If you’re a contractor, electrician or construction worker, you know how important it is to locate studs in walls. Rather than banging on the wall and listening for a change in the way the hammer sounds, a stud finder or stud sensor is so much faster and certainly more accurate.
Magnetic stud finders are great in commercial buildings where metal studs are used, but they’re not always accurate since they will also identify metal pipes and conduits. The electronic stud finder uses technology that detects the change in the wall density. When a stud is identified, the unit lights up indicating a stud has been found.
