I am still working on the design of an iron discriminating PI. As the new detector is slated for prospecting use as well as beach and inland detecting, hot rocks are a major issue. If anyone has any hot rocks lying around I will gladly buy them and /or pay the shipping. I am located in Charlotte, North Carolina, USA. Any and all hot rocks will help. I am also very interested in obtaining some specimens from the Australian goldfields. Thanks in advance Dave. * * *
