Garmin GMR 18 xHD3 18" Radar Dome [010 02841 00] Prime Video: The Nanny, Season 2. GMR 18 xHD3 18" Radar Dome Loaded 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 Adjustment Pulse 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 Trails A 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 Overlay A 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 Gain Gain automatically adjusts levels to optimum settings for harbors, near shore, and offshore in open waters. Radar Overlay See overlaid images on your chartplotters map screen (with appropriate sensors, sold separately). High Resolution Radar Pick out targets at a distance thanks to a narrow horizontal beamwidth and high antenna gain. Dual Radar Support This provides redundancy and allows each display unit to pull data from different sources. Dynamic Sea Filter Radar gain automatically adjusts sea clutter for calm, medium, and rough sea conditions. Auto Bird Gain Locate flocks of birds at the waters surface, where baitfish are also likely to be found. MARPA Target Tracking Track up to 30 targets to help avoid collisions (with appropriate sensors, sold separately). Guard Zone Set the safety zone and receive an alarm when an object enters the zone. Range and Bearing Cues Variable range markers and electronic bearing lines allow rapid measurements of distance and bearing to vessels and land.
