If you don't have gold as a test try using different size bits of lead I, I put little bits that I Weighed from 0.03 up to a gram and put them in plastic containers. Is great for me and my grandson
Just watching the latest Aussie Gold Hunters there is a couple detecting in the Palmer river area and are using a petrol powered pump to run I highbanker?????? .. only on tv lol
Great information, was looking at the season pass but out of my price range as I would only use it for 2-4 weeks out of the year but very keen to come up .
