My wife and I do not go on shark dives where feeding occurs. Lots of people do, and that's there business. In order to dive with sharks, you need to go where the sharks are. In the Carribean, that is almost everywhere. We have enjoyed nurse sharks in Mexico south of Playa del Carmen, have seen lots of grey reef sharks in the southern Bahamas without feeding them, often see white tipped reef sharks in Hawaii (on Maui at a site called Mala Pier you will see them on nearly every dive), hammerhead sharks off Molokai, and regularly see nurse sharks off Key Largo. We saw sharks in Beqa Lagoon, Fiji, while NOT on the shark dive. Finally, I did see a large tiger shark at Molkini Crater, Hawaii back wall a couple of years back. None of these was a shark feeding encounter. Just saying.
