Groundradar’s Australian partners, Core Geophysics, has undertaken a series of extensive surveys in rural Western Australia to map paleochannels anticipated to contain diamonds for POZ Minerals.  POZ has published an excellent video explaining the exploration program using UltraGPR here: https://www.youtube.com/watch?v=UeTNv5scIJU.  The video also discusses failed attempts using consumer-grade radar systems to map the paleochannels.
