ABSTRACT:
A system in which a boring tool is urged through the ground by means of a drill string in order to form an underground hole is disclosed herein along with an arrangement for obtaining certain information at the boring tool during operation of the boring tool. That arrangement includes a transducer carried by the boring tool for generating an AC signal containing desired information and means for connecting the transducer directly to the drill string and to the surrounding ground for transmitting the information containing signal to an above ground location.
