This nail finder works well, I've used it on plastered walls that had a half inch of drywall on top. Found all studs with absolute precision. It can be finicky, but all you have to do is reset it. I had a zirconia finder and it works just as well if not better. The only thing I don't like is that the power button is at the top. I kept it in the original packaging with my tool (household electrician) but sometimes in transport it shifts and turns on the spike finder.
