In May and June 2007, I went TDY to Hawaii. I did my AOW certification with the guys from Dive Oahu. They have a great bunch of Instructors. They really made my expirience worth while. They primarily rotate between three wrecks and six reefs right off of Waikiki. We saw spinner dolphins on our first morning out. The Brownies that Capt Bill "made" himself really made the time between dives enjoyable. The Sea Tiger is a great dive for anyone who is just starting out. The Turtle that calls it home is huge. I can`t say that I had a bad dive the whole time I was with them. I would definitely recommend it for anyone going down to Hawaii.
