RE:Perhaps an expert among u guys My guess is that the faraday cage itself would show up on the patscan. My understanding is that the patscan will not only recognize weapons from its database, but it will also alert for suspicious items. In the end, any system can be defeated. Again, PAT is not designed to be used in isolation. You have an interesting profile (no criticism intended) but your account is well over a year old and that was your one and only post ever. Welcome!
