I lost my stud finder. I read where you can detect nails using a magnet suspended from a piece of string. It does not work. It does detect the metal strips where the walls intersect. Is there another method?

If your smartphone has a compass and a mostly flat back, you can use a
stud finder app. They work well in my experience and are easy to use.

I installed 3 stud finder apps.

I am afraid that they are "useless at teats on a boar."
