Select Radar.

Cruising Mode

Shows a full-screen image of the gathered radar information.

Harbor Mode

Intended for use in inland waters, this mode works best with short-range signals (2 nm or less).

Offshore Mode

Intended for use in open waters, this mode works best with long-range signals.

Sentry Mode

Allows you to put the radar into timed-transmit mode, in which you can configure a radar transmit and standby cycle to conserve power. You can also enable a guard zone in this mode, which identifies a safe zone around your boat. If you switch from Sentry mode to another mode, the radar switches to full-time transmission and disables all guard zones.

Radar Overlay Mode

Shows a full-screen image of the gathered radar information on top of the Navigation chart. The Radar overlay displays data based on the most recently used radar mode.
