Models with focus to cover tracking & locating devices. Black Box GPS trackers are virtualy everywhere nowdays, and there is no other way to render them unusable unless they are jammed by Jammers!

The Blackbox is this fancy gizmo that’s got not one, but two cores working their magic: GPS and GSM, like a dynamic duo!

But here’s the deal, if you wanna shut down both the GPS and GSM (GPRS) in that bad boy, you gotta get yourself a jammer that can tackle ’em both. ‘Cause if you only block the GPS with some regular GPS jammer, that sneaky Blackbox will slyly switch to the built-in SIM card for active GPRS GSM positioning.

Now, I know you might be wonderin’: “Hey, if I use a GSM blocker, will it mess up my cell phone signal too?”
No worries, my friend! The GSM blocker only messes with the GSM signal, so your 4G connection is safe and sound. You can still answer calls like a champ.
