The Garmin GMR 18 HD Network Radar brings you the power of X-band digital marine high-definition radar scanning like never before.
GMR 18 HD is a 4 kilowatt radar with 36 nm range. At 18 inches in diameter, it is twice as powerful as most other radars in its size and price range. Combine that with the antenna’s 5.0° beam width and you’re looking at the best weather penetration and target definition in its class.
To help you avoid traffic on the water, the GMR 18 HD provides MARPA target tracking (with optional heading sensor), which allows you to track the bearing, course, speed and predicted closest approach of up to 10 targets. And like all Garmin radars, GMR 18 HD has self-contained signal processing, which provides you with a more precise, easy-to-read signature.
The GMR 18 transmits data over the Garmin Marine Network, a 100-megabit plug-and-play proprietary network that gives you the ability to expand your boat’s system as needed. Once connected to the network, you can use any network-compatible Garmin chartplotter as your radar screen. And as an aid to locational awareness, you can overlay the GMR 18 HD radar image on the chartplotter's map page.
You can also split the on-screen display so that you can view the map and the standard radar page simultaneously.
