If you have got tired of the first generation of portable cell phone jammers and want to be able to do some GPS jamming instead, this is your lucky day (and not so lucky for others).
Anti-Phone: Transmitting low power radio signals to cut off communications between cell towers and any cell phones in the proximity, this Cell Phone Jammer completely shuts down any GSM and DCS mobile phone signals within a 10 meter radius.
Anti-GPS: Worried someone has intentionally installed a GPS tracker somewhere in (or under) your car to track all your movements? It’s more likely than you think, but now worry no more because this jammer offers a perfect 10 meter radius of GPS jamming, ensuring your privacy no matter where you go or how large your vehicle is.
The Portable GPS and Cell Phone Jammer (GSM, DCS, GPS) is sold through the Chinavasion website with a retail price starting at about $36 USD.
