Coincidentally, we have recently developed a waterproof jammer to prevent underwater pollution. Our powerful jammer can meet your requirements, is easy to install, and has a waterproof function, you can install and use it anytime, anywhere. This waterproof mobile phone signal handheld jammer can effectively block Bluetooth 3G 4G WIFI GSM mobile phone signals. Mobile phone jammers prevent mobile devices from receiving signals from the base station by sending the same frequency. The compact size of the interference output is 40W. It will effectively block all designated signals within a radius of 40 meters. And its use is very simple, without too complicated installation steps.
