Get Powerful performance in a small container
At 18 inches, the 4 kW GMR 18 HD High-Definition Radar is twice as powerful as most other radars in its size and price range. Combine that with the antenna’s 5.2° beamwidth, and you’re looking at the best weather penetration and target definition in its class.
Connect to Garmin Marine Network
GMR 18HD has self-contained signal processing that provides the ideal “plug-and-play” addition to your Garmin Marine Network™. Any compatible Garmin network chartplotter can double as your radar screen. And to aid in hazard avoidance, MARPA target tracking is supported (with optional heading sensor).
