Abstract: Systems and methods for locating buried utilities in conjunction with associated electro-magnetic marker devices are disclosed. A marker device may include a marker device antenna and an electronic circuit operatively coupled to the marker device antenna. The electronic circuit may include at least two resonant circuits, including a first resonant circuit formed in combination with the marker device antenna for receiving an excitation signal at a first frequency from a marker excitation device. The received excitation signal may be converted into a power supply by a power circuit for powering the electronic circuit. Responsive to the received excitation signal, a processing element provided in the electronic circuit may generate an output signal at a second frequency, which is substantially different from the first frequency. The generated output signal may be tuned by a second resonant circuit and provided to the marker device antenna.
