Re: Metal detectors
The detectors do detect metal, if you watch when someone walks through it often lights up but not to a critical point and doesn't beep. My belt doesn't set it off as have walked through a couple times. However once had a t-shirt with 3 very small metal buttons, always set them off, guessing it was the type of metal used. Never wore it when flying!
Coins can too (UK ones at least). Even when i had a wad of notes in my pocket, not a random check.
But advice to travellers, don't be an idiot put it in the tray!! Nothing more annoying waiting to get through security when morons need patting down and we all have to wait for that to happen! Usually their bloody phones!
