The Stud sensor E50 quickly and easily locates the edges of wood and metal studs and joists behind walls, floors and ceilings. Its easy-to-read display screen indicates stud edges, the patented spotlite pointer shines a beam of light on the wall to identify the target and wire warning detection indicates the presence of live AC voltage. Its new patent-pending pinch grip and contoured shape provide an easy, secure hold in either hand, at any angle.
