The powerful 4-kilowatt Garmin GMR 18 Digital Marine Radar Scanner is clearly a breakthrough in X-band digital radar design. Its space-saving 18-inch radome with self-contained signal processing provides the ideal "plug-and-play" addition to your Garmin Marine Network. The Garmin 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. Any compatible Garmin network chartplotter functions as your radar screen. And to aid in hazard avoidance, MARPA target tracking is supported (with optional heading sensor).
