Triple beam display
Side scan display
From the Home screen, tap the Side Scan icon to show the side scan display.
The side scan display shows the echoes received from the port and starboard direc-
tions.
The side scan display starts from the center of the vessel, and traces in the port and
starboard directions. The most recent echoes are at the top of the screen and the old-
est are at the bottom of the screen.
The side scan display is different from the other modes employed by this equipment -
it clearly displays the shape of echoes (fish bed, etc.).
