I kept setting off all the detectors at both the parking garage checkpoint and all the roller coasters. It was a standard belt, a metal clasp more than a buckle, so the sensitivity on the machines is pretty high. I just lifted my t-shirt and let them wand me. Never had to remove the belt. Only had one guard think I was trying to deflect attention by having them zero in on the belt, but I think that is good for him. He was paying attention and playing out the situational possibilities.
