The earliest stud finders detected ferrous metals using compasslike pivoting magnets. Even though only commercial buildings use metal studs, magnetic stud finders, which are still available, work with wooden studs, too, by locating the metal nails used to mount the wallboard or wooden lath.
Do stud finders detect metal or wood?
Stud finders are little devices used to locate the beam of wood, metal, wiring running through drywall, so you can find something strong to screw things too. They're incredibly useful and you can find a HUGE range of them online.
Are all stud finders the same?
There are two basic types of sensors used in stud finders: electronic and magnetic. Electronic stud finders run on batteries. They work by detecting changes in the density of the surface being scanned.
Do all stud finders use magnets?
Stud finders fall into two basic categories based on the method they use to detect studs, either magnetic or electronic.

What do stud finders detect?
Low-end stud finders use magnets or electricity to detect a stud. These stud finders detect the fasteners in the drywall and alert the user once the magnet is attracted to the metal fastener.
Will a stud finder find a pipe?
A stud-finder uses a sensor to locate wires or pipes behind the plasterboard. Place the stud-finder on the wall and press the activating button. Slowly slide it in one direction until the indicator light glows and there is a beeping sound. Most stud-finders will locate pipes and electrical cables as well as timber.
Do stud finders work through wood?
The reason is that stud finders are designed to scan through sheet materials, such as drywall or plywood that have a fairly smooth surface and consistent thickness and density. A typical asphalt shingle roof has a layer of wood based sheet material, usually plywood or chipboard, and normally with a layer of tar paper.
Can you use phone as stud finder?
Stud finder app for iOS and Android brings the simplicity and effectiveness of a real stud detector tool to your iPhone or Android device. The app uses your device's compass (magnetometer sensor) to pinpoint metal studs, nails, and screws embedded in all wood wall studs.
Should you drill into a stud?
If you're hanging shelves or mounting anything heavy to the wall, you'll probably want to mount it directly to the wall studs. However, you should be drilling pilot holes first before driving in any screws.
Can I use my iPhone as a stud finder?
First, no iPhone app can locate 2x4s because phone hardware generally doesn't include an electromagnetic density sensor to find wooden studs.
Why are stud finders so unreliable?
Finding Live Circuits Behind Walls Most magnet-type stud finders don't work effectively since they reply on locating the fasteners (screws) used to secure the drywall. These can be very difficult to locate.
Do stud finders detect wires?
There are two kinds of stud finders that can help you find wires in a wall – magnetic and electric. A magnetic stud finder is used to detect metal nails in wall studs. Electronic stud finders produce a tiny electrical field that changes when the finder reaches a denser region in a wall.
Do wall studs have metal?
What is a wall stud? Studs are vertical 2 by 4 inch beams that support the frame of your home. You can find them behind your drywall, usually spaced 16 or 24 inches apart. Since studs are made of thick and sturdy wood or metal, they can securely hold screws better than wall materials like drywall.
Will a magnet work through drywall?
The big block magnet outside the wall can move the ring magnet around quite well, even through thick drywall. To show a “cutaway” view of the idea, see how they attract through a thick textbook. Magnets as strong as these work well through ½” or 5/8” drywall.
How do I find screws in drywall?
Run a magnet up and down the length of the stud, starting several inches in from the edge of the stud. Next, move over 16 to 24 inches to the next stud to find the next row of screws. Move the magnet slowly along the wall until you find the screws you want.
Do all walls have studs?
Can a wall not have studs? The answer is no—a wall must have studs to ensure structural support. However, there are some variations in how a wall can be framed and where you will locate studs.
What does it mean when a stud finder beeps?
Most stud finder models will indicate the edges of a stud – only Zircon® Center Finding StudSensor™ tools will indicate the center. If the tool blinks and beeps continuously, there is a calibration error. Try scanning the wall again, but start in a different location.
How do I know if I have metal studs?
If you think your home might have steel studs, you can check by running a magnet along a wall. While nails and screws in wood studs will attract a magnet, steel studs will have a stronger attraction along the entire height of the stud. An electronic wall stud finder can also detect metal in a wall.
Will a stud finder detect copper?
Do not use a magnetic stud finder to attempt to find copper pipes. Copper is not a magnetic metal, so it won't be detected by magnetic tools.
Can stud finders be wrong?
Even though your tool indicated that it located a stud right where you need it, a stud finder can signal false positives when there is metal piping or flashing or brackets within the wall.
Will a stud finder work on a roof?
High-density stud finders will see through the plywood and find the rafters inside the attic. These stud finders work the same way as normal stud finders but cost more. Hold the HD stud finder approximately 1 inch away from the roof surface and slide it across the roof. The finder beeps when it finds a stud.
How far apart are studs?
The general spacing for wall studs is 16 inches on center, but they can be 24 inches.
Why is there plywood behind drywall?
It's laterally structural to support the building's side-to-side forces. Penetrations in your shear wall must adhere to different restrictions than other walls and you may need to consult an engineer to verify.
