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.
