GMR Fantom™ 56 Radar - Black

This open-array radar highlights moving targets in color and gives users excellent close- and long-range target detection — even in fog or rain.


  • Know what’s coming. MotionScope™ technology shows targets in color as they move closer or away
  • GMR Fantom brings the power (50 watts of it)
  • Get high resolution without wasting energy, thanks to pulse compression
  • Add even more detail to maps with radar overlay — even in a split-screen view

High-Powered Radar

This 50-watt radar has a range from 20’ to 72 nautical miles, even in fog or rain. It offers rotation speeds of 24 RPM for reduced power consumption and 48 RPM for fast screen updates.

High-Resolution Radar

The 1.25-degree horizontal beamwidth provides a high-resolution image and high antenna gain to pick out even weak targets at a distance.

Motionscope Technology

MotionScope uses the Doppler effect to detect moving targets and highlight them in different colors so users can navigate around other boats or severe weather — or toward fishing spots where birds feed at the surface.

Intuitive Operation

This radar doesn’t have any complex user settings to deal with, so it’s easy to install and start using.

Target Size

Adjust the size of objects on the radar image.

Auto Bird Gain

Locate flocks of birds at the water’s surface where baitfish are also likely to be found.

Echo Trails

A historical “trail” is left on the screen to help users quickly and easily identify moving targets and potential collision threats.

Dual Range 

A single radar antenna is capable of providing split-screen images on the chartplotter for both close and long ranges.

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 for harbors, near shore, and offshore in open waters.

Dynamic Sea Filter

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

Radar Overlay

Overlay radar images onto the chart plotter’s map page. Users can add an optional autopilot or heading sensor (sold separately) for best results.

MARPA Target Tracking

Mini-automatic radar plotting aid (MARPA) tracks up to 30 selected targets, helping users keep track of other vessels and avoid collisions.

Guard Zone

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


Variable range markers (VRM) and electronic bearing lines (EBL) allow rapid measurements of distance and bearing to vessels and land.
