Radar
Dual Range Mode
Dual Range mode provides a side-by-side view of both short-range and long-range radar data, with a GMR
xHD radar. The two radar views provided in this mode can be especially useful at night or in inclement
weather.
Short-range radar data appears on the left side of the dual-range screen, and the signal range cannot exceed
3 nm (4 km). Long-range radar data appears on the right side of the dual-range screen, and the signal range
must be greater than the signal range shown on the short-range screen. The short-range screen is comparable to
Harbor mode, and the long-range screen is comparable to Offshore mode.
Note
: If you switch from Sentry mode to Dual Range mode, the radar switches to full-time transmission and
disables any guard zones. If you switch from Harbor mode or Offshore mode to Dual Range mode, all MARPA
targets are cancelled, and you cannot acquire MARPA targets until you exit Dual Range mode.

Sentry Mode
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 and sounds an alarm when a radar object enters this zone. Sentry mode works with all
GMR models.

Note
: If you switch to Sentry mode and MARPA is disabled in Sentry mode, all MARPA targets are
cancelled, and you cannot acquire MARPA targets until you exit Sentry mode. If MARPA is enabled in Sentry
mode, MARPA targets are not cancelled.
