Description
Sea gain presets:
• Harbor — this is the
default mode. This
setting takes account
of land clutter so that
smaller targets, like
navigation buoys, are
not lost.
• Coastal — accounts
for the slightly higher
levels of sea clutter
you might encounter
out of harbor and
adjusts the radar
display accordingly.
• Offshore —
Automatically adjusts
for high levels of sea
clutter.
• AUTO — the preset
operates in fully
automatic mode. This
is the default.
• MAN — allows you to
manually adjust the
intensity of the sea
gain, from 0 to 100%.
Enable you to quickly
select pre-configured
settings to achieve the
best picture in different
situations. Each of the
gain presets has a gain
function, which is set
to fully automatic mode
by default. Raymarine
strongly recommends
the use of these presets
to achieve optimum
results. However, you
can adjust this gain
manually if required.
