The Sonar adjustment menu contains the following options:

•  Gain—controls the sensitivity of the sonar receiver. Auto (default) is the 

recommended setting. It automatically sets the sonar sensitivity. You can 

also set the gain manually. To see more detail on the screen, increase the 

receiver sensitivity by selecting a higher gain. If there is too much detail or 

if the screen is cluttered, lower the sensitivity (lower the gain) to increase 

the clarity of the screen. If Frequency is set to Dual, you can set the Gain 

separately for each frequency (50 kHz and 200 kHz).

•  Color Gain—controls what colors are applied to the objects on the screen. 

Auto (default) is the recommended setting. It automatically sets the 

colors, based on your Auto Color Gain setting. You can also set the Color 

Gain manually. If Frequency is set to Dual, you can set the Color Gain 

separately for each frequency (50 kHz and 200 kHz).

•  Whiteline—controls how the unit shows information about the bottom 

type (hard or soft). With the Whiteline Off, the bottom return shows as red 

and contains no information on bottom hardness. With Whiteline set at 

Normal or 1-100%, the bottom return becomes white with a red line, in the 

default color scheme, indicating where the water meets the bottom. To turn 

the Whiteline Off, press the 

ROCKER down until the setting bar is all the 

way at the bottom of the range and reads Off.
