Abstract
A resonant assembly for identification of a buried asset comprising first and second resonant members each configured to resonate at a respective different resonant frequency when excited by an electromagnetic field. The resonant assembly is arranged to cause a near-field coupling of transmit and receive antenna of a detector at the first and second resonant frequencies such that identification of the resonant assembly is performed at least in part according to the frequencies of the coupling.
