The SL72 Radar Kit includes an outstandingly clear, high contrast 7'' LCD display and streamlined antenna, plus easy to use controls for instant access to all commonly used functions. The viewing angle and contrast are the best available. A narrow horizontal beam width (5.2?) is 20% more concentrated than most other LCD Radars, so you get better resolution and improved weak target detection. A low noise converter provides enhanced target detection and improved performance levels. Minimum range of 1/8 mile and maximum range of 24 miles. The unique AUTO GST makes the SL72 the first truly automatic radar, programmed to sense its surroundings and adapt to them by automatically adjusting Gain, sea-clutter and tune for optimal picture quality. Off Center and Zoom functions. When connected to NMEA or SeaTalk GPS or Loran, the Pathfinder will display waypoint data and nav data in unique data boxes on the screen. Waterproof Display. Includes 2 EBL's, 2 VRM's, 4 levels of grey scale display, guard zone and 9 range scales. 8.66'' x 5.6'' x 4.4'' display.
