Depth line
When toggled on, a line is shown on the bottom surface. The depth line makes easier to
distinguish the bottom from fish and structures.
Amplitude scope
The amplitude scope is a display of an echo sounding on the panel. The strength of the
actual echoes are indicated by both width and color intensity.
Enhanced and horizontal amplitude scope indicators
The enhanced and horizontal amplitude scope show 2 indicators:
A Enhanced amplitude scope image
B Horizontal amplitude scope image
C Cross indicator - indicates where in the echo sounding the bottom is located.
D Threshold line - indicator of the current gain. It tells you the amplitude of the return
echo displayed on the panel. The gain setting helps to distinguish return echoes
between echo targets and noise.
