Spring came early, so I could get up into the mountains in my pursuit of native copper. There are very few locations in Japan with copper as pure as what I brought home with me last week. The largest piece was 4~5 kg. I'm a mineral and fossil dealer, so the Vanquish 540 has more than paid for itself...again. More than enough money to upgrade to an Equinox and let my grandson use the Vanquish when he goes treasure hunting with me.
