The laser automatic 360-degree detection with ultra-fast scanning circuit provides additional detection range and the best early warning to obtain the fastest radar detection capability. Heterodyne technology with ultra-fast scanning circuit can provide a larger detection range and the best advance warning to obtain the fastest radar.2. The latest model radar of the radar detector (ultra-fast instant-on mode), which can detect any moving radial velocity monitor 800-1000m ahead.3. The relative speed sensing automatic mute system actually eliminates false warnings and shutdown functions, which will make your detector unable to be detected by currently available radar detectors.4. When you detect the location, the radar detector will tell you by emitting a sound to the speed detection device, so you can confirm your speed on the road. It has complete resistance to the VG-2 radar detector; even if the power is off, the settings of the radio detector can be electronically remembered indefinitely.
