INTERPRETING THE DISPLAY
Seabed Echoes
When the tilt angle is widened, the seabed echo illustrated be-
low will appear on the display. When the tilt is narrowed, the
seabed trace becomes wider and weaker. By observing the sea-
bed condition on the display, the skipper can prevent net dam-
age.
(A) Flat seabed
Tilt angle: 10° to 15°
(B) Flat seabed
Tilt angle: 20° or more
(C) Sloping seabed
Tilt angle: 20° or more

and with a

echo is displayed in
