Very intuitive and precise tracking of the stud and its center

If you need to find stud inside the wall, this is your gadget. It precisely positions it by a set of 15 LEDs and as you move the device it shows exactly where the stud is. There is a sticker that marks the center of the stud by green color. Outstanding.

Best stud finder

Out of all stud finders this one is the best it's precise on the middle of the stud and finding if there is live wires. I would recommend this to anyone that this is where you should spend your money on if you need a good stud finder
