1. An inductive clamp for use in utility locate operations to inductively couple current signals generated in a transmitter to a hidden or buried conductor, comprising:

  • a head assembly including a base element and a plurality of movable arm elements mechanically coupled to the base element;

    a utility selector element coupled to the head assembly of the inductive clamp for providing, via a communications link, user selected utility type data to the transmitter;

    a magnetic core subassembly, disposed in the arm elements, for generating a magnetic field for coupling to a targeted utility, the magnetic core subassembly including one or more ferrite elements and a wire winding wrapped about the one or more ferrite elements; and

    an electrical connector input to receive the current signal from a transmitter cable and provide the current signal to the wire winding.
