1. A metal detector adapted to generate a transmit search signal and to receive a receive search signal, and to analyse such received search signal,wherein the detector is adapted to allow a selection of operating parameters for said receipt and analysis, said selection being effected by storage of data in a memory,characterised in that the detectoris adapted to allow such stored data to be modified to align with stored data in an external store, wherein the external store is a memory which is both outside of and spaced from the metal detector, and also from the memory within the metal detector which stores the data effecting the operating parameters;

  • further comprising a digital data communication program, adapted to effect a transmission of some or all of the stored data through a data transmission link, thereby enabling a further metal detector to receive and store, for use in such further detector, said data,and wherein the operating parameters to be selected include a discrimination pattern, said discrimination pattern including at least one range of amplitude of a conductance component of a receive search signal and at least one range of amplitude of an inductive component of a receive search signal.
