Detailed Product Description

The answer to all GPS GSM & UMTS or 3G telephone / tracking devices. 
Because GSM jammers will only prevent GPS / GSM tracking devices to communicate with the base station, there is also a UMTS or 3G jammer available, all in one device! 
The GPS / GSM devices are still able to receive and buffer all GPS positions. The tracking devices will still be able to send out all the GPS positions if the car or when the GSM jammer is shut down. So they can still see where you went that day. 
Only GPS jammers will prevent the GPS loggers and GPS / GSM devices to get GPS positions from the Satellites. But they still can track you by the GSM network used by the GPS / GSM devices or track you by your mobile phone. 
So the best solution against all modern tracking devices is the GPS / GSM / UMTS or 3G jammer. It can be easily being placed in your car, home or office and works on the 12 V sigaret lighter.
