Currently, houses must be built to place shielding features such as beams, columns, joists and other support items under walls and floors, and to lay various types of wires and hardware under walls and floors. After the floor and wall surfaces are laid, it is often necessary to cut or drill into the support surface or to provide openings in the surface, as required by the various types of finishing, but at the same time it is necessary to avoid damaging the underlying support objects, wires, pipes, etc. In these cases, it is often desirable for the constructor to know exactly where the support object is behind the wall or floor before starting to cut or drill into them. In other cases, a constructor may also often wish to anchor weights to concealed support elements to ensure the soundness of the anchorage, in which case the constructor then often wishes to install fasteners on surfaces aligned with the underlying support elements. However, once the surface of the wall and floor etc. is finished in place, the positions of the various support elements, wires and pipes cannot be detected by the naked eye or the like.
