Extremely enjoyable. Tom is very entertaining and helpful. His knowledge of the Cayman diving scene (25 years) is excellent. You will laugh and learn during the surface interval. More

I made another dive trip from 3/29-4/4 and it was one of the best ever. Tom was great as usual and has added his son Danny as a divemaster. All of our dives were on the north wall. The fish and critter life was what I remenber from many years ago. Turtles, rays, an abundance of reef fish and numerous... More

Tom has certified over 30 members of our family and friends. These are young divers like my 17 year old son and old fah-ts like my 60+ year old brother.

Tom tought us how to do it in very little time and before we knew it, we were under the sea. We had such an amazing... More

I have been diving for 8 years, since I was 16. Myself and my family ONLY dive with Tom when vacationing on Grand Cayman. His wealth of knowledge of marine life, ecosystem, dive locations, safety, and his famous humor makes diving in Cayman the best quality experience you could ask for. PS: He does private charters for $1,000,000US. More
