FasTrack gives you a rapid update of conditions directly under the
boat, making it useful for ice fishing or when fishing at anchor. When
the boat is not moving, fish signals are long, drawn out lines on a nor-
mal display. FasTrack converts the graph to a vertical bar graph that
makes a useful addition to fishing at a stationary location.
