Great to dive with Tom again. I did not recognise any of the divers, but the vast majority of them were long time clients, very competent, and friendly. Through my over three decades of diving, I have not found another dive operator that I enjoy diving with more than Tom. He has that "IT" factor. Great sense of humor and... More

Have just returned from a wonderful vacation on Grand Cayman...a true highlight of which is always diving with Tom Byrnes and Cayman Marine Lab. Tom and his assistant Paul run a fine operation - great small boat diving venue that provides lots of variety, and dives on virtually pristine sites...Most of the dives were anchor drops on sandy areas between...

This past trip to as my second time diving with Cayman Marine Lab and I wouldn't dive anywhere else! The smaller boat size is great and allows everyone to get in the water fast and smoothly. Overall it was a great experience and I had a great time.

Although the name sounds quite official, the service is anything but. Because it is a small outfit, the groups are small, with lots of personal attention. Tom is passionate about diving, and seeks to make sure the dive experience kindles similar passion in the customer. He picked out some outstanding sites. Since he is a marine biologist by training, he... More

I recently obtained my certification with Tom. I was nervous to stay the least and Paul the dive master put me at ease. I had a few panicked moments and he was able to help me relax and get me through all my skills, his moto was that he wanted me to be able to dive safely. I can't thank... More

We planned a last minute trip to Grand Cayman and really wanted to dive with Cayman Marine Lab after reading the reviews on Trip Advisor and Scubaboard. We were thrilled that they accommodated our last minute request and got us on a 2-tank afternoon dive. It was a short ride on a fast, small boat to 2 beautiful wall dives... More

Cayman Marine Lab is awesome! Tom took great care of our group during some challenging weather conditions. He took us to different parts of the island each day. We were west, south and north over a 5 day visit. It was very well organized and the diving was spectacular. The benefit of having several boats was a huge plus. He... More

Myself & my family have been diving with Cayman Marine Lab for over 20 years. Dr. Tom Byrnes is a great dive master and extremely knowledgeable about all the beautiful marine life, corals, etc. I would highly recommend diving with Tom if you want personal attention to every detail and a great time.

We completed our open water diving certification with CML. We did two dives the first day from Tom's boat and two shore dives the second day (due to some sea sickness). Paul and Tom were very understanding and flexible and we ended up doing two shore dives with Paul on the second day that were amazing. Paul was very patient... More
