The NOYAFA NF-5102 wall scanner is designed to locate hidden metals, timber framing and energized AC wiring before drilling or installing fixtures. It helps homeowners and tradespeople assess walls before mounting shelves, brackets, lighting and other equipment.
Key features
- Detect ferrous metals such as steel and reinforcement up to 100 mm deep.
- Locate non-ferrous metals including copper and aluminum up to 80 mm.
- Detect energized AC wiring at depths up to 50 mm.
- Find timber framing members at depths up to 30 mm.
- On-screen indication supports positioning over a detected target.
- Compact format suitable for renovation and installation work.

Practical benefits and capabilities
NOYAFA NF-5102 helps survey a wall, ceiling or partition before drilling. It searches for metal, wooden structures and energized AC wiring, helping reduce the risk of damaging hidden services during installation.
Where it is used
- locating steel reinforcement and metal pipes before drilling
- finding wooden studs behind drywall
- preliminarily checking for live AC wiring around bracket locations
- installing shelves, TVs, furniture and cable ducts
- surveying walls before renovation or alteration
How to use the instrument
- Select the detection mode for metal, wood or energized AC wiring.
- Place the scanner against the surface and move it slowly, following the calibration instructions.
- Mark several high-indication points and scan again from another direction to narrow down the object location.
- Consult utility drawings and isolate relevant electrical circuits before drilling whenever possible.
Important guidelines and limitations
The 100 mm specification applies to magnetic metals, not hidden wires. Moisture, reinforcement and wall materials affect detection. Do not rely on the scanner alone when deciding whether it is safe to drill.
Frequently asked questions
Can NF-5102 find steel reinforcement?
Yes. The claimed maximum detection depth for magnetic metal, including steel, is up to 100 mm.
Can it detect a copper pipe?
Non-magnetic metal detection is specified up to 80 mm under suitable conditions.
How deep can it find electrical wiring?
For energized AC wiring, the specified maximum detection depth is 50 mm.
Can it locate wooden studs?
Yes. Wood detection is specified up to approximately 30 mm.
Does no signal mean drilling is safe?
No. Detection depends on depth, wall material, moisture and whether wiring is energized; a clear scan is not a safety guarantee.
NOYAFA NF-5102 is useful during renovation and mounting work where metal, wooden supports and electrical cables may be hidden behind a surface.
