Portable GPS & Cellphone Jamming Detector

Handheld Anti-Jamming Detector is designed to detect and locate if any GPS jammer or cell phone jammer around the vehicle.

GPS Signal blocker is working by transmitting the same GPS L1 frequency, overwhelming the signal, so GPS tracker cannot report the correct position. Jammers prevent stolen vehicles being tracked, also some drivers may use jamming to try to prevent detection by police and avoid fines; criminals use GPS blockers as cover for vehicle theft or illegal activity or driver to prevent the employer from knowing where they are going with the company vehicle.

Anti GPS Jammer protects GPS receiver from blocking navigation and interference. The handheld GPS Jammer Detector can pinpoint where jamming sources and located jammer.
