The VELLEMAN K7102 Metal Detector Kit is a practical electronic detection device designed to help locate concealed metal objects behind walls, ceilings, and floors before drilling or cutting. Ideal for DIY enthusiasts, installers, maintenance technicians, and electronics hobbyists, this kit helps reduce the risk of accidentally damaging hidden electrical wiring, water pipes, gas lines, central heating pipes, and other metallic objects during construction or renovation work.
The detector uses an adjustable sensing circuit capable of detecting metal objects at distances of up to 8cm (3.15 inches), depending on the size and type of the object being detected. The adjustable sensitivity allows users to optimise performance for different building materials and detection requirements.
A bright LED indicator provides instant visual notification whenever metal is detected nearby, making it easy to identify safe drilling locations. For applications where an audible warning is preferred, the PCB includes provision for connecting an optional buzzer, allowing both visual and audio indication of detected objects.
The PCB has been specifically designed to fit neatly inside a separately available enclosure, resulting in a compact, professional-looking handheld detector suitable for everyday use around the home, workshop, or job site.
Powered by a standard 9V battery (not included), the K7102 offers completely portable operation without requiring mains power, making it convenient for use in confined spaces or remote locations.
Supplied as a self-assembly kit, the VELLEMAN K7102 provides an enjoyable electronics project while producing a useful tool that can help prevent costly repairs, electrical hazards, and accidental damage during installation work.
Whether you're hanging shelves, installing cabinets, mounting televisions, fitting electrical equipment, or carrying out general building maintenance, the K7102 helps you work more safely by locating hidden metal before you drill.
