The laser automatic 360-degree detection with ultra-fast scanning circuit provides enhanced detection range and early warning for improved radar detection performance. Heterodyne technology with ultra-fast scanning circuit delivers extended detection range and advanced warning capability. The latest radar detector model features ultra-fast instant-on mode, capable of detecting moving radial velocity monitors up to 800-1000 meters ahead. The relative speed sensing automatic mute system helps reduce false alerts and includes shutdown functions to minimize interference. The device offers protection against current radar detection systems. When a speed monitoring location is detected, the radar detector emits an audible alert, allowing you to verify your speed. It provides full immunity to VG-2 radar detector detection. Settings are retained electronically even when power is off.
