FISH l.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 l.D. feature

displays symbols on the

screen in place

of the actual fish echoes. There are four fish

symbol

sizes:

tiny, small, medium, and large. These are used to designate the relative

size between targets.

In other words, it

displays

a small fish

symbol when
