GMR!22 18 HD Radome

Model: GMR!22 18 HD Radome Brand: Garmin

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" (45.7 cm), 4 kW high definition radar has a 36 nm 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 antennaâ AC!22s 5 degree beamwidth, and youâ AC!22re 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 boatâ AC!22s 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.
