The GMR^TM 18HD Radome uses digital processing technology and the mariner can adjust the gain, wave, rain and snow settings based on different weather conditions to obtain clear and sharp radar images. The HD disc radar can generate 4 kW of transmit power with a maximum range of 36 nautical miles, support MARPA function and track 10 targets at the same time. The GMR^TM 18HD Radome is simple to install, easy to operate, and compatible. It can be used with a variety of matching chart machines to achieve all-weather monitoring of the surrounding environment of the vessel and provides satisfactory radar images.

The GMR 18 HD radar offers a whole new level of radar scanning capability and make clearer radar images through digital processing techniques.

? Get Powerful Performance

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

This 18" (45.7 cm), 4 kW high definition radar has a 36nm range, bringing radar images into even clearer focus. With automatic pulse optimization technology, the radar matches pulse widths and repetition rates with the nautical mile range that is selected. Combine that with the antenna’s 5 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 MB 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 also can split the on-screen display so you can view the map and the standard radar page simultaneously.
