The color bar provides an estimate of echo strength in 16 colors. The
red color is the strongest echo signal.
The depth scale and range scale provide an estimate of depth and
range in the echosounder and audio displays, respectively. It may be
displayed at the right or left side of those displays. See COMBI SCALE
on the SYSTEM menu.
The cross-hair cursor measures the depth and range to the user-
selected location in the echosounder and audio displays, respectively.
Depth or range appears at the cross-hair cursor intersection.
The net sonde marks are orange horizontal lines (solid or dashed line)
which mark the location of the net sonde fed from the echosounder.
