an Arrow key. 

The following settings reset to the system defaults each time 

you turn on the Fishfinder.
Range—sets the maximum depth that you want the 

Fishfinder to display. Auto (default) automatically tracks 

the bottom, or you can set the range, 5–600 feet.
Gain—controls the sensitivity of the Fishfinder’s sonar 

receiver. Auto (default) automatically sets the sonar 

sensitivity, or you can set the gain. 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.
