4.22.1Bottom 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 bottom condition on the screen, you may prevent the net from being damaged by a reef or a shipwreck.
