I thought the device they found in Lesli's lab was a metal detector and it picked up the chips that Charles planted in the back of their necks. Depending on the type of research Lesli and her fellow researchers are working on, a metal detector could be needed. It looked like the same kind of device that they use at airports if you set off the larger metal detector.
