Abstract
The subject-matter of this invention is a device for locating rods buried in high-density reinforced concrete. The device envisages an inductor coil (10) which generates a magnetic field, and at least one detector coil (1) able to detect the variations in the magnetic field induced by the presence of steel rods. The device is associated with marking equipment (4), which may be controlled either manually or automatically, depending on the strength of the signal emitted by the detector coil(s).
