Well, lets see. Besides trash, I have recovered several large boat anchors, a shopping cart, fishing gear, fishing nets, hats, bathing suits (bottoms and tops, hmmm), boat BBQ, dive knives, dive lights, dive watch, dive computer, Hawahiian sling, cell phone, GPS receiver, numerous sun glasses, various hand tools, diving weights/belts, lots of interesting bottles, a one-dollar bill, a bunch of goggles/masks/fins/snorkles, and then there was the salsa dish with the 1000 Peso coin in it that I found in Cozumel.
