Wide detection range - Detects the latest POP mode radar guns (super-fast instant on mode). This radar detector can detect any stable or mobile radar 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 radar guns. Detects Ku Band radar guns currently used in Europe. When a detection occurs, the GPS alerts you with an audible signal indicating proximity to a speed detection device, allowing you to verify your speed on that stretch of road. Offers immunity to VG-2 radar detector-detectors. Electronically retains radar detector settings indefinitely, even when powered off. Features a relative speed sensing auto mute system that reduces false alerts. Shutdown feature helps make the detector undetectable by current radar detector-detector technology. This radar detector includes a 360-degree laser detection sensor and is easy to install.
