well............Security detectors, anyways. Got the application from the Garrett rep, as I engineer fire and security systems for schools and medical buildings. Since the VT killings, we have received many requests for lockdown abilities and areas of security concerns in auditoriums. After I was sanctioned to find manufacturers of expanded security concerns, I quickly chose Garrett for the walkthrough metal detectors. Now I have to see if they will sneak me some hobby equipment at the security discount. Hehehe.
