Product Information
Full details
The Stanley 47-400 Magnetic Stud Finder is designed for DIYers and professionals needing to reliably locate wall studs. Its primary benefit is the powerful magnet that directly detects metal fasteners, simplifying the search for studs behind drywall. A potential limitation is its reliance on the presence of metal fasteners, meaning it won't detect studs without them. Key features include its magnetic detection mechanism and a notched base for easy marking.

FAQs
How does the Stanley 47-400 find studs?
It uses a strong magnet to detect steel nails and screws that are used to attach drywall to wall studs. When the magnet senses these metal fasteners, it indicates the presence of a stud.
Does this stud finder need batteries?
No, the Stanley 47-400 is a magnetic stud finder and does not require any batteries to operate.
What types of walls can I use this on?
It is most effective on standard drywall and plaster walls where metal fasteners are used. Its performance may vary on thicker materials or walls without metal fasteners.
Can it find wood studs directly?
No, this stud finder only detects the metal fasteners (nails or screws) holding the wall material to the stud. It does not directly detect wood.
How do I mark the stud location?
Once you feel the magnetic pull indicating a stud, use the notched base of the stud finder to conveniently mark the wall surface.
What if there are no metal fasteners on my wall?
If your wall covering is attached without metal fasteners, or if the fasteners are too deep to detect, this magnetic stud finder will not be able to locate the studs.
Is this better than an electronic stud finder?
It depends on your needs. This magnetic finder is simple, requires no power, and is generally more affordable. Electronic finders can detect stud edges and centerlines without relying on metal fasteners, but require batteries and calibration.
Troubleshooting
No magnetic pull detected.
Ensure you are close enough to a metal fastener. Try scanning slightly higher or lower. Verify that the wall covering is not excessively thick or made of a material that interferes with magnetism.
Difficulty marking the stud location.
Ensure the stud finder is held flat against the wall. Use the notch to make a clear mark. If needed, use a pencil to make a secondary mark adjacent to the notch.
Stud finder sticks to unintended objects.
This can occur near electrical boxes, plumbing, or metal framing elements. Move the finder away from these areas and scan systematically.
Pros and Cons
Pros
- No batteries required, always ready to use.
- Directly detects metal fasteners for stud location.
- Integrated marking notch for convenience.
- Compact and easy to store.
- Affordable price point.
Cons
- Only detects studs with metal fasteners (nails/screws).
- May be less effective on very thick drywall or multiple layers.
- Does not detect wood studs directly.
- Requires user to interpret magnetic pull.
- Less precise than electronic stud finders for exact edges.
Setup, Compatibility & Care
Setup: This stud finder requires no setup. It is ready to use immediately. Ensure the surface you are scanning is relatively clean to maximize magnetic contact.
Compatibility: The Stanley 47-400 is designed for use on standard drywall and plaster walls. Its effectiveness is dependent on the presence of steel nails or screws used to attach the wall covering to the studs. It will not detect studs made of materials other than metal or those secured without metal fasteners.
Care: To care for your stud finder, wipe it clean with a dry or slightly damp cloth after use. Avoid submerging it in water or using harsh cleaning chemicals. Store it in a dry place to prevent rust or damage to the magnet.
