A GPS Blocker for Specifically Tracking MPH
I use this to block GPS tracking (specifically tracking MPH of company vehicle). It works great (up and beyond description) as far as distance. It blocks my personal GPS from over 50 ft away. Just nulls multiple satellite retrieval that pin point your location. It is easy to use (there is only an on/off switch). Charge lasts easily 10 to 12 hours, if not longer. I use to block L1 systems. I bought it taking a chance that the system I was trying to block was L1 and IT WAS!
Once I turned it on, it blocks your current location/speed/etc… But will it will still show your last location when you turned on the item. It is not a problem in my case, but I guess it could be problem for others some times. .
Actually when you are using this item, you will some problem here, If the GPS to be jammed is on the same vehicle as the jammer, it will not work appropriate, you can be assured. GPS blocker in vehicles sitting next to you will likely experience loss of signal, this little beauty really brings the heat! As others have stated the antenna seems very stiff and it could be an issue, but if you are knowing this is careful and treat it like an electronic device and not a hammer and you should be fine. So I think if you find an appropriate way to treat such kind of issue, then you will find this item is a good for you. And you also can find that the car gadgets work great.
May be you will find there are many better articles than this, but please note relationship quality price gets an approved high. I think if what you want to run is not a crawler vehicle or a GPS you have less than 15 meters, this block GPS is your article.
