The Bosch Professional Wall Scanner and Stud Finder is currently the one we recommend for most people—and it has been for several years. That’s because of its reliable and clear detecting of most things that could be hidden inside your walls. In addition to finding wood studs, the Bosch located live wires, metal studs, and copper and iron pipes during our testing.
