GPS Jammer is an in-car spy sweeper

GPS Jammer plugs into your car's cigarette lighter port and blocks GPS signals.

No more road and track Chinavision

If your bulletproof raincoat , tape-recorder blocker , and surveillance detection device are just not enough to give you peace of mind, this in-car GPS jammer might be just what you're looking for. Once plugged in to your car's 12-volt cigarette lighter port, the device will apparently block all GPS signals in a broadcasting range of 1450 to 1600Mhz--translating into a a 2- to 4-meter radius of GPS anonymity, according to manufacturer Chinavision.

The GPS jammer might not be good enough to protect you from autonomous surveillance drones or spying robotic insects , but at least it will take them longer to find you.
