I did it a year ago, it was very fun. I just convinced myself if I followed the instructions and remained calm I would be fine. But dont let anyone kid you, these are wild sharks and a few ppl have been bitten when they did not follow instructions and the feeders get nipped from time to time. The groupers are as entertaining as the sharks. I think most every diver should do this dive just to get a little more realistic experience with sharks to help you overcome the negative image of them we all get from the media. Enjoy!
