Wide detection range - Detects the latest POP mode radar gun (super-fast instant on mode). This radar detector can identify any stable or mobile radial speed monitor from 250 to 2500 meters ahead. Extreme Range Superheterodyne technology with super-fast sweep circuitry provides extended detection range and advanced warning for fast-acting radar guns. Detects Ku Band radar signals currently used in Europe. When a signal is detected, the GPS alerts you with an audible tone to indicate proximity to a speed monitoring device, allowing you to verify your speed on the road. Offers protection against radar detector-detectors. Electronically retains settings indefinitely, even when powered off. Features a relative speed sensing auto mute system that minimizes false alerts. Shutdown function helps render the detector undetectable by current radar detector-detection technologies. Includes 360-degree laser detection capability and is easy to install.
