Best Diving and Guide Ever!
Reviewed October 7, 2014
We did four dives with Cayman Marine Lab between Sept 27 - Oct 4, and it was the best. First and foremost, Tom seems to know the Cayman waters like the back of his hand. I understand he's been diving those waters for 25 yrs or something like that. We dropped anchor on the north wall for each dive this trip, and it was like we were swimming through coral fingers that have never been disturbed to any degree. We saw sting rays, eagle rays, massive turtles, lion fish, thousands of fish of all kinds, and with unlimited visibility. I feel like I'm pretty good at spotting stuff, but Tom was pointing out stuff that I would have missed, no question about it... like a dive whisperer or something. I've dove north, south, and west sides of the island, with all different companies.... but it's always better with Cayman Marine Lab. I cannot wait to go back.

Return to Cayman and Cayman Marine Lab after 10 year absence

Grand Cayman is a wonderful vacation destination. New roads, new hotels and many new, wonderful restaurants - all in all, a lot of positive change. We were there eleven days had 7 two tank dive days, all with Cayman Marine Lab. Yes,Tom has a new dive boat and a new zealous disdain for Lion Fish, but diving with CML was the same as it had been and just as good as we had remembered it. The dive sites he chooses are apparently not subjected to high volume dive operators. We saw turtles, barracuda, shark, eels, grouper, lobsters, eagle rays as well as an array of sponges and smaller reef fish. God willing, we will be back, diving with CML next year.

Great Trip

Thanks Tom!! This was a great trip. I went on this dive off a cruise boat and there were no hiccups. I communicated with Tom via email and never missed a beat. The places we dove were off the beaten path and there were no other dive boats around. Tom is incredibly knowledgeable, which was exactly what I was looking for. I am an NAUI instructor and will definitely be bringing groups of other instructors as well as open water divers.

My family has been diving with Cayman Marine Labs for the last 24 years. They run an excellent dive operation and we will continue to dive with them in the future! Can't wait for our next trip!

Perfect Diving Day on the North Wall

Thanks again Tom Byrnes. Your Cayman Marine Lab outfit was very accommodating for my daughter and me as we scrambled for a late-morning dive during our March 2014 visit to Grand Cayman. And your Captain Dylan provided a spectacular afternoon with Cayman Marine Lab on the North Wall.

We are grateful to have found you! We really enjoyed Dylan's calm expertise and knowledge of marine life, as well as the more personal experience of a less-populated, more relaxed Cayman dive boat.

What a beautiful setting on the North Wall: The big, gliding turtle off the ledge reminded us of Finding Nemo!

See you next March. Cayman Marine Lab is our new dive outfit in Cayman. I will mention your outfit to any who seek great guides scuba-diving in Cayman.
