The gain setting controls the sensitivity of the sonar receiver to 

compensate for water depth and water clarity. Increasing the 

gain shows more detail, and decreasing the gain reduces screen 

clutter.

all the views.

NOTE: To set the gain on the split-frequency screen, you must 

set each frequency separately.

right side of the screen. Automatic ranging keeps the bottom 

within the lower third of the sonar screen, and can be useful for 

tracking the bottom where there are slow or moderate terrain 

changes.
When the depth changes dramatically, like a drop off or cliff, 

manually adjusting the range allows a view of a specified depth 

range. The bottom is shown on the screen as long as the bottom 

is anywhere within the manual range established.

From a sonar screen, select 

 > Range.

Select an option:
• To allow the device to adjust the range automatically

You can set the rate at which the sonar image moves across the

aspect ratio and appear less distorted. When viewing 

Garmin ClearVü or SideVü sonar views, it is recommend 

to use the Auto setting.
