FasTrack

This feature automatically converts all echoes to short horizontal lines
on the display's far right side. The graph on the rest of the screen
continues to operate normally. FasTrack gives you a rapid update of
conditions directly under the boat. This makes it useful for ice fishing,
or when you're fishing at anchor. When the boat is not moving, fish
signals are long, drawn out lines on a normal chart display. FasTrack
converts the graph to a vertical bar graph that, with practice, makes a
useful addition to fishing at a stationary location.

Fish I.D.
 (Fish Symbols & Depths)
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
fish symbols on the screen in place of the actual fish echoes.
