The Fishfinder 160 is able to display a variety of useful information
about the underwater environment. Below are a few things the unit will
help you see.
Introduction
Water Depth
What can the Fishfinder 160
Display?
The unit displays water depth and can provide a warning for shallow
or deep-water conditions.
Battery Voltage
The unit can display the battery voltage that is available to the unit.
Water Temperature*
If equipped with a capable transducer, the unit can display the water
temperature.
Speed Over Water*
If equipped with a capable transducer or Speed Sensor, the unit can
display the boat’s speed over water.
Fish
The unit displays fish as arches or fish symbols and can alert you when
a fish is detected.
Thermocline and Structure
With GARMIN’s See-Thru® technology the Fishfinder 160 can display
more than just the thermocline and structure, the unit displays fish
in and below the thermocline, trees, brush and deadfall like you have
never seen before!
Bottom Shape and Type
Garmin’s unique DCG® (Depth Control Gain) system provides a clear
graphic representation of the bottom type and its shape.
* requires optional transducer or sensor

Transducers
The transducer acts as the eyes and ears of your new sonar. Proper
transducer selection and installation are critical to the operation of your
unit.
The transducer transmits sound waves toward the bottom in a cone
shape. The larger the cone angle the larger the coverage area at a given
depth. While it is good to see as large of an area as possible, it is best to
select a transducer that suits the water that you are on.
A wide cone angle transducer works best in shallow water. The wide
cone angle provides a large coverage area, but at a decreased bottom
resolution. In deeper water this can result in a large dead zone where
fish cannot be seen.
A narrow cone angle transducer is better suited to deep-water installations. The narrow cone angle provides a smaller viewing area (compared
to a wide cone angle transducer at the same depth) with improved bottom
resolution and a smaller dead zone.
Included in the Optional Package is a 20° cone angle, temperature sensing, transom mount transducer. This transducer provides good all-around
performance. A variety of optional transducers are available from your
local dealer or GARMIN.

Proper transducer installation is key to getting the best performance
from your new unit. If the transducer lead is too short, extension cables
are available from you GARMIN dealer. DO NOT cut the transducer lead,
this will void your warranty.
Installation
Following are some tips and basic installation instructions for three popular transducers. Detailed installation instructions are provided in the transducer kits.
Mounting the Transducer
Transom Mount Installation
DO NOT mount the transducer behind strakes,
struts, fittings, water intake or discharge ports, or
anything that creates air bubbles or causes the
water to become turbulent. It is important that
the transducer be in calm, non turbulent water for
optimal performance.
010-10248-00 (depth/temp) Transom Mount Transducer.
Apply marine sealant to all
screw threads to prevent water
from seeping into the transom.
Mount the transducer cable cover
well above the waterline.
Transducer should extend 1/8" below
fiberglass hull or 3/8" below aluminum hull
OK
Make sure that the transducer is
below water level when the boat
is on plane at high speed
Do not mount transducer directly in the
path of the prop. The transducer can cause
cavitation that may degrade the boat's performance
and damage the prop.
Mount the transducer parallel with the bottom.

10/19/00, 2:17 PM
In-hull Installation
The 010-10224-00 transducer is designed to be mounted inside a
fiberglass hull. The standard plastic transom mount transducer can also be
mounted in this fashion using this method. If using a temperature sensing
transducer, the temperature displayed will reflect the hull temperature.
Selecting a Location
Installation
Mounting the Transducer
The location has to be solid fiberglass, devoid of any air bubbles,
laminates, fillers or dead air space. The location needs to be in an
area of clean water at all speeds. Do not place the transducer over
any strakes or behind any obstruction on the hull that would create
turbulence at speed.

Many modern hulls have a prelocated pocket for In-hull transducer installation.
If you are unsure if your hull is equipped with a prelocated pocket, contact
your hull manufacturer.
Strip Caulk or
RTV Sealer
Hull Surface
Testing the Location
Place the transducer in the water, pointed directly at the bottom and set
unit for optimum performance. Place the transducer in the test device as
show on the side bar. If the sonar performance is significantly degraded,
another location will need to be tested.
Testing the Location
Apply twisting motion
to eliminate any
trapped air bubbles
Weight transducer in place
for at least 24 hours
Slow cure two
part epoxy
Installing the Transducer
1. Lightly sand the surface of the hull and face of the transducer with 400
grit wet or dry sandpaper.
2. Build a dam using strip caulk about 1/4” tall. Pour about 1/8” of two
part, slow cure epoxy in the dam. Place the transducer in the epoxy,
turning the transducer to work out any air bubbles.

