This unique stud finder/nail starter can find hidden screws and nails in drywall or metal studs. Tis guaranteed permanent magnet will stay attracted to the wall so you don't have to mark the spot. Simply use the hole on the top of the device to start your hole. The Stud finder comes with a magnetic shield to prevent the magnet from attracting metal objects in your tool box. A convenient plumb line hang hole allows you to tie a string with a weight on the end to make your own plumb line.
