The Garmin GMR Fantom™ 56 Open Array Radar – Black (Part Number: K10-00012-31) is a high-performance, 50-watt solid-state open-array radar package styled in a factory black finish to suit modern vessel profiles while delivering long-range target detection up to 72 nautical miles. Equipped with a 6-foot antenna array, it produces an ultra-narrow 1.25-degree horizontal beamwidth, providing maximum target separation, precise angular resolution, and exceptional image clarity to distinguish small targets and distant landmasses in heavy clutter, fog, or rain. Powered by MotionScope™ Doppler technology, it instantly identifies and color-codes moving targets to highlight potential collision risks, incoming weather, or surface-feeding bird flocks in real time. Operating at dual rotation speeds of 24 RPM for power efficiency and 48 RPM for rapid display refresh rates, the Fantom 56 connects seamlessly with Garmin GPSMAP® chartplotters via the Garmin Marine Network, featuring MARPA target tracking, dual-range overlay, dynamic auto-gain, and pulse expansion controls for offshore navigation.
