Can interfere with a wide range of frequencies, and can shield GPS signals

I bought this jammer a week ago. I chose it because it gives me a wide range of frequencies to jam, so I'll never need a shame again. It's powerful and portable, just stows whatever I want. In fact I needed a simple GSM scrambler but bought this jammer and now I use it for GPS jam and free wi-fi.
