Mastiff™ cell phone detecting chair is a single piece, ruggedized chair that safely scans anyone sitting in it for contraband cell phones. The scanning is fast, accurate and sensitive enough to detect a mobile phone hidden in a pocket, sock or any body cavity. Mastiff's cell phone detecting technology allows security personnel to conduct intrusive and time-consuming personal body searches only when Mastiff detects contraband. Unlike most metal detectors that are either triggered by false positives or nothing at all, Mastiff is only looking for the #1 contraband problem in most federal, state and local prisons today - cell phones. Mastiff scans multiple zones simultaneously and provides a bright LED readout for each zone saving even more search time. The chair is lightweight (under 60 lbs.) and includes handles and built in rear wheels allowing any security detail to setup and transport the chair with ease. Internal DC battery or AC power allow Mastiff to run virtually anywhere. Stop your prison population from keistering, tucking, muling, and packing the rabbit / safe / trunk / suitcase with contraband cell phones. Mastiff is designed and manufactured in the U.S.A.
