Hi, what product did you get from Amazon? I have a filming project documenting the Apron expansion at an international airport. It would be good to know which products work for blocking the gps signal.Got my cell blocker pouch today from Amazon, took it apart and took the cloth part that blocks the gps signal it works great. I think much better than tin foil. 0 satellites with it over the top. Took it off got full gps signal put it back on and immediately went to 0 satellites.
Do you have a link?
Many thanks
Richard
