This high-definition open-array radar is perfect for cruising and fishing offshore, overnight and in foggy, limited or no-visibility conditions especially on yachts and sport fishing boats under 40 Feet. Increase the duration of the transmit pulse, which helps maximize the energy on targets. This provides larger target size on the chartplotter. Locate flocks of birds at the water?s surface where baitfish are also likely to be found. A historical ?trail? is left on the screen to help you quickly and easily identify moving targets and potential collision threats. Single radar antenna is capable of providing split-screen images on your chartplotter for both close and long range. Using dual radar provides redundancy and allows each display unit on the boat to pull data from one of two different radar sources. Gain automatically adjusts levels to optimum settings for harbors, near shore and offshore in open waters. Gain automatically adjusts sea clutter for calm, medium and rough sea conditions. Overlay radar images onto your chartplotter?s map page. You can add an optional autopilot or heading sensor for best results. Mini-automatic radar plotting aid tracks up to 30 selected targets, helping you keep track of other vessels and avoid collisions. Set the safety zone, and receive an alarm when an object enters the zone. Single radar antenna is capable of providing split-screen images on your chartplotter side by side, with independent range setting and controls for both close and long range. One or both ranges can also be viewed as a chart overlay.
