I rarely get chains, let alone this small. Was about knee deep in the wash and the AQ hit on this one. Did not come up on the first scoop but did on the second scoop. No good way to know how deep it was but it is heard well on the AQ in the air at 4 inces and fades out around 5 inches. It is next to a dime I dug today. Not sure if I hit on the clasp or the little balls on the chain. I tested it with the Excal and need to be about an inch or closer to the coil to hear anything in all metal and scraping the coil to get it in disc mode with disc set on minimum ... it nulls at 1/2 an inch and nothing at an inch in disc.
