A walk-over tracking system is used to help guide and monitor the location of the bore. The system is comprised of a transmitter and receiver. The transmitter or sonde is located in a housing unit near the front of the drill string.  The transmitter emits a continuous magnetic signal, which is picked up by a portable hand-held receiver. Data transmitted to the receiver allows the tracking hand to determine position and depth as well as clock-face position of the drill bit. This information allows the operator to track location along the planned bore and to make changes as needed.
