Wide Detection Range - Detects the latest popular mode radar gun (ultra-fast instant start mode) This radar can detect any stable or moving radial velocity monitor 250-2500m ahead. Extreme Range Superheterodyne Technology - Technology with ultra-fast scanning circuitry that provides additional detection range and optimal early warning detection for even the fastest radar guns Extreme Range Superheterodyne Ku-band radar guns currently in use in Europe technology, using ultra-fast scanning circuitry, provides extra detection range and optimal early warning of targets even with the fastest radar guns. When you detect a location, the GPS will tell you by making a sound that you are approaching a speed detection device so you can confirm your speed on that stretch of road. Provides complete immunity to VG-2 radar detector detectors; electronically remembers radar detector settings indefinitely, even if power is lost. The relative speed sensing automatic mute system virtually eliminates false alarms, and the shut-off feature will render your detector undetectable by currently available radar detectors. This radar detector features a laser eye detector for 360 degree laser detection and is easy to install. About: All items will be shipped within 3 business days after payment is received.
