Tom is the best. Loved the dives we did.

Visit Date: September 2011

I've been diving with Dr. Tom for 20 years and for one simple reason....he's the BEST! Tom dives sites not frequented by all the other resort dive operations, and he will point out amazing things each time. This time we saw a hammerhead, a nurse shark, lobster, and tons of fish. He also killed about 40 lion fish who are invading the reefs and eating our beloved reef fish.

Tom Byrnes, owner of Cayman Marine Lab, obviously has a longtime love of the ocean around the Cayman Islands. It seems he personally knows every fish and ray he sees plus can tell you about the critter's habits. Nine divers ~ myself and eight others ~ is the most number of guests I've seen on his boats when I've gone out. I do miss Nutty, his Jack Russell terrier, being on the boat ~ she was great, barking at the wake of the boat!

WOW - Tom is really geared towards TAKING you diving - no fluff but boy does he get you to the most amazing dive spots on North Wall. Last weekend did 4 dives with Tom and 2 of them anchor drops where there is very little diving - WOW - 2 eagle rays swam right by us and we got to see a neck crab, a very impressive nurse shark along with a cool scorpion fish, spotted moray eel and Candice had an arrow crab and spaghetti worm dance on her hands ... Tom's boats are safe and his sense of humour makes the trip fun. Being a marine biologist he imparts awesome information and taught us about the stinging sin spines found not only on the dorsal area of the Lion fish built also on the very extremities of the caudal fins - interesting. We were on the boat with 5 other divers and it was comfortable. Entry is a backward roll and Tom is with you the entire dive and taking your gear off before you climb back on the boat. Nice touch :) cannot wait for this weekend as we will be going out again.

Thanks Tom.

Visit Date: November 2009

I have had the pleaseure of diving with Tom Byrnes of Cayman Marine Lab. on my last couple of visits to Grand Cayman.

My first visit which was during the early part of June 07, was off North Sound and in the couple of days of diving, I saw my first Hammerhead diving Lemon Reef.  The second trip, which was during November 09 was a blast, spending four or five days diving off 7 Mile Beach.

Tom is very knowledgeable about the local dive sites and ecology.  He runs an intimate operation with a relaxed, comfortable atmosphere and his long experience with the island really shows. He's also very friendly and attentive to his customers. I can't imagine going out with any other outfit.
