This center detect Stud Finder has a detection depth of 1-1/2 inches for wood and metal. Traditional stud finders locate the edge of the stud, but this product locates the center for a more efficient read, even when held at an angle. Plus, it is constantly calibrating to save time during use. An audible alert and directional LED arrows clearly notify you once the stud is located, and you can easily mark the center of the stud with the center marking channel.
