Hi there digahole, Just to confirm....it was .06 not .6. Ten times smaller than a .6 gram piece.
To be honest it was probably almost a sunbaker. One scrape with the pick & it had moved, but the other sub gram pieces gobsmack me as to how deep some of those are. The signal can be quite loud & makes you think it is going to be a bigger piece than it often turns out to be. Guess I am still getting my head around the audio as compared to my old GP 3000.
I know that one of the sub gram bits was down a good 6" & it was a nice distinct signal from the surface & just got crisper & louder as I got down to it. It was a real bastard to get in my hand as it was right down it the tightly packed schist & took some smashing of the rock to finaly get it out. I was sure it was going to be well over 1 gram....but it wasnt. I checked the dig to make sure there wasnt another piece lurking....as there often can be...but this time there wasnt.
The 1.3 gram piece was a real scream of a signal & I wouldnt have been suprised if it was a .22 shell or bullet head, but once I was breaking in to the schist & the signal was still in there my confidence of it being gold raised to 99% sure. This time there did turn out to be a smaller piece when I re scaned the hole after pocketing the 1.3 grammer. The 1.3 gram piece was down about 6 inches too.
These are old sluiced workings that I am detecting in & the old timers have washed down to the bed rock so the ground isnt deep at all. Just the odd crevice that goes down a bit & that is where the gold is trapped. I have also been over this ground with my old GP 3000 so the bigger gold has pretty much all gone. I am suprised though at what I am getting with the GPX 4500....not that I am complaining as it makes me feel that I was justerfied in spending the money on an upgrade to the later technology, which seems to be paying off.
Thanks
Good luck out there
