Cobra SPX-5500 Radar/Laser Detector (Refurbished)
Fast-sweep circuitry constantly scans your surroundings for radar and laser, giving you a heads-up when a speed trap or radar gun-toting trooper is up the road. The scanning system is compatible with most radar and laser systems used in the U.S. and Canada, keeping you safe no matter where your travels take you.
POP radar guns, which send speed detection pulses in tiny millisecond-long bursts, are designed specifically to defeat radar detectors. The SPX, series, though, boasts a dedicated POP mode, which alerts you to even the fastest instant-on speed detectors.
Detection: Radar signals (X, K, Ka and Ku bands, with signal strength indicated), Safety Alert signals, Spectre I & IV+ signals, VG-2 signals, LTI 20-20, LTI Laser, Kustom Signals Laser 340, Kustom Signals Laser, Stalker LIDAR, Laser Atlanta SpeedLaser/Kustom Signals-ProLaser II
I don't know if this works or not but it doesn't go off at all when I'm driving past police. I keep my old radar detector plugged up in my car at the same time and it alerts me when police are near as the Spx -5500 did NOTHING I WANT A REFUND
Doesn't work well at all! Says there is a train approaching every minute with no train in sight. Also says emergency vehicles is approaching all the time with no emergency vehicle in sight as well. Drove through a speed trap and it didn't go off or read it at all. All around bad product! Very disappointed
