1. A sonde device, comprising:
a waterproof housing:
a magnetic core disposed inside the housing, the magnetic core including:
a plurality of core section elements, each core section element in direct physical contact with one or more other of the core section elements;
an electronic circuit disposed within the housing, the electronic circuit configured to generate an alternating current signal output at one or more different predetermined frequencies; and
a coil assembly disposed along the length of the magnetic core, the coil assembly comprising a winding wound outside the plurality of core section elements, the winding being coupled to the output of the electronic circuit to receive the alternating current signal and generate a corresponding magnetic field dipole signal.
