FasTrack

This feature automatically converts all echoes to short horizontal lines on the right side of the display. The graph on the rest of the screen con- tinues to operate normally. FasTrack gives you a rapid update of condi- tions directly under the boat. This makes it useful for ice fishing or when your are fishing at anchor. When the boat is not moving, fish sig- nals are long, drawn out lines on a normal chart display. FasTrack con- verts the graph to a vertical bar graph that with practice, makes a use- ful addition to fishing at a stationary location.

Fish I.D.

The Fish I.D. feature identifies targets that meet certain conditions as fish. The microcomputer analyzes all echoes and eliminates surface clutter, thermoclines and other undesirable signals. In most instances, remaining targets are fish. The Fish I.D. feature displays fish symbols on the screen in place of actual fish echoes.

There are several fish symbol sizes. These are used to designate the relative size between targets. Fish I.D. displays a small fish symbol when it thinks a target is a small fish and a medium fish symbol on a larger target and so on.
