Abstract
A method for choosing a frequency to locate an underground object. A locating receiver is provided with a display. The locating receiver scans multiple pre-selected frequencies to determine a noise level, or a signal-to-noise ratio. The locating receiver transmits the chosen frequency to a transmitter, which places the chosen frequency on the underground object to provide an optimal locating frequency.
