I find a strange tool and offer a prize to the winner.

My elbow is also quite sore today and I bet my saw is now out of square…

Magnetic stud finder. Slide the plastic along the wall and the magnetic piece in the middle will find the drywall screw heads.

JayT is right. Magnetic stud finder. The magnetic tip is designed to locate drywall screws, or nail heads back in the day. The red tip tracks the direction of the metal in the wall when you pass the locator over it so you can find the exact location for the nail.

Of course, the accuracy of finding the stud is only as accurate as the drywall contractor in locating the nail/screw in the center of the stud. But, it gets the job done.

It’s funny, someone got this right off the bat, so clearly the were common.

I’m 36 and I’ve never seen one. (obviously) I tried to use it this morning. It works, but with a fair amount of finesse. I can see why I’ve never see them, I’m betting they were pitched pretty readily for the electronic density versions!

You can still find magnetic stud finders at most hardware stores in various configurations. They do have drawbacks compared to the electronic versions, but they also don’t break and never need batteries. I keep a small one from CH Hanson in my remodel toolbox, as well as an electronic one.

Doing a lot of work in office buildings, remodeling most office buildings use steel studs for the walls to locate them we used what is called a cow magnet it’s a strong magnet about 1 1/2” or 2” long maybe 1/2” to 3/4” cylinder with rounded ends we attached a rubber end of a eye dropper to a sting than stretched it over the end of the cow magnet. when looking for the hidden studs you just dangle the magnet and slid it across the wall when you came to a steel stud the cow magnet would stop and the center of the magnet cylinder was the center of the stud.


What are they?

Cow magnets are popular with dairy farmers and veterinarians to help prevent Hardware Disease in their cattle. While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron). Tramp iron tends to lodge in the honeycombed walls of the recticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as Hardware Disease. The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and recticulum. One magnet works for the life of the cow
