What is a Stud Finder?
A stud finder is a handheld electronic tool designed to help users locate the internal framing members, commonly called studs—behind walls, ceilings, or floors without causing damage to the surface. These devices have become indispensable in modern construction, renovation, home improvement, and even everyday household tasks such as hanging pictures, mounting TVs, or installing shelves. To truly understand what a stud tester is, it is necessary to explore its importance, how it works, its applications, and its role in both professional and DIY environments.
