FISH I.D.
The Fish I.D.
feature identifies targets that meet certain conditions
as fish. The microcomputer analyses all echoes and eliminates surface
clutter, thermoclines and other signals that are undesirable. In most
instances, remaining targets are fish.
The Fish I.D. feature displays symbols on the screen in place of the ac-
tual fish echoes. There are three symbol sizes: small, medium, and
large. These show the relative size between targets. In other words, it
displays a small fish symbol when it thinks a target is a small fish, a
medium fish symbol on a larger target and so forth.
At left, underwater scene in normal fish arch mode. Right, Fish I.D.
menu with the feature turned on.
