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