The GMR 18 allows you to experience the power of X-band digital marine radar scanning like never before.

Get Powerful performance in a small container

At 18 inches, the 4 kW GMR 18 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 18 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).
