FasTrack

This feature automatically converts all echoes to short horizontal lines
on the display's far right side. 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.
