
For experienced users this always provides the
best information as every echo is displayed, wheth-
er 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.
Underwater features like reefs, wrecks and rocky
outcrops attract fish. Use the 50 kHz or 50/200 kHz
frequency display to find these features, then look
for fish by passing over the feature slowly several
timesusingtheZoomdisplay(seesection5-2Sonar
Zoom display). If there is a current, the fish will often
be found downstream of the feature.
WhenfishingwiththeFISH4500/4600withtheFish
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.
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 50 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 progres-
sively 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 progres-
sively weaker and deeper echo.
Fish symbols
The fish symbol can be customized or switched
off altogether so that the echoes are not con-
verted to fish symbols on the display. See section
3-2 Setup > Sonar. The differences between Fish
symbol Onand 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 differenti-
ate between
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.
• 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 in-
creases 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 4500/4600. Understand-
ing how to set suitable Gain settings is important
for optimum performance.
The Navman fishfinder has two gain modes,
Auto Gain and Manual Gain. Normally the best
results are obtained in Manual Gain, but practice
and experience are required to obtain the opti-
mum settings for different conditions. Therefore,
the use of Auto Gain is strongly recommended
when learning to use the fishfinder or when
travelling at speed.
Note: The Gain mode
automatically changes
to Manual Gain if the gain
or threshold settings are
adjusted by the user
•
In Auto Gain, the gain adjusts automati-
cally to compensate for water depth and
clarity.
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.
•
In Manual Gain, the gain can be adjusted
by the user to compensate for water depth
and clarity.
High Gain settings may amplify the normal back-
ground noise until it appears as random pixels.
Changing between Auto and Manual

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 recom-
mended for normal conditions.
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.

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.
The user can define the level of the weakest and
strongest echoes to be shown on the sonar dis-
plays, by using the Gain and Threshold settings.

of the echo that it returns on the A-scope. Then,
when that particular echo is seen at future times

Economy is 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.

while underway.
There are two mounting arrangements:
•
Protected from physical damage during
rough sea passages.
•
Flush mounting requires a solid panel with
access behind for wiring and mounting screws.
After flush mounting, the FISH 4500/4600
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.
•
Easy to access the 12/24VDCpower 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.
2. Drill four holes for the mounting studs using
the flush mount template.
•
Bracket mounting requires a panel for mount-
ing 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
so the FISH 4500/4600 can be removed after
each use.
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.

6-6 Systems of several instruments
Several Navman instruments can be connected
together to share data.
The FISH 4500/4600 is particularly suited to
work with the TRACKER 5500/5600 - Navman’s
color display GPS chartplotter with worldwide
coverage.
of instruments. Then, if the backlight setting
is changed in one group, it will automatically
change for the other instruments in that group.
However, the backlight setting will not change
for instruments in different groups.
•
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.
NavBus
NMEA
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:
NMEA is an industry standard for marine instru-
ment 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.
•
If the units, alarms or calibration are changed
in one instrument, then the values will au-
tomatically change in all instruments of the
same type.
Please contact your Navman dealer for informa-
tion on Navman’s full range of NMEA enabled
instruments and connection options.

6-7 Cleaning and maintenance
To optimize performance, avoid walking on or
jamming cables and connectors. Keep the trans-
ducer 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.
The FISH 4500/4600 screen is covered by a
proprietary anti-reflection coating. 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.
When not in use, the FISH 4500/4600 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.
Cover or remove a transom-mounted trans-
ducer 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.

Appendix C - Troubleshooting
This troubleshooting guide is written with the as-
sumption that the user has read and understood
the relevant sections in this manual.
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 cor-
roded. Test the fuse or replace it with a fuse
known to be good.
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 serviceable parts. Specialized
methods and testing equipment are required to
ensure that the display unit is reassembled cor-
rectly 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:
2. The fishfinder won’t turn off:
The fishfinder may have been wired forAuto
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 op-
tions.)
3. The fishfinder operates erratically:
a) Check that the transducer does not have de-
bris (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 posi-
tion. (See the Transom Transducer Installation
Guide.)
1. The fishfinder won’t turn on:
a) The FISH 4500/4600 is designed to operate
on a 12/24 volt battery system, where the
voltage may vary from 10 to 35 volts. If an
excessive voltage is supplied, a fuse will be
tripped, turning the display unit off. Check
the fuse.
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 bub-
bles through cavitation. (See the Transom
Transducers Installation Guide.)
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 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:
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.
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.
-
the battery terminals or wiring on the
terminals may be corroded.
the battery may not be charging cor-
rectly 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 battery terminal. If wired for
theAuto 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).
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
