Important Limitations
Stud Finder is designed to assist — not replace — professional tools.
- Detects ferromagnetic metals only (steel nails, screws).
- Cannot reliably detect wooden studs without metal fasteners.
- Does not safely or reliably detect live electrical wiring.
- Accuracy depends on wall thickness, phone model, movement speed, and interference.
Tips for Best Results
- Move your phone slowly and steadily.
- Calibrate before each scan.
- Avoid nearby metal objects.
- Scan the same area multiple times.
