RYOBI introduces the Whole Stud Detector with Auto Depth Scan. This stud detector is a great addition for detecting whole studs and items behind your wall. The Multi LED's allow you to see the entire stud and not just an edge or centre. It uses Auto Depth Scan, technology designed to determine the thickness of your drywall so you can accurately assess what is behind it. With its material detection capabilities, you will always know when you are over metals (non-ferrous), and wood. With all these great features, the RYOBI Whole Detector is the best solution for all your detecting needs.
