howdy folks.I bought a gpz 5000 awhile ago and was pretty clueless how to use it even after reading the manual. So, at the suggestion of a long time friend whose been prospecting for years I did the minelab intro course. -money well spent! Anyway, I found my first nugget ! {more of a speck, but allow me my moment of glory}. I'll post pics later .{ bit like a proud dad}.
