What a great experience. We were all first time scuba drivers. I would recommend Tom and Danny to any first time divers. He made it simple and very comforting. Tom is a very good instructor. So happy we experienced this.

Who is the best Divemaster in Grand Cayman? Tom Burns, that's who! I have been diving with Tom for over 22 years. There are other good dive operation in Grand Cayman that I have tried but none compare to Cayman Marine Lab. Tom is the most knowledgable and entertaining. (Very dry sense of humor!) If you are looking for a... More

Since my husband is certified, and I have no experience, we chose to dive with CML given the rave reviews from folks on TripAdvisor. We expected to be diving with Tom, but the morning we arrived for the dive we were quickly handed off to Danny (Tom took on more experienced divers on a separate boat). While I felt I... More

I recently traveled to Cayman and had the privilege of diving with Tom and his son Danny. It was my first time diving and I had one of the most amazing experiences of my life! Danny walked me through the dive thoroughly and I felt extremely comfortable throughout each the dives. I agree with ‘Heckleman’s’ comments, “I recommend Tom's approach... More

I recently dove with Dr. Tom Byrnes with Cayman Marine Lab. It was terrific! Tom is extremely knowledgable and experienced. I really liked the small size of the groups he takes out. I felt extremely safe at all times.

Cayman Marine Lab don't call themselves "adventure divers" for nothing. They always pick the best, most interesting sites. When most dive operators are taking their customers to the worn out West sdie, Cayman Marine takes their guests to the North wall, one of the best wall dive areas in the world. When most dive operators treat you like children, Cayman... More

I have dived with Tom for 9 years and he is the the best! Knowledgeable, safety-conscious, and so very entertaining.

A once in a lifetime chance to interact with sea turtles. All kinds of marine life. We fed dolphins and sting rays. It was a wonderful experience and kids would love it!!

I grew up diving with Tom. He certified me, and I have yet to dive with another operation that I've enjoyed more. If you are looking for a highly educated dive master that brings together marine knowledge with entertaining conversations in between dives, look no further. CML is your operation.
