Blue Sheepdog

Ask any martial artist and they will tell you: for every move, there is a counter-move.

In this case, the counter-move is a small device that jams GPS signals, preventing you from using them to track your suspect. It plugs into a cigarette lighter and emits a low power (200mW) jamming signal that claims to prevent tracking and logging using a GPS signal. The device specs indicate that it will jam GPS signals that are between 2 to 4 meters away.

I do not know of any testing that has been done to test these claims, but in theory, GPS signals are blockable. Pricing starts at $83.95. For more information, follow this link.

This has obvious implications for ongoing surveillance operations, and this device also raises concerns for officer safety.

Stay safe!
