Zircon StudSensor HD25 Stud Finder

Got this Zircon HD25 stud finder for sale. It's a pretty basic tool but it gets the job done when you need to find studs behind drywall for hanging pictures or shelves. It has the little red arrow and lights up when you hit a stud. Used it for a few projects around the house and it works fine, just dont need it anymore. Takes a 9v battery which isnt included. handy little thing to have in the drawer.
