4.22 How to Interpret the Slant Display
4.22.1 Bottom echoes
When the tilt angle is set at 90 degrees with the sector center faced dead ahead, the
pictures illustrated below will appear on the screen. The bottom echo is represented
on the screen as a thick line which realistically shows the bottom contour. When the
tilt angle is decreased, the bottom trace becomes wider and weaker. By observing bot-
tom condition on the screen, you may prevent the net from being damaged by a reef
or a shipwreck.
