Sonar Fishfinder

When properly connected to a compatible transducer, your

ECHOMAP Plus device can be used as a fishfinder.

For more information about which transducer is best for your

needs, go to garmin.com/transducers.

Different sonar views can help you view the fish in the area. The

sonar views available vary depending on the type of transducer

and sounder module connected to the chartplotter. For example,

you can view Garmin ClearVü

compatible Garmin ClearVü transducer connected.

There are four basic styles of sonar views available: a full-

screen view, a split-screen view that combines two or more

views, a split-zoom view, and a split-frequency view that

displays two different frequencies. You can customize the

settings for each view in the screen. For example, if you are

viewing the split-frequency view, you can separately adjust the

gain for each frequency.

If you do not see an arrangement of sonar views to suit your

needs, you can create a custom combination screen

Split-Frequency Sonar View

In the split-frequency sonar view, one side of the screen shows

a full-view graph of high frequency sonar data, and the other

side of the screen shows a full-view graph of lower frequency

sonar data.

NOTE: The split-frequency sonar view requires the use of a

dual-frequency transducer.

Split-Zoom Sonar View

The split-zoom sonar view shows a full-view graph of sonar

readings, and a magnified portion of that graph, on the same

screen.

Garmin ClearVü Sonar View

NOTE: To receive Garmin ClearVü scanning sonar, you need a

compatible chartplotter or fishfinder and a compatible

transducer. For information about compatible transducers, go to

garmin.com/transducers.

Garmin ClearVü high-frequency sonar provides a detailed

picture of the fishing environment around the boat in a detailed

representation of structures the boat is passing over.

Traditional transducers emit a conical beam. The Garmin

ClearVü scanning sonar technology emits two narrow beams,

similar to the shape of the beam in a copying machine. These

beams provide a clearer, picture-like image of what is beneath

the boat.

SideVü Sonar View

NOTE: Not all models provide built-in SideVü sonar support. If

your model does not provide built-in SideVü sonar, you need a

compatible sounder module and compatible SideVü transducer.

If your model does provide built-in SideVü sonar, you need a

compatible SideVü transducer.

SideVü scanning sonar technology shows you a picture of what

lies to the sides of the boat. You can use this as a search tool to

find structures and fish.
