Use Your Device to Detect Studs and Magnetic Fields. Quickly detect wood studs hidden under walls, drywall, plasterboard, or stucco. Wall Stud Magnetic Detector uses your device's compass (magnetometer) sensor to precisely pinpoint metal studs, nails, screws, and other metal fasteners embedded in all wooden wall studs. This app operates in a similar manner to other hand-held stud detector tools: as you move the device along the wall, the needle will move and a beep can be heard. The compass sensor detects subtle changes in the background magnetic fields caused by the conductive metal fasteners that are located in all wooden studs. Features: - Automatic sensor that measures the magnetic field in uT. - Active detection beep. - You can store the time when the stud is detected. There is also a quick video tutorial that shows how the app works: https://www.youtube.com/embed/gTQHwS7XwXk?rel=0 Happy construction. Download now!
