In the wet sand a solid 77 VDI, loud and clear, three scoops and in the hole, a big old gold chain, my pacemaker skipped a beat. I rinsed it off and started looking for a mark and BAM I see 14K. I stuck it in the bag the sun was just coming up I would get a better look at it when the sun comes up. After 30 minutes I pull it out to get a better look and it looked like corrosion on the clasp and parts of the chain. I pulled out the magnet and no part of the chain stuck to it, so I was feeling a little bit better about it. I will order an acid tester when I get home to find out for sure. In addition, I stumbled on this sterling bracelet surface find in the dry sand, another great day metal detecting. Any advice good or bad?
