Be alerted to radars around your vehicle with the Whistler XTR-658 Laser Radar Detector with Total Band Protection & Voice Alerts. Using a high gain optical lens, the radar detector provides increased sensitivity and field of view for leading-edge laser detection. The radar detector provides total band protection from X band, K band, SuperWideBand, and Ka Laser, and includes a built-in POP detection mode, which responds to brief bursts of radar. The detector features a blue OLED text display which shows alerts detected, engaged modes, and digital signal strength, and operates using your car's built-in 12V socket and the included power cable so you never have to worry about charging or replacing batteries.
