Chart Speed Setting

Most of the displays on the FishFinder show a record of the signals the
unit has received. The new information appears at the right (or top) edge
of the display. The older information moves toward the left (or bottom) of

display moves. (Notice that the scrolling speed of the display is not

chart speed, the display has more space on the display to show this
section, so it can include more detail. Using a slower chart speed, this
