摘要:
A transmitter transmits a locating signal from a boring tool by operating at a frequency that is selected as one of at least two operating frequencies for use in locating the boring tool. A receiver, forming part of the locator, cooperates with the locator to cause the locator to respond dynamically to a change of the selected one of the operating frequencies such that the locator tracks the selected operating frequency.
