We dove with Bobby when we were in Maui about six years ago. It was my first ever dive and even though I am now certified I can honestly say I have never since felt as comfortable and natural in the water as I did with him as our guide. He was absolutely fantastic, knowledgeable, funny, comforting, and safe. We are heading back to Hawaii(FINALLY!) this weekend, and I really hope to do another dive with him. I wish I could give him six stars.
