Garmin offers a full line of radome and open array radars. Garmin xHD2 radars provide high-definition digital technology delivering high-resolution radar images to your plotter — images that are sharper with even better target separation. Garmin high-definition xHD2 antennas are the future-proof choice when upgrading your Garmin Marine Network.

GMR 18/24 xHD3

Scan Averaging Technology 

A first for Garmin magnetron radar, scan averaging helps filter out sea clutter and interference to enhance the detection and display of consistent targets.

Angular Target-Size Adjustment

Pulse expansion and angular target-size processing techniques optimize on-screen object shapes for better interpretation at all range scales.

Faster Scanning Antenna 

Rotation speeds up to 60 rpm improve the redraw rate for faster target updates.

True Echo Trails

A historical "trail" of boats on the water is displayed on the screen, removing relative motion influences to help you quickly identify moving targets and potential collision threats.

Dual Range with Overlay

A single radar antenna is capable of providing split-screen, side-by-side images on your compatible chartplotter, with independent range settings and controls for both close and long range. Overlay either or both ranges on a chart.

GMR™ Fantom 18

18-inch Dome Radar with MotionScope™ Technology

• 18-inch, 40 W solid-state, dome radar
• MotionScope™ technology uses the Doppler effect to detect and highlight targets moving toward you or away in different colors to help avoid collisions, find flocks of birds, and track weather
• Pulse Compression technology provides high resolution while maximizing energy, to enhance detection and identification of targets
• Target Size allows you to adjust the size of objects on the radar image
• 20 foot to 48 nautical mile detection range

The 18-inch, 40 W solid-state Garmin GMR Fantom 18 dome radar features MotionScope technology, which uses the Doppler effect to detect and highlight moving targets to help you avoid potential collisions. Fully integrates with select Garmin chartplotters.

High-power 40 W Radar with 5.2 Degree Beam

You get excellent close- and long-range target detection ranging from as close as 20 feet to 48 nautical miles, even in fog or rain. Its 5.2 degree horizontal beamwidth provides a high resolution image and high antenna gain so it can pick out targets at a distance. The result is this radar paints a clear, concise image of the shoreline, other vessels and impending weather — right on your Garmin chartplotter. You get consistent target positions, excellent target separation and reliable operation. Its 8-bit true color imagery also helps you discriminate large targets from small ones and enhances target separation. Radar data is overlaid onto charts (autopilot or heading sensor recommended). Low power consumption, instant turn on and no delay from warming up as with magnetron radars. Rotation speeds of 24 for reduced power consumption and 48 rpm to provide fast screen updates.

MotionScope Doppler Technology

GMR Fantom radars use the Doppler effect to detect and highlight moving targets to help you avoid potential collisions, find flocks of birds and track weather formations. The Doppler effect is the frequency shift in the radar echo due to the relative motion of the target. This allows for instant detection of any targets moving toward or away from the radar. MotionScope highlights the moving targets in different colors on the radar display so you can navigate around other boats or severe weather, or toward fishing spots where birds are feeding at the surface.

GMR™ Fantom 24

24-inch Dome Radar with MotionScope™ Technology

• 24-inch, 40 W solid-state, dome radar
• MotionScope™ technology uses the Doppler effect to detect and highlight targets moving toward you or away in different colors to help avoid collisions, find flocks of birds, and track weather
• Pulse Compression technology provides high resolution while maximizing energy, to enhance detection and identification of targets
• Target Size allows you to adjust the size of objects on the radar image
• 20 foot to 48 nautical mile detection range

The 24-inch, 40 W solid-state Garmin GMR Fantom 24 dome radar features MotionScope technology, which uses the Doppler effect to detect and highlight moving targets to help you avoid potential collisions. Fully integrates with select Garmin chartplotters.

High-power 40 W Radar with 3.7 Degree Beam

You get excellent close- and long-range target detection ranging from as close as 20 feet to 48 nautical miles, even in fog or rain. Its 3.7 degree horizontal beamwidth provides a high resolution image and high antenna gain so it can pick out targets at a distance. The result is this radar paints a clear, concise image of the shoreline, other vessels and impending weather — right on your Garmin chartplotter.
