Magnetic Stud Finder 160
The Johnson Level & Tool 160 is a magnetic stud finder designed for DIYers and tradespeople who need to locate ferrous metal fasteners behind walls. It operates without batteries and uses a simple magnetic pull to indicate the position of nails or screws in wood or metal studs. The reflective backing on the vial improves visibility in low-light conditions. It suits anyone who prefers a tool that is always ready to use.
Detection limits and practical use
The device detects ferrous metal up to a maximum depth of 1/2 inch and provides an accuracy of 2 mm/m. It does not detect wood, non-ferrous metals or live electrical wiring, so it cannot locate stud edges or pipes directly. Users must rely on finding the metal fasteners that attach wallboard to the framing. The tool gives no audible or visual signal beyond the magnetic attraction itself.
Upgrade considerations
This finder replaces the guesswork of tapping walls or using a small handheld magnet. It is worth choosing when you want a dedicated, battery-free tool with a built-in vial for leveling and a reflective surface for better readability. It is not for buyers who need to detect wooden studs without metal fasteners, locate plastic pipes or identify live cables behind drywall.

Questions about this item
How does the Johnson Level & Tool 160 differ from electronic stud finders with multiple scan modes?
The 160 uses a permanent magnet to locate ferrous metal fasteners up to 1/2 inch deep, requires no batteries, and has no electronic scanning modes for wood or live wires.
What does the 2 mm/m accuracy figure mean when I am marking stud centres on a wall?
It indicates the vial level tolerance, so the tool helps you keep a straight horizontal line while you slide it to find the nail or screw heads behind the surface.
Since the finder relies on a magnet, what limits its detection depth in practice?
It only responds to ferrous metal such as nails or screws, with a maximum reach of 1/2 inch, and cannot detect wooden studs, plastic pipes or live electrical cables.
