Review on Advanced 6 in 1 Stud Finder with Digital Level – Enhanced Electronic Wall Scanner for Precision Detection, Sound Warning, Wood Locator, Digital Display, Beam & Joist Finders, Magnetic Stud Finder, and Edge Center Stud Finder by Nicholas Suave

I have used this mandrel finder on several projects and it gets worse with each use. In addition to the lack of directions, multiple walks along the wall will reveal posts that change position and posts with two right edges but no left edges. Reading cables is useless, which I've heard is common with many spike finders, but it's worth mentioning nonetheless. After a while I decided to use it mainly for finding metal plates in the wall, but then it started failing in that as well. On my most recent project, the finder kept reading that there were no metal plates in places where they would be obvious when drilling. He also started randomly reading a place with no metal plates as such. (Yes, I recalibrated.) Overall I'm very disappointed and now have a few gaps to fill.
