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 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 you're 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.
