From the Home screen, select 

 to 

display sonar information on a circular depth 

scale. The scale indicates what is beneath 

your boat. It is organized as a ring that starts 

at the top and progresses clockwise. Sonar 

information flashes on the ring when it is 

received at the depth indicated. The colors 

indicate different strengths of the sonar 

return. (When using the white default color 

scheme, red indicates the strongest return, 

blue indicates the weakest return, and white 

indicates no return.) 

Press 

 to change the range, gain, 

beam, and sonar settings, as described