10/19/00, 2:18 PM
Testing the Installation
While it is possible to perform some checks with the boat trailered, to
properly test the installation the boat should be in the water.
Press the Power button and the Fishfinder 160 should power on. If the
unit fails to power on, verify that the wiring adapter is seated properly in
the back of the unit, the Red and Black wires are connected to the correct
polarity, and that the 2-Amp fuse is installed and not blown. If the unit is
connected to a power supply that exceeds 18 VDC, a ‘Battery Voltage High’
warning will be displayed and the unit will turn off.
Installation
Testing the Installation
As the unit powers on, it should immediately start showing the bottom.
Verify that the unit is not in the simulator mode. If the unit is in the
simulator mode, make sure that the transducer is connected to the wiring
harness.
To test the transducer installation, gradually increase the boat speed
while checking the unit operation. If the unit displays intermittently or
fails to display, verify that the transducer is aligned parallel with the bottom
and if necessary, adjust the transducer height until the unit operates
correctly. It may be necessary to make several adjustments to ensure proper
operation throughout the speed range.
When adjusting the depth of the transducer, make the adjustments in small increments. Placing the transducer too deep can adversely affect the boat’s performance
and place the transducer at greater risk of striking underwater objects.

Understanding Sonar
If you are familiar with sonar, and can determine what is on the chart,
this section may not be for you. This section is intended to help the novice
user gain some understanding of how the Fishfinder 160 operates and how
it can help improve their fishing productivity.

This fish is currently in a Dead Zone and is not detected
by the sonar. The fish is in the coverage area of the
transducer, but remember the first strong return sets the
bottom level. The fish will never be detected since the
bottom level will never be set below the fish. The fish
on the right side of the display (shown in light grey) will
be detected and displayed when the transducer cone
passes over the fish.
To understand what the unit is displaying, it is important to have a
general knowledge of how the unit works and how it determines what to
display. Briefly described, the unit operates by transmitting sound waves
toward the bottom of a lake, stream or seabed in a cone shaped pattern.
When a transmitted soundwave strikes an underwater object such as the
bottom, a piece of structure, or a fish, sound is reflected back to the
transducer. The transducer collects the reflected sound waves and sends
the data to the unit to be processed and displayed on the chart. The
underwater data is displayed on the chart in the order that it is returned:
first returned—first on the chart. The diagram in the sidebar demonstrates
this showing an underwater scene as it would be displayed on the chart.
Generally speaking, if the only thing between the transducer and the
bottom is water, the first strong return will come from the bottom directly
below the transducer. The first strong return sets the bottom level. Weaker
secondary returns provide the detailed data. Stronger returns will display
in darker colors, black being the strongest return. In Example 2 (page 30)
you can see that the branches and the fish were the strongest secondary
returns and are indicated in black on the display.
That is brief description of how your Fishfinder operates. Let’s take a
look at how this data can help you to improve your fishing.

Transducer Coverage
The area covered by the transmitted sound waves is determined by the
cone angle of the transducer and the water depth. Using Garmin’s standard
20° transducer, the coverage is approximately 1/3rd of the water depth.
As shown in Example 1, the coverage area at a 30 foot depth is approximately a 10 foot diameter circle. The scale below illustrates how coverage
increases as depth increases.

Understanding the Chart
It is important to understand that the unit does not display a 3-D representation of the underwater environment. The unit can display multiple
things at the same time, but can not determine where the return originated
only when it was received.
On the Water
Understanding the Chart
Example 2 provides a look at the underwater world from a top view,
and relates that view to what would be displayed on the chart. On the chart
it appears the fish and tree are side by side, but when we look at the scene
from the top we can see that the fish is several feet from the tree. It is
important to remember that the fishfinder can not determine where in the
coverage area the tree or fish are, only that the returns were received in
the same time frame.

Remember that the Fishfinder displays a 2D picture

Whiteline
The Fishfinder 160 can help you to determine if the bottom is hard
or soft. When the sonar soundwaves are reflected back by the bottom, a
hard bottom will return a stronger signal than a soft bottom. The stronger
bottom return, the wider the bottom layer is displayed. The unit uses
the whiteline function to make this bottom layer information easier to
distinguish.
When viewing the display without Whiteline active, the bottom return
is black. While you can make some determination of the bottom type,
the black return makes this more difficult. With the whiteline active the
bottom return appears layered in shades of gray and black and makes
determining the bottom type easier and more reliable. Example 3 shows
the bottom return with and without the whiteline activated.

Understanding the Chart
Whiteline can also help you to determine the type
of bottom structure that is displayed on chart. By
determining the hardness of the structure you can
make a better informed decision on the type of
structure.

Thermoclines
On the Water
Understanding the Chart
One of the unique features offered by GARMIN is See-Thru® technology. See-Thru® technology allows the Fishfinder 160 to see through
thermoclines and helps locate fish where they live, and fish love the
thermocline.
A rough definition of a thermocline is a break in water where the water
temperature changes faster than the water above it. The thermocline usually
displays as a gray level as shown below.

Simulator Mode
The Fishfinder 160 comes with a built-in simulator mode that will allow
the user to practice and learn the operation of the unit at home rather
than on the water.
To start the simulator mode, turn the unit on without a transducer
installed. As the unit powers on, the unit will indicate that it is running
the simulator mode by displaying a message across the bottom of the chart.
The message will be replaced by the simulator mode icon in the lower left
corner of the chart. While in the simulator mode, the unit will display a
random bottom scene and the Fishfinder 160 can be controlled just as if
it were on the water.
