About this product
This Faithfull detector is an electronic scanning tool for locating concealed objects behind walls, ceilings and floors before drilling or fixing. It offers three detection modes: wooden studwork (including centre-finding), metal such as pipes, nails, rebar and conduit, and live AC voltage cables, helping to avoid drilling into hazards such as pipes or wiring. Detection is shown via an LED and buzzer indicator system, with a marking groove at the top of the unit for marking the surface before drilling. Approximate detection depths are 14mm for a 30x30mm wood stud, 25mm for a 25mm diameter iron pipe, and 50mm for AC voltage at 90-250V, 50-60Hz. A 9V alkaline battery is included, allowing immediate use. It suits tasks such as finding fixing points for shelving or pictures, or tracing cables and pipes during installation work.
