Calvana 4-Pack Magnetic Stud Finder Wall Scanner – No Batteries, Wall-Friendly Drywall Detector

Effortless stud detection for drywall projects

Meet the Calvana Magnetic Stud Finder, a practical tool designed to simplify mounting tasks on any drywall surface. By leveraging strong magnets, it identifies screw and nail head locations and clearly marks the exact spot on the wall. The best part is it requires no batteries or calibration, so you can rely on it anytime you start a project.

Built for comfort and wall safety, this tool sits easily in the hand with an ergonomic grip and a durable plastic body that minimizes surface marks. It works across a wide range of drywall constructions and can locate both wood and metal studs, making it a versatile companion for new builds, renovations, or upgrades. Note that it is not recommended for lath and plaster walls, where performance can vary.
