function, which is set to 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.
• Auto Sea Mode
• 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.
