Before I buy a frequency jammer, I want to know more. For example, what functions should a good jammer have? Hello! GrettaCary, your idea is very correct. We really need to understand the characteristics of things and the necessary knowledge, which is conducive to our purchase.

The story begins when European scientists discover a new source of energy, the nature of which is unknown. It is in a way connected to the portals located near the greatest monuments and memorials in the world. This energy comes from there, it controls the thoughts of everyone in the world, and it is forbidden to use mobile phone signal jammer in its area.

But these hijackers used GPS technology to steal more stuff. I will try to explain this possibility.

There are millions of cheap gps jammer devices in our modern cars. They include navigators and various security anti-theft devices with GPS tracking functions.
