Bottom range echogram.

BOT. RANGE PRES. in the Display Menu must be enabled. The bottom range
echogram is independent of the main echogram since the range settings are
separate. It will overwrite 20% of the main echogram and may be placed on
different parts of the main echogram. (Refer to DISPLAY/Echogram Menu
description).
The bottom range echogram is separated from the main echogram with a solid
black boundary line. The bottom range echogram is blanked out if no bottom

will feature an excess gain below the detected bottom.
