Garmin GMR 18 xHD3 18″ Radar Dome [010-02841-00]

GMR 18 xHD3 18″ Radar DomeLoaded with advanced features typically found on open arrays, this powerful 18″ dome radar offers superior traffic, obstacle, and weather detection for peace of mind on the water.Features:
4 KW power output, 48 nautical mile max range
Scan-averaging technology
Improved target-size processing
Split-screen dual-range display
Bird detection
Quiet dome-drive motor
Scan Averaging Technology A first for Garmin magnetron radar, scan averaging helps filter out sea clutter and interference to enhance the detection and display of consistent targets.Angular Target-Size AdjustmentPulse expansion and angular target-size processing techniques optimize on-screen object shapes for better interpretation at all range scales.Faster Scanning Antenna Rotation speeds up to 60 rpm improve the redraw rate for faster target updates.True Echo TrailsA historical “trail” of boats on the water is displayed on the screen, removing relative motion influences to help you quickly identify moving targets and potential collision threats.Dual Range with OverlayA single radar antenna is capable of providing split-screen, side-by-side images on your compatible chartplotter, with independent range settings and controls for both close and long range. Overlay either or both ranges on a chart.Dynamic Auto GainGain automatically adjusts levels to optimum settings for harbors, near shore, and offshore in open waters.Radar OverlaySee overlaid images on your chartplotter’s map screen (with appropriate sensors, sold separately).High-Resolution RadarPick out targets at a distance thanks to a narrow horizontal beamwidth and high antenna gain.Dual-Radar SupportThis provides redundancy and allows each display unit to pull data from different sources.Dynamic Sea FilterRadar gain automatically adjusts sea clutter for calm, medium, and rough sea conditions.Auto Bird GainLocate flocks of birds at the water’s surface, where baitfish are also likely to be found.MARPA Target TrackingTrack up to 30 targets to help avoid collisions (with appropriate sensors, sold separately).Guard ZoneSet the safety zone and receive an alarm when an object enters the zone.Range and Bearing CuesVariable range markers and electronic bearing lines allow rapid measurements of distance and bearing to vessels and land.In the Box:
