Block GPS signals with this

If you’re paranoid of somebody tracking your every movement through a GPS bug planted somewhere in your vehicle, there is the Anti-Tracking GPS Blocker that will scramble and jam and signal broadcasting within the 1450 to 1600MHz range. All you need to do is plug it into the vehicle’s cigarette lighter socket and you’re good to go, as it encompasses you in a 4 metre “bubble” to prevent any GPS tracking device installed in your vehicle. While 4 metres works with virtually all cars, it falls short when it comes to lorries, trucks, trailers, and buses.
