just a couple examples of where i found a pendant - then spiraled out from it to find the chain
gold one was from saltwater shallows at a spot they body surf at (ive averaged a chain a visit there i believe because of the body surfers)
chain was a few feet away
The other is large silver = found pendant in thigh deep water and spiraled out to get the chain a few feet away
have gotten others the same way
