noyafa NF-5102 3-in-1 Stud Finder Wall Scanner measurement tool

3-in-1 wall scanner

The Noyafa NF-5102 is a digital stud finder that detects wood studs up to 30 mm, metal up to 100 mm and live AC wires up to 50 mm behind walls. A high-precision anti-interference chip reduces false alarms while the HD dial backlit screen shows real-time signal strength and centre positioning. It runs on a rechargeable 3.7 V 390 mAh battery with Type-C charging and auto-off after 10 minutes. The IP54-rated housing suits residential and light commercial use.

DIY renovators and electricians

This tool suits anyone who needs to locate studs, pipes or live cables before drilling or cutting in drywall, plaster or timber frames. The audible alarm with adjustable volume and mute option helps in noisy environments. Builders who require deeper scanning through thick concrete or multiple layers should look at alternative equipment. Users wanting wireless data logging or smartphone integration will not find those features here.

Detection depth decides fit

The maximum sensing depths — 30 mm for wood, 50 mm for live AC wire and 100 mm for metal — determine whether the NF-5102 reaches the targets in your wall construction. If your studs, pipes or cables lie deeper than these figures, this model will not reliably locate them.
