The Garmin GMR 18 xHD Radar is a hi-definition radar dome. 18-inch in size, this high-definition radar dome pairs ease of use with advanced features typically found on open arrays for enhanced situational awareness.

This 18-inch radar dome is easy to use and has options to make installation simple. It packs the power and echo definition you need, at all ranges. When weather and sea conditions shift, the gain and sea filter do too automatically. See what’s close and far away with dual-range operation.
