Changing the depth settings

Color bar #2 is similar but with fewer
•
colors, to aid visibility under some
conditions.
Color bars #3-8 are additional
•
variations with different background
colors.
Color bar #9 uses a monochrome scale,
•
ranging from dark to bright.
You can adjust the shallowest and deepest
echoes to be shown on the
screen. In automatic mode, the echo
sounder sets these values based on its
current environment. However, you can
manually override these auto values for
your specific needs at any time. There are
two depth settings:
shift (how far below the surface the
•
echo sounder picture starts)
range (the depth covered by the echo
•
sounder picture from the top of the
screen to the bottom of the screen)
