Abstract
Buried object locator systems including transmitters and associated buried object locators using phase-synchronized signals are disclosed. A transmitter may generate output current signals that are phase-synchronized such that an associated locator may receive magnetic field signals from the output current signal and determine information about the current flow based on independent phase-synchronization timing information.
