You must have a metal object, a penny or key or belt in your pant's pocket. Otherwise you should have SSSS. I always empty out all my pockets, shirt or pant when entering that door. You just walk in straight and then collect your bag from the tray. Pre-check allows us to not have to remove belt but it will beep if you have belt right?
