[Ultra-Long Range Superheterodyne Technology] Automatic 360-degree detection has an ultra-fast scanning circuit, providing an ultra-fast radar gun for events currently using ultra-long-range superheterodyne technology in Europe. The Ku-band radar gun has an ultra-fast scanning circuit, providing Over detection range and optimal event warning. [Advanced System] Relative speed? ? The sensor auto-mute system virtually eliminates false alarms, which will prevent your detector from being detected by currently available radar detectors. [Wide Detection Range] The most popular mode of radar detector is radar gun (ultra-fast real-time mode). This radar can detect any stable or moving speed monitor 250-2500 meters ahead? fast reaction? When you detect a location, the radar detector will tell you by making a sound that you are approaching the speed detection device, so you can confirm that your speed is on track. Fully Immune VG-2 Radar Detector - Detector; radar detector settings are remembered electronically indefinitely, even in the event of a power outage.
