When you spend vacation with your family, when you go to a business trip, you have no idea that maybe you have been spied by a GPS device. GPS devie helps us a lot in navigation, but it is also dangerous that it may expose our location to bad guys. To solve this, we need GPS jammer, which can block the GPS signal in a certain working range.

For example, the GPS jammer model S808033 is a good one. It is a New Cellphone Style 10 Meters Mini Portable Cellphone / GPS Signal Jammer. With a very small size, it can be taken with you at anywhere anytime. Not only shields the signals from mobile phone but also blocks any signals from GPS tracking gadgets. Besides, it does not affect the normal operation of other electronic devices. Inside the machine, slow start-up circuit can avoid sparkling caused by mechanical switch. Light weight,the jammer is very easy to carry and use. It has built-in battery, which makes it a really portable one. Jamming Range: Radius 1- 10 m (the Cellular signal must≤-85dBm in the location),the jamming radius still depends on the strength signal in given area.
