The first industrial metal detectors were developed in the 1960s for a variety of purposes, including mineral prospecting and other industrial applications. They are also used to detect land mines, as well as weapons such as knives and guns, especially in airport security checks. Geophysical prospecting, archaeology, and treasure hunting are other uses for metal detectors. Additionally, they are employed to find foreign objects in food, and in construction to locate steel reinforcing bars in concrete, pipes, and wires buried in walls and floors.
