Speeding Alarm System 360-degree Automatic Vehicle Detection. Vehicle Speed Prompt Detector Laser automatic 360 degree detection with ultra-fast scanning circuit, event fastest radar gun provides additional detection range and best early warning detection Ku-band radar gun currently uses extreme range superheterodyne technology in Europe, with ultra-fast scanning circuit, event fastest radar gun provides additional detection range and best early warning. [Wide detection range]-Radar detector latest popular mode radar gun (ultra-fast instant on mode) This radar can detect any stable or moving speed speed monitor 250-2500 meters ahead. Advanced system - relative speed sensing automatic mute system, virtual elimination of false alarm sand shutdown function, will make your detector unable to detect through the currently available radar detector-detector. [Quick Response]-When you detect a location, the lidar detector tells you byittingasound that you are approaching the speed detection device, so you can confirm your speed. A fully immune radar detector setting that provides a VG-2 radar detector-detector can be remembered electronically indefinitely, even in the event of a power outage.
