The RAD 480i is the best performing radar detector in its class with 2x the detection range of its predecessor for advanced warnings plus next gen IVT filtering to eliminate unwanted alerts.
One of the best radar scanners in the market, it could be a little bit expensive but worth it, I've been using it for more than a year and it has saved from a few speeding tickets, it worth buying it.
Long Range Detection
Front and Rear Detection
You have to set the scanner correctly or it will detect false alarms including lasers from automatic doors.
