Reviews: 5 Band Portable GPS Signal Jammer + Cellular Phone Signal Blocker

recommend rating

That's really awesome device! I could never even think about using some kind of jamming technology and I've thought that I’ll never really need one. But my boss installed a Geotab fleet management system somewhere in my truck, so that signal jammer became pretty handy, it jams not only GPS, but Geotab's GPRS Internet connection. Now nobody can track me if I don't want it!
