GETTING STARTED > UNDERSTANDING THE FISHFINDER AND SONAR
Understanding the Fishfinder and Sonar
The Fishfinder 340C is a fully automatic, color sonar unit that
allows you to go out on the water and find fish without having
to configure a lot of settings. However, you can customize each
setting as you prefer.
If you have used a Fishfinder before, you might already know how
to interpret the sonar information on the screen, so you can skip
this section. If you have not used a Fishfinder before, you might
want to learn a bit about sonar: what it is, how it works, and what
you might see on the Fishfinder 340C screen. This manual provides
a general understanding of those things that you need to know
about sonar that can help you interpret the screen and find the fish.
Understanding Sonar
During installation, you connect your Fishfinder 340C to a
transducer. The transducer uses sound to determine information
about what is in the water beneath your boat. Then the transducer
sends the information to your Fishfinder to be shown on the screen
for you to view and interpret.
The transducer sends sound waves down into the water in a cone
shape, similar to a flashlight beam (covering a smaller circular area
at the top and angling out to a larger circular area at the bottom).
These sound waves reflect off of any object that they hit, and then
the waves travel back up to the transducer. These objects could
be fish, branches, the bottom, or any other object that has density
that is different from the water. The transducer receives the sound
wave information, and then sends the information to the Fishfinder.
The Fishfinder shows the information on the screen for you to see
and interpret. The type of transducer and settings that you choose
determine how the information appears on the screen.
Using Dual Frequency
Dual frequency works best for deep water (for example, off-shore)
applications. The 200 kHz frequency allows you access to great
detail about what is underneath your boat. The 50 kHz frequency
provides less detailed information, but penetrates to greater depths
with the same power. You can choose either or both frequencies to
get the information that you want. If you choose dual frequency,
the transducer alternates between the 50 kHz and 200 kHz signals.
This capability allows you to see the best picture available at any
depth.
Fishfinder 340C Owner’s Manual 3
GETTING STARTED > UNDERSTANDING THE FISHFINDER AND SONAR
Using Dual Beam
Dual beam works best for shallow water (for example, inland)
applications. A dual beam transducer can transmit a narrow or a
wide beam. The water area covered by the transmitted sound waves
is determined by the beam width of the transducer and the water
depth. The narrow beam provides crisp detail of what is under your
boat, and is very helpful if you are fishing in deeper water where
the beam covers more area (for example, at a depth of 30 feet, the
narrow beam covers the area of about a 7-foot circle).
Wide
Beam
Narrow
Beam
The wide beam is more helpful in shallow water, because it gives
you a much wider view of objects in the water, including areas
beyond the sides of your boat. At a depth of 30 feet, the wide beam
covers the area of approximately a 20-foot circle.
Understanding the Fishfinder Screen
Experimentation and experience are the keys to successfully
interpreting your Fishfinder screen. We recommend that you take
your Fishfinder out on familiar water, and spend time learning to
interpret what you see on the Fishfinder 340C screen.
Think of the Fishfinder screen as if you took a picture from the
side of an aquarium in your home. You can see how deep a fish is
in the water (how close it is to the top or bottom), but you cannot
tell where the fish is located horizontally in the water (whether it is
near the front or the back of the aquarium). Remember this when
you are trying to locate exactly where something is in the water.

The strongest sonar returns appear on your screen as the most
intense solid color (depending on your selected color scheme; red
is the default). The weakest returns appear as the less intense, less
solid colors (blue is the default).
The bottom of the water is always going to be the strongest
signal, and therefore the most intense color. The bottom is the
continuous, intensely-colored line running across the bottom of
the screen. The Fishfinder 340C includes the latest technology in
interpreting bottom signals; it can see through fish, structures, and
thermoclines (shown in the weakest colors). Large schools of fish
or dense structures close to the bottom can affect water depth return
readings.
NOTE: If the Fishfinder is unable to track the bottom for any
reason, the digits which indicate depth flash on and off to alert
you that the Fishfinder is not tracking the bottom.
Along the top of the screen, you might see a grouping of intense
colors. This area is surface clutter, which can be caused by waves
or any other sonar interference at the surface of the water. Too
much surface clutter can obscure your view of fish. You can turn
down the Gain setting to reduce this surface clutter.
Between the bottom and the surface clutter, you see suspended
targets in the previous illustration. Here, the targets appear as
arches. Actual suspended target returns might not always appear
as perfect arches, due to the speed, fish orientation, or other
conditions. You can turn on the Fish Symbols setting if you want to
see suspended targets indicated by a fish shape.
The strength of the sonar return can also help you interpret the
hardness of the bottom of the water. The thicker the bottom line,
the harder the bottom.
