Abstract
A device is described for use as part of a system in which a transmitter is moved through the ground while transmitting a signal that can be used to locate the transmitter. The device includes a receiver for receiving the signal to generate certain information about the position of the transmitter relative to the position of the device based on the signal. A processor establishes a current location of the transmitter and records the current location as one of a series of recorded locations of the transmitter based on the certain information and, at a time of recording the current location, electronically records a time stamp that designates at least the time at which the current location was recorded as part of the series of recorded locations of the transmitter.
