Garmin GMR Fantom 4 CHIRP Radar System with 4ft Open Array
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The GMR Fantom 4 (4 ft open array) delivers solid-state CHIRP pulse-compression performance with 50 W of peak power, approximately equivalent to a 6 kW magnetron. This combination provides excellent close-in and long-range detection while running cooler and using less energy than a traditional magnetron radar.
MotionScope Doppler technology highlights moving targets in colour, making it easy to identify potential collision threats, flocks of birds and approaching weather at a glance. Auto Bird Gain optimises gain to reveal feeding birds, while MARPA tracks up to 10 targets simultaneously for confident situational awareness.
The open-array form factor combines a compact pedestal with a 4 ft array that rotates at up to 48 RPM for fast target updates. Dual-range scanning with overlay lets you watch near and far at once, all controlled through a compatible Garmin chartplotter over BlueNet or the Garmin Marine Network. The system is rated to IPX6 and withstands winds up to 80 kn.
