During renovations, installing shelves, or finishing work, it’s essential to know what’s hidden beneath the surface. The FNIRSI WD-01 is a practical cable and stud detector that can locate magnetic and non-magnetic metals (including copper), wooden elements, and electrical wires under voltage. This increases work safety and helps prevent damage to installations.
Two scanning modes are available for different situations: Deep and Exact. A modern detection module (HPC) with interference suppression reduces false alarms and improves accuracy. Once a target is found, the device guides you with colored LEDs (green/yellow/red) and an audible signal; when the center is reached, the sound changes to continuous. Also practical is the central positioning hole for precise marking of the drilling spot.
The compact, durable impact-resistant ABS body with non-slip sides fits well in the hand. The built-in lithium battery (300 mAh) charges via USB-C, so the detector is ready for regular use indoors and outdoors.

Notice: For electrical wires, detection primarily applies to wires under voltage. De-energized wires may not be detected, and measurements can be affected by the presence of metal objects.
