Product Overview:
The FNIRSI WD-02 is a high-precision, smart wall detector and multi-material scanner, engineered to detect hidden studs, metal, live wires, and other objects behind walls with exceptional accuracy. Designed for DIY users, electricians, contractors, and home renovators, this device ensures safe and efficient drilling, nailing, and installation by identifying hidden hazards and structural elements before you begin.

Equipped with a bright LCD display, intuitive controls, and multiple scanning modes, the WD-02 delivers real-time visual and audible feedback to help you confidently detect wood studs, metal pipes, rebars, copper wiring, and live AC cables behind drywall, concrete, and other wall surfaces.

Key Features:

4-in-1 Multi-Material Detection
Detects wood studs, ferrous/non-ferrous metals, live AC wires, and general wall cavities. Ideal for home projects, electrical work, and construction site safety.

High-Accuracy Scanning
Advanced sensors provide pinpoint detection of objects up to up to 50mm (2 inches) deep in walls. Reduces guesswork and prevents damage to hidden structures.

Smart LCD Display Interface
Large backlit LCD screen shows real-time scanning feedback, material type indicators, object depth, and warning symbols for live wires—enhancing accuracy and user safety.

Live Wire Warning System

Alerts you when the device detects AC current, reducing the risk of electric shock or equipment damage during wall drilling or cutting.

Auto Calibration & One-Touch Operation
Automatically calibrates to the wall surface with one press, ensuring reliable readings even on uneven or painted walls.

Ergonomic & Portable Design
Lightweight and easy to grip, with a non-slip exterior for secure handling during extended use. Compact enough for toolboxes and on-the-go use.
