I wish I was diving, but unfortunatly was only snorkeling, though I am very interested in learning to dive; I think I will take it up this summer. I was on the Island of Oahu, I found it to be very comercialized and would recommend going to one of the other Islands if you plan to go to Hawaii. The water was quite rough most days ,but we got a few farly still day in. (It was the beggining of there rainy time)
