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

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!!

Nobody knows the briny deep like Cap’n Tommy. From his fine schoolin’ he can tell ya a Barracudy from a bikini cutie, every time. Not an easy chore in the Cayman Isles.
