I have found a gold and jewel encrusted urn with sealed remains. We thought we found a treasure box till we brought it to the surface and found the funeral card which was held the previous weekend and honored a sailor who always wanted to be returned to the sea.
I've found a wrist dive computer, a pair of $300 Prada brand sunglasses, a $20 bill twice, a bucket filled with cement, 2 anchors, more masks, snorkels and fins than I'll ever be able to count, nice metal compass, 1/2 dozen knives, gun shells, a billion lures, a reel, a first aid kit case empty, integrated weight pouches complete with lead, hard weights, clippies clasps and snapons of all manner, 2 dive lights - both flooded, a prop, golf club with the wooden part broken off, golf balls, couple of bikini tops, hair scrunchies bands and barrets, bottles, bottle caps, a non-waterproof digital watch with metal clasp band, and an oxygen mask.
Most items had been down a long time - nearly encrusted all over.
