Features 1. The radar detection technology can detect the signals before and after the vehicle, and the effective speed point distance of the front and back scanning is 300-600 meters. When scanning at any angle, the speed measurement has no blind spots. Our detector combines excellent radar and laser performance, no matter where you go for adventure, it can give you all-round protection. 2. Unique voice prompt, humanized real-time voice warning in English and Russian, which can realize hands-free operation and clear communication. The radar detector will issue an alert based on your customized speed to detect in advance any traffic monitors or stable cameras(Around traffic lights) near your current location. When the radar recognizes a location, it will send out a sound signal to inform you that you are approaching the speed detection device. This way you can be aware of threats before they appear. 3. The radar detector has ultra-high sensitivity and can be adjusted in five bands. Automotive radar detectors can detect radars from 300 to 600 meters nearby. The highest sensitivity can provide radar warnings hundreds of meters away, providing a larger detection range, and even the fastest radar cannon can provide the best to the driver. 4. City mode/highway mode are available for selection, which can reduce false frequency fields in densely populated cities. Long-range radar detection has super-distance super-heterodyne technology and super-fast scanning circuit, which can help you expand the detection range and accuracy. Provide you with continuous protection during driving and avoid unnecessary speeding traffic fines.
