Stud finders can detect any kind of density behind the thin layer of drywall. You can not only detect any wooden beam but also detect electric wires that are webbed behind the drywall.
If you want to hang any photo or set up any shelf to the wall, you surely don’t want to drill your drywall and cause a crack to it. You need a strong backing to hold up your thing. A backing of wood to drill out the screw. Therefore, you must detect the plank of wood behind your drywall.
In the past, people didn’t know how do stud finders work. So People used their knuckles to detect studs simply by hearing sounds. They even used magnets. Because the wooden structure of the house is joint together with screws. So, by finding metal screws leads one to find a stud. But it’s rather a slow process. But, where the power of the knuckle and the magnet ends, the magic of stud finder starts.
