A stud finder is a device used to locate wooden studs behind walls, ceilings, or floors. Studs are vertical framing members that provide support for the structure and to which drywall, paneling, or other materials can be attached. Stud finders work by detecting the density of the material behind the surface being scanned. When the stud finder passes over a stud, the density of the material increases, which is detected by the device and indicated by a light, sound, or both.
Zircon is a brand name for a popular line of stud finders. Zircon stud finders are known for their accuracy, reliability, and ease of use. They are also relatively affordable, making them a good option for both homeowners and professionals.
