I wasn't expecting an electrical wire so high in the wall, but this scanner picked it up.

Would Not RecommendIf the studs actually looked like an anaconda that swallowed a bunch of odd shaped objects I would have been impressed.

magnet works better

Stud finder
Would RecommendNeeded an instrument to find studs behind drywall in bedroom for hanging shelves. Didn't want to spend a lot for a mega-function finder. Found this one in the tool section. Reasonably priced. Had the functions I needed. Worked great! Got me the results I wanted.
