I set one offf at a new super wal mart by carrying my $5, cuffs, two extra magazines, my wifes model 38 smith, and two speed strips, and a radio. And cerll phone. First two times, no one said boo. third day, I just told them i was packing, and showed the lady that marks your ticket. Probably not a good idea, but she said it did that a lot, she was sorry, they were still adjusting the thing.
As far as I know, the previous posters were right, those things work on radio frequency. How could this be?After the store was open a month, no more problems.Did my gun take a magnetic or radio frequency "charge'? Cell phone the culprit? The lady at the door seemed to indicate it was a common problem, and "they were working on it". beats me, and i am a ccw instructor.
