Abstract
Specific apparatus and associated methods are described for use in establishing the positions of locating field detectors and a sonde. Two detectors can be located at positions within the region, each being operable in a transmit mode and in a receive mode such that each one of the detectors in the transmit mode is able to transmit a relative locating signal to the other detector for use in determining the relative position of one detector in relation to the other and such that both detectors receive an electromagnetic locating signal from the sonde in the receive mode for use in determining the position of the sonde and the detectors within the region.
