Understanding the Flasher Screen
The Flasher screen (dual beam transducer only) provides an almost
instantaneous return of what is below your boat. The depth scale is
organized as a ring that starts at the top, or 12:00, and progresses
clockwise. Sonar information ashes on the ring when it is received
at the depth indicated on the inside ring. Like the regular graph, The
colors indicate different strengths of the sonar return.
On the Home screen, highlight Flasher, and press SELECT.
