GMR™ 18 HD

Sharpen your radar picture with high definition performance. The GMR 18 HD radar offers a whole new level of radar scanning capability.

Get Powerful Performance

The GMR 18 HD features high-powered Digital Signal Processing, providing sharper radar imagery and improved target separation.


This 18-inch, 4-kilowatt high definition radar has a 36 nm range, bringing radar images into even clearer focus. Combine that with the antenna’s 5.0 degree beamwidth, 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 when combined with a multi-function display and an optional heading sensor. MARPA tracking allows you to track the bearing, course, speed and predicted closest approach of up to 10 targets. In addition, like all Garmin radars, the GMR 18 HD has self-contained signal processing, which provides you with a more precise, easy to read signature.

Connect to the Garmin Marine Network

The GMR 18 HD 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.

GWS 10 Marine Wind Sensor

The GWS 10 wind sensor puts even more control in the hands of the sailor, allowing you to maximize the performance and speed of your boat with the use of wind vane technology.
Discover the Benefit of Harnessed Wind Power


Product Available: 4th Quarter, 2008
Part Number: 010-00737-00
Suggested Retail Price: $ 599.99 USD

The GWS 10 uses a wind vane for detection of wind direction and an anemometer to register wind speed.

Besides delivering wind measurements, the GWS 10 captures barometric pressure and air temperature data. When combined with other sensors, the GWS 10 provides those on board the ability to gather specific wind data such as ground and true wind, wind VMG and track heading.
Enjoy the Simple Interface & NMEA 2000 Connectivity

Combining wind and weather measurement from a single, integrated sensing unit, the GWS 10 installs with ease – providing data output to your cockpit display via NMEA 2000 cable and bus, which powers the unit. The GWS 10 is designed to interface with Garmin’s GMI 10 universal marine instrument, the 4000 and 5000 chartplotter series or any manufacturer’s NMEA 2000-enabled chartplotters and displays.
