Understand though, taking your shoes off is in YOUR best interest. For whatever reason, each machine seems to vary in sensitivity - just because your shoes didn't beep at DFW, they may at ATL. You only get one shot to go through the machine; if you go through the machine and you beep, you cannot go through it again (gone are the days when you just keep walking through again and again).

Once you beep, your pulled aside and you can add another 10 minutes to your wait. Therefore, it is to your best interest to take shoes off, coat off, change out of pockets; everything you can do to assure that you do not beep when going through the machine.
