1. The laser automatic 360-degree detection with ultra-fast scanning circuit provides extended detection range and advanced warning for fast radar detection. Heterodyne technology with ultra-fast scanning circuit offers improved range and early detection capabilities. 2. The latest model radar detector features an ultra-fast instant-on mode capable of detecting moving radial velocity monitors up to 800-1000 meters ahead. 3. The relative speed sensing automatic mute system helps reduce false alerts and includes shutdown functions to minimize interference. 4. Upon detection, the radar detector emits an audible alert to notify the user of speed monitoring devices, allowing confirmation of vehicle speed. The device offers protection against VG-2 detection; settings are retained electronically even when powered off.
