DUAL-RADAR SUPPORT

Using dual radar provides redundancy and allows each display unit on the boat to pull data from one of two different radar sources.

DYNAMIC AUTO GAIN

Gain automatically adjusts levels to optimum settings.

DYNAMIC SEA FILTER

Radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions.

RADAR OVERLAY

Overlay radar images onto your chartplotter’s map page. You can add an optional autopilot or heading sensor (sold separately) for best results.

MARPA TARGET TRACKING

MARPA tracks selected targets to help keep track of other vessels and avoid collisions (with appropriate sensors, sold separately).

LOW-NOISE SCANNING

The reliable GMR HD3 dome drive motor spins at a fixed 24 rpm, offering reliable, low-noise operation and minimal power consumption.
