This is super easy to use. You hold it and press against the wall and it will light up green when you find a stud. It's very accurate. It requires batteries and it lasts a long time.

The HART Basic Stud Finder is a handy tool that delivers reliable accuracy for quick and confident stud location. Its versatility makes it useful for various wall types, and the sturdy build adds durability. Lightweight and easy to carry, its portability is a plus, and the battery life lasts through multiple projects without fuss.

I ❤️ this stud finder. It's always on point with the studs an even tell you if there are electric wires in the stud as well. 👍🏼 I haven't had to change battery in 2 years. An very portable always in my tool bag.
