Open the sonar view for which you will change the source.

Select MENU > Sonar Setup > Source.

Select the source for this sonar view.

Renaming a Sonar Source

You can rename a sonar source to easily identify that source.

For example, you use "Bow" as the name of the transducer on

the bow of your boat.

The source is renamed for the present view only. For example,

to rename the Garmin ClearVü sonar source, you must open the

Garmin ClearVü sonar view.

From the sonar view, select MENU > Sonar Setup > Source

> Rename Sonar Sources.

Enter the name.

Adjusting the Level of Detail

You can control the level of detail and noise shown on the sonar

screen either by adjusting the gain for traditional transducers or

by adjusting the brightness for Garmin ClearVü transducers.

If you want to see the highest intensity signal returns on the

screen, you can lower the gain or brightness to remove lower

intensity returns and noise. If you want to see all return

information, you can increase the gain or brightness to see more

information on the screen. This also increases noise, and can

make it more difficult to recognize actual returns.

From a sonar view, select MENU.

Select Gain or Brightness.

Select an option:

• To increase or decrease the gain or brightness manually,

select Up or Down.

• To allow the chartplotter to adjust the gain or brightness

automatically, select an automatic option.

Adjusting the Color Intensity

You can adjust the intensity of colors and highlight areas of

interest on the sonar screen by adjusting the color gain for

traditional transducers or the contrast for Garmin ClearVü and

SideVü/ClearVü transducers. This setting works best after you

have adjusted the level of detail shown on the screen using the

gain or brightness settings.

If you want to highlight smaller fish targets or create a higher

intensity display of a target, you can increase the color gain or

contrast setting. This causes a loss in the differentiation of the

high intensity returns at the bottom. If you want to reduce the

intensity of the return, you can reduce the color gain or contrast.

From a sonar view, select MENU.

Select an option:

• While in the Garmin ClearVü or SideVü sonar view, select

Contrast.

• While in a Panoptix LiveVü sonar view, select Color Gain.

• While in another sonar view, select Sonar Setup >

Advanced > Color Gain.

Select an option:

• To increase or decrease the color intensity manually,

select Up or Down.

• To use the default setting, select Default.
