Meet the Garmin GMR Fantom 54 Radar—a 50-watt, 4-foot open-array radar finished in white, designed to deliver confident navigation in any condition. Paired with a pedestal, it provides rapid, reliable target detection and a clear view of land, vessels, birds, and weather so you can steer with precision and peace of mind.
-
Transmit power: 50W of pulse compression power output, approximately equivalent to a 6kW magnetron.
-
Antenna length: 48" (121.92 cm) open-array antenna.
-
Beam width: 1.8° horizontal and 23° vertical for high-definition imaging.
-
Maximum and minimum range: 72 nautical miles maximum range and 6 meters minimum range.
-
Rotation speed: Adjustable 24 or 48 RPM (high-speed mode available under specific conditions).
-
Radar imaging: High-definition target separation with less screen clutter; Echo Trails provide a fading path of moving targets.
-
Target tracking and safety: MARPA target tracking (requires a heading sensor) and guard zone alarm.
-
MotionScope and dynamic filtering: MotionScope Doppler detects moving targets; Auto Bird Gain, Dynamic Auto Gain, and Dynamic Sea Filter optimize performance in varying conditions.
-
Display and overlay: Overlay on chartplotter view; radar can be shown on a single display or split screen with independent range settings.
-
Compatibility and integration: Dual radar support for redundancy or data fusion with other Garmin radars.
-
Durability and operating conditions: IPX6 water rating; max wind speed 80 kt; operates on 10–32 V DC.
-
