Fish I.D.
The Fish I.D. feature displays — as fish — targets that meet certain
conditions. The microcomputer analyzes all echoes and eliminates sur-
face clutter, thermoclines and other undesirable signals.
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.
Fish I.D., the default setting for your unit, is an easier way for a sonar
novice to recognize a fish signal return when he sees it. But, locating
fish by symbol only does have some limitations.
