The Best Cheap Stud Finders of 2019
If you want to hang something heavy on a wall (like a television, mirror or bookshelf), you want to secure it to a stud.
Studs are beam-like pieces of wood (or metal) that run vertically inside a wall, spaced 16 or 24 inches apart on center. You can't see studs within drywall or plaster, but a stud finder can sense them.
Many stud finders are handheld and battery operated: They beep or flash when they find a dense part of the wall. Some models can detect false positives (like water pipes) or live wires (to help prevent electrical shocks). The simplest stud finders are just powerful magnets that are attracted to nails in the stud.
Stud finders are convenient, but they aren't necessary. Experienced handymen and contractors can find a stud by tapping their knuckles on a wall and listening for a change in sound. Nevertheless, a stud finder is worth it for anyone who wants to save time or double-check his or her guesswork.
