The Flasher page displays sonar information on a circular depth scale,
indicating what is beneath your boat. It is organized as a ring that starts at
the top and progresses clockwise. Depth is indicated by the scale inside the
ring. Sonar information ashes on the ring when it is received at the depth
indicated. The colors indicate different strengths of the sonar return (refer to
the table on page 2).
