I've begun using the MMW systems equipped with the ATR/gumby software since there's really no health risks from low energy RF and no more virtual strip search being conducted by a voyeur in a viewing room. (Forget x-ray/backscatter tho, ATR or not). I'm sure you've all heard the barkers yelling about "all belts off, nothing in your pockets, not even your ticket, or chapstick, or lint", yada yada yada. Well, I was so focused on ensuring that all my pockets had absolutely nothing I forgot to remove my leather belt with a large metal buckle. It was under my pullover sweater so wasn't visible to the guy that ordered me into the machine.

The result after getting scanned? Absolutely nothing. Green screen, good to go. It seems the machine could care less that I went through with a belt. I know that particular belt couldn't pass the WTMD (I'd tried it before) but MMW was fine with it. I'm starting to think that all this yelling that a piece of paper will cause the machine to alarm is BS. I'll make sure to wear the belt through MMW in the future unless a screener notices and browbeats me into removing it. If it alarms in the future I'll update this thread.
