NEW 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 optimise 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 influence 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 setting 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 harbours, near shore and offshore in open waters.
