Garmin GMR™ 434 xHD3 4kw 4' Open Array Radar and Pedestal Model: K10-00012-24 SCAN AVERAGING TECHNOLOGY IMPROVED TARGET-SIZE PROCESSING SPLIT-SCREEN DUAL-RANGE DISPLAY 100-KNOT COMMERCIAL GRADE WIND RATING 1 QUIET OPEN-ARRAY DRIVE MOTOR A first for Garmin magnetron radar, scan averaging helps filter out sea clutter and interference to enhance the detection and display of consistent targets. Pulse expansion and angular target-size processing techniques optimize on-screen object shapes for better interpretation at all range scales. The 100-knot wind-rated open-array antennas 1 have rotation speeds of 24 and 48 RPM for fast redraw rates, with max range up to 96 nautical miles on the 25-kW versions (up to 72 nautical miles on the 4- and 12-kW versions). A historical "trail" of boats on the water is displayed on the screen, removing relative motion influence to help you quickly identify moving targets and potential collision threats. A single radar antenna is capable of providing split-screen, side-by-side images on your compatible chartplotter, with independent range setting and controls for both close and long range. Overlay either or both ranges on a chart. Gain automatically adjusts levels to optimum settings for harbors, near shore and offshore in open waters. See overlaid images on your chartplotter's map screen (with appropriate sensors, sold separately). Pick out targets at a distance, thanks to narrow horizontal beamwidth and high antenna gain. Dual-radar support provides redundancy and allows each display unit to pull data from different sources. Radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions. Dynamic sea filter radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions. Locate flocks of birds at the
