Radar
Offshore mode—intended for use in open waters, this mode works best with long-range radar
signals.
Dual Range mode—provides a side-by-side view of both short-range and long-range radar data.
Sentry mode—allows you to put the radar into timed-transmit mode, in which you can congure
a radar transmit and standby cycle to conserve power. You can also enable a guard zone in Sentry
mode, which identies a safe zone around your boat.
