What Is the Purpose of a Stud Finder?

A house is usually constructed around a wooden frame. This wooden frame makes it easy to build a house. These frames have vertically lined wooden boards called studs. These studs are what holds the drywall. A stud finder finds the studs behind these walls that you would not be able to locate. There are many stud finders in the market right now, but they are primarily categorized between magnetic and electrical stud finders.

Magnetic stud finders are more like manual stud finders that find studs using magnets. These stud finders are more user dependant and require the user to move around with the stud finder pressed against the wall. The movement of the magnet determines the location of the stud behind the wall. The reason behind it is that studs are often bound and joined together using fasteners and nails. The magnet finds the nails and metal fasteners behind the walls to locate studs.

On the other hand, electrical stud finders use sensors. These sensors can not only locate studs behind the wall but also AC wires so you don’t end up hammering a nail into one accidentally. Stanley FatMax Stud Sensor 300 is also an electrical stud finder with multiple sensors. It can locate pipes, studs, and AC wires behind walls. It can also locate railing in concrete walls so you can avoid drilling into them.
