Three Detection Modes for Every Need
The FNIRSI WD-02 stud finder metal detector is built to handle multiple detection tasks with ease. It includes three specialized detection modes:
-
Metal Detection Mode – Detects steel bars, rebars, metal joists, and metal pipes.
-
Wood Detection Mode – Locates wooden studs and joists accurately.
-
AC Wire Detection Mode – Identifies live AC wires to help prevent dangerous drilling accidents.
This makes it a truly multifunctional wall detector, suitable for everything from hanging shelves and TVs to large-scale interior renovation projects.
