Had a nice night hunt at the beach a couple of days ago. I continues to amaze me the tiny targets I can find with this Equinox 800. Check out the two targets on the Mercury dime that I recovered that night. The little silver ring on the left rang up at 10 with a good solid signal. I'm not sure what it's made of....Aluminum? Silver? Looks like it may be a connecting link for a charm, bracelet, or earring dangler. The 14K earring back on the right was just a 1-2 depending on which mode I used. It was mostly a 2 in Gold 1 and 2 with a solid tone, a 1 in Park 2 with a fairly solid tone, and a weak, broken signal in Park 2. No signal in Park 1, Field 1, or either of the beach modes. This matches what I found with testing an 18K tiny link bracelet that I played with a few months ago. Sensitivity was at 22, other settings were stock.
