Garmin has released its new GMR Fantom 18 and 24 solid-state pulse compression radomes that offer MotionScope Doppler technology and 40W of power – the highest in the industry for its kind.

The 18” and 24” domes bring Garmin’s GMR Fantom technology to a smaller size and lower price point, making them an attractive option for boats where open-array radar isn’t an option.

Changing the way boaters use radar, Garmin GMR Fantom technology uses Doppler processing to detect moving targets in real time. This not only helps skippers avoid potential collisions but it also enables them to find birds when fishing and track weather. Upon detection, MotionScope highlights moving targets on the radar display with an easy-to-see colour so users can navigate around other boats or severe weather. Auto Bird Gain also allows boaters to easily locate birds at the water’s surface, indicating the presence of game fish.

When the Echo Trails setting is turned on, a fading ‘trail’ on the screen can help easily identify the direction of the moving targets and potential collision threats. The trails shown are also corrected for the boat’s rotation when an autopilot or heading sensor is connected to the Garmin Marine Network.

With its pulse compression technology, the GMR Fantom 18 and 24 provide high resolution while maximising energy to enhance target detection. Pulse expansion can then maximise target size to help differentiate real targets from noise. The Fantom 18 features a 5.2-degree beam width, while the Fantom 24 offers a narrower 3.7-degree width that paints a very precise, high-resolution image.

Both GMR Fantom radomes offer range performance from 6m to 48 nautical miles, without compromise in reliability. Thanks to the dual range feature, it can show both close- and long-range simultaneously, with an overlay on a chart for one or both ranges. This eliminates the need to toggle between views, and allows the skipper to keep a close eye on immediate surroundings and those on the horizon enabling things like weather patterns or land and structure to be constantly observed.

Both models also are very energy efficient (they use less than 25W) and have instant turn-on so no warm-up time is needed, enabling users to start tracking targets instantly. With dual radar support, radomes can also be used with an open-array, GMR xHD2 open array, or GMR xHD dome radar to provide radar redundancy and more flexibility to view different data on independent display units.

Dynamic Auto Gain and Dynamic Sea Filter continually adjust to provide optimal performance and reduce excess noise and clutter, while MARPA settings enable the tracking of 10 targets simultaneously.

The GMR Fantom 18 and 24 are compatible with the new GPSMAP 752/952 and 1022/1222 series, as well as the GPSMAP 7400, 8000 and 8400 series. They are priced from $2999.
