NAVMAN
4-4 Range
Range is the vertical depth displayed on the
FISH 4350 and FISH 4380.
The Navman
Þ
sh
Þ
nder has two range modes,
Auto Range and Manual Range:
•
In Auto Range, the
Þ
sh
Þ
nder adjusts
the depth range automatically so the
bottom is always shown in the lower part
of the display. The use of Auto Range is
recommended for normal conditions.
•
In Manual Range, the
Þ
sh
Þ
nder shows only
a selected depth range. In areas of rapidly
changing bottom depth, such as the sea
ß
oor around pinnacles, it can be useful
to prevent the display from rescaling to
always show the bottom. If the bottom is
deeper than the speci
Þ
ed depth range, it
will not be shown on the display.
