Finally my first gold ring dig...and an unusual one at that

I've been hunting with Garrett AT Pro for about 5 months now and it's been a blast. I had gotten to wondering though why I hadn't been hitting any gold. I had found a 14k hoop earring but it was a surface find, I hadn't even made it to swinging the detector over it. I got to looking at a few videos on YouTube and looking at the VDI numbers on this forum and viola, I hadn't been digging those low numbers.....thought it was all foil.So the next day I'm off to hunt the areas I had already hunted in search of GOLD! But no luck, just a BUNCH of foil, pull tabs and ripped up cans, I did find a few more coins I had stepped over. So I grab a bunch of the wife's and my jewelry run out in the back yard with a couple of pieces of the foil I had dug, find a halfway clean spot, throw all the jewelry out and boy was I surprised! 2 of the necklaces I had thrown down (and one was a heavy 14k box chain) didn't hardly hit at all, especially the lighter weight one....it rang up about 28 at the most (video to come). I learned yesterday, although it's preached mostly all over the web, dig, dig, dig, dig everything. (I say mostly because I saw a YouTube vid the other day the guy was eliminating his 40's and 50's on his AT Pro and was talking about looking for gold....not watching any more of his vids) So yesterday I'm re-hunting a baseball field discrimination at 20 sensitivity on full nothing eliminated, about 3 hours in and after digging about 100 targets of junk, I hit Gold! She is apparently an infants ring, never seen one this small. It rang up as a solid 44 and was down about 2 inches, and apparently, according to my diamond tester the stone is real, I think it's a ruby, (the ring is hollow behind the stone, normally indicating a real stone). So I learned 3 things this week, I've had my discrimination too high (I was running 30), DIG those lower numbers, and quit walking so fast. Oh and wear those headphones....listen for those faint hits, it may be a necklace!
