Standard electronic stud finders locate framing in applications that don't require sensing live wires. They signal with icons or flashing lights when studs are detected.

These electronic stud finders locate framing and also sense live wires to prevent accidental contact or damage when setting fasteners or cutting into walls. They indicate on their display when studs or energized wires are detected.

Magnetic stud finders contain an internal magnet that sticks to walls when it locates metal studs and metal fasteners on wood studs. They also have a built-in bubble vial for finding and marking level.
