Whistler DE1783 All Band Laser-Radar Detector - Performance Certified by Speed Measurement Labs Inc. Improved Performance with POP Mode Detection Capability ALL BAND Laser Radar Detector with POP Mode, Digital Compass Headings, Real Voice, and High Visibility Text Display. Features: POP Mode Detection Capability – POP mode is a feature on some newer radar guns operating on K or Ka bands. When the gun is in POP Mode and activated, a brief burst of energy, less than 1/10th of a second, is transmitted and the vehicle’s speed is quickly acquired. A detector without POP Mode detection capability cannot respond to this brief transmission. This detector has the power to report this new gun where others detectors cannot!
