Abstract
A method and apparatus locates buried objects in conductive soil by creating a direct current in a transmitting loop, periodically terminating the direct current in the transmitting loop to create an eddy current in the conductive soil using time domain induction, receiving a magnetic field resulting from the eddy current running through the conductive soil, and locating the buried object using the received magnetic field.
