Mini Pocket Vehicle Anti-Tracking GPS Signal Jammer , GPS Blocker
The GPS jammer is a small and light device which can be easily to carry and use.
We designed this small yet very handy device in order to help millions of truck drivers around the world who suffer from GPS tracking placed in their 18-wheelers by their employers and who think that their privacy rights are violated in this way.
This GPS jammer can only block GPS signal, and CANNOT block GSM/GPRS signal which is usually used by some GPS trackers!
It can be used directly as long as you insert it into the cigarette lighter/12V auxilary device within the car.
