Using Sonar

When connected to a transducer, the following chartplotters can be 

used as fishfinders: 
GPSMAP 431s  GPSMAP 441s  GPSMAP 531s 

GPSMAP 536s  GPSMAP 541s  GPSMAP 546s

Select the Full Screen option to view a full-screen graph of the 

transducer’s sonar readings.
From the Home screen, select 

 > 

.

(GPSMAP 431s/531s/536s only) Use the Flasher screen 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.)
