| Zusammenfassung: | A buried metal detection which comprises an assembly of magnetically susceptible material (111) in at least one U-shape having parallel links (112) having sensing faces (114, 115), together with coils (113) are wound on each limb, the coils being supplied with current to produce an alternating electromagnetic field external to the assembly, means for moving the assembly or for switching the coils so that the field is aligned in different directions and at differing positions at different times, and monitoring means sensitive to variation in the energy supply drawn by the coils. |
