Everyone has their favorites and of course you will gets lots of differing opinions. I really react when I see someone say "so and so is the best."
DO NOT make an advance committment. Get here, take your list from this board and visit them. Elbert Greer who is an instructor at Ramon's just sat down beside me with his ice cream. He said there is a great picture of him at www.scubalessonsbelize.com
He's so modest. To tell the truth I have never dove with Elbert but he is a friend and a very funny guy. Been living here 15 years, writes a column for the local paper etc.
I also happy to really like Billy Leslie at Hustler Eco Tours. I've been diving with him since 1998. Billy is a master instructor - that means he instructs instructors. He is also very entertaining.
I love Everette Anderson - one of Billy's students. Everette is now an independent and gives private lessons. He taught my daughter in December and she is coming back in April. A guy in my villa just came down from Illinois and used Everett. Five of us joined him on this last open water dives.
Ched Cabral is also an independent here. So you have lots to choose from.
It is alwasy best to do the class room work at home and bring a referral.
