A funny fact about stud finders is that they are often featured on TV and movies as if they are magical devices that can find anything behind walls. In reality, these devices are mostly used to locate the metal studs and joists that make up the frame structure behind the wall. On the hit show Friends, Rachel used a stud finder to try and locate a hidden stash of money which the device obviously could not detect. It's a humorous reminder of how stud finders are often seen in popular culture. Source
