Feature details

• 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 chartplotter’s 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 water’s 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).
