“The Zircon Metalliscanner M40 Metal Locator tool is a better way to find studs over other devices I've used. When I received the unit found it to be a good size to hold in your hand.

“I've had very poor luck with electronic stud finders on my 1950s walls, which I believe are plaster board. The StudPoP promised to work with them, and I'm happy to report, it delivers! It quickly and consistently found studs at the proper spacing that I had previously spent an hour trying to locate ... that the electronic ones couldn't find at all.” — Gonzo · homedepot.com
