A method for improving a sensitivity of a metal detector by reducing an unwanted magnetic field generated by at least one electrically conductive element of the metal detector, the metal detector transmitting a transmit magnetic field into a soil and a possible target within the soil which in response generate a response magnetic field, the method including the step of: redirecting at least a portion of the response magnetic field from entering the at least one electrically conductive element, wherein otherwise the at least one electrically conductive element within an influence of the response magnetic field generates the unwanted magnetic field due to a change in an intensity of the response magnetic field entering the at least one electrically conductive element, the redirecting adapted to reduce or eliminate the unwanted magnetic field generated by the at least one electrically conductive element thereby improving the sensitivity of the metal detector. |
