Furuno&#x27;s NXT radars are Solid-State Radars utilizing Doppler technology to ensure the safest navigation. The NXT series features Target Analyzer™, Fast Target Tracking™ and Auto Target Acquire function to offer optimal detection and sensitivity of hazardous objects. Combined with RezBoost™ technology, the NXT Radars have no equal in spotting and tracking targets moving around your vessel. The DRS6A-NXT is a Solid-State Radar with pulse compression and Doppler frequency shift sensing technology, built into your choice of a 3.5ft, 4ft, or 6ft open array. This &quot;NXT&quot; (read &quot;next&quot;) generation Radar is designed for use with both NavNet TZtouch and TZtouch2 MFDs. The DRS6A-NXT is packed with new features, but perhaps the most innovative and revolutionary is called &quot;Target Analyzer&quot;, facilitated by Furuno&#x27;s Doppler technology. The Doppler &quot;Target Analyzer&quot; will automatically change the color of targets approaching your boat to clearly show any hazards. Green echoes are stationary targets, land, or approaching targets moving at a velocity of less than 3 knots. Echoes dynamically turn red when targets are approaching your vessel at a speed of 3 knots or faster. It works the same when you are following another vessel. If the target is getting closer at a speed of 3 knots or more, the echo will be depicted in red on the screen. Incredibly, &quot;Target Analyzer&quot; works independently of one&#x27;s own ship speed!
