Abstract
A magnetic coupler for inducing a signal on a buried utility wire. The coupler has two elongated jaws, each extending along a separate longitudinal axis. The jaws are attached at a hinge. The jaws may be placed about an exposed portion of the utility wire. A signal generate provides a signal which is emitted from a transmitter in each of the jaws. The signals emitted from each jaw are antiphase to one another, such that they are additive to a utility wire disposed between the jaws but out of phase with respect to any utility not between the jaws. The signal is thus induced on the utility wire and can be detected as emitted from its below ground length by a conventional locator.
