The Fishnder case is constructed of high-quality materials and

does not require user maintenance except cleaning.

Cleaning the Case

Clean the Fishnder’s outer casing (except for the screen) using

a cloth dampened with a mild detergent solution. Wipe it dry.

Avoid chemical cleaners and solvents that can damage plastic

components.

Cleaning the Screen

Apply eyeglass lens cleaner to a clean, lint-free cloth, and then

gently wipe the screen with the moistened cloth.

The Fishnder 340C lens is coated with a special

anti-reective coating which is very sensitive to skin oils,

waxes, and abrasive cleaners. CLEANERS CONTAINING

AMMONIA HARM THE ANTI-REFLECTIVE COATING.

Storage

Do not store the Fishnder where prolonged exposure to

temperature extremes might occur (such as in the trunk of a car),

because permanent damage can result.

Water Immersion

The Fishnder is waterproof to IEC Standard 60529 IPX7. It can

withstand immersion in 1 meter of water for 30 minutes. Prolonged

submersion can cause damage to the Fishnder. After submersion,

wipe and air dry the Fishnder before reusing.

Understanding the Fishnder and Sonar

The Fishnder 340C is a fully automatic, color sonar unit that

allows you to go out on the water and nd sh without having

to congure a lot of settings. However, you can customize each

setting as you prefer.

If you have used a Fishnder 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 Fishnder before, you might

want to learn a bit about sonar: what it is, how it works, and what

you might see on the Fishnder 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 nd the sh.

Understanding Sonar

During installation, you connect your Fishnder 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 Fishnder 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 ashlight beam (covering a smaller circular area

at the top and angling out to a larger circular area at the bottom).

These sound waves reect off of any object that they hit, and then

the waves travel back up to the transducer. These objects could

be sh, 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 Fishnder.

The Fishnder 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.

Fishnder 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 shing 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 Fishnder Screen

Experimentation and experience are the keys to successfully

interpreting your Fishnder screen. We recommend that you take

your Fishnder out on familiar water, and spend time learning to

interpret what you see on the Fishnder 340C screen.

Think of the Fishnder screen as if you took a picture from the

side of an aquarium in your home. You can see how deep a sh is

in the water (how close it is to the top or bottom), but you cannot

tell where the sh 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 Fishnder 340C includes the latest technology in

interpreting bottom signals; it can see through sh, structures, and

thermoclines (shown in the weakest colors). Large schools of sh

or dense structures close to the bottom can affect water depth return

readings.

If the Fishnder is unable to track the bottom for any

reason, the digits which indicate depth ash on and off to alert

you that the Fishnder 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 sh. 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, sh orientation, or other

conditions. You can turn on the Fish Symbols setting if you want to

see suspended targets indicated by a sh 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.
