GMR Features



Motionscope Technology

Detect and highlight moving targets in different colours to help avoid collisions, find flocks of birds and track weather from 20 feet to 96 nautical miles.

Automatic Acquisition

New mini-automatic radar plotting aid (MARPA) automatic acquisition allows for triggering and tracking of up to 30 targets with no user prompting on all returns, boundary zones, guard zones or MotionScope.

Clear The Way

Scan-to-scan averaging aids in reduction of sea clutter and interference, so you have a clear view of what’s out there.

Auto Bird Gain

Where there are birds on the water’s surface, there are fish below it. Auto Bird Gain helps you locate flocks of birds at the water’s surface.

Pulse Compression

This feature provides high-resolution imaging while maximising energy to enhance target detection and identification.

Echo Trails

True Echo Trails feature displays a fading trail to help you quickly and easily identify moving targets while accounting for the movement of your own boat.

Radar Overlay

Overlay radar on your chart screen as single display or split screen with independent range settings.

Dynamic Sea Filter

Dynamic Sea Filter automatically adjusts gain to calm, medium and rough sea conditions.

 Guard Zone

Set the safety zone, and receive an alarm when an object enters the zone.
