The Faithfull 3-in-1 Detector is an electronic tool designed to locate concealed objects behind walls, ceilings, and floors, preventing accidental damage during home improvement tasks. It identifies wooden studwork, metal pipes, rebar, and live electrical cables by utilising an integrated LED and buzzer indicator system. Suitable for tasks such as hanging pictures, installing shelving, or drilling, this detector helps pinpoint secure fixing points. A built-in marking groove allows for precise surface identification before drilling or nailing. The device operates on a 9V 6F22 alkaline battery, which is included, and provides detection capabilities for various materials including electrical conduits and metallic objects. It is engineered to detect wooden studs up to 14mm deep and trace live cables at typical depths of 50mm.
