This is without a doubt the best stuff finder I have ever used. It was easy and found every stud in the wall in seconds. So much better than any of the other fancy ones! Buy this one and relax. Nick · homedepot.com

Like any scanner, this will not tell you if it sees a pipe or a stud. The scanner has no way of knowing. It will however tell you if a live wire is present. One thing is for certain, when it says something is there, it's there. This is worth the money for sure, because it is dead accurate and can find the center of an object every time. This is also the deepest reaching scanner I have ever used. H Guest · zoro.com
