automatically adjusted to keep the area above and below the bottom on the
display. Select Off to return to normal operation.

manual depth ranges are determined by the present depth conditions.

Chart Speed determines the speed at which the sonar information moves
across the display, and consequently the amount of detail shown.
A faster speed shows more information and is preferred by most anglers;
however, the sonar information moves across the display quickly. A slower
speed keeps the information on the display longer, but the bottom and fish
details become compressed and may be difficult to interpret.
