Took a dive trip yesterday to the Thunderbolt with Deep Blue. They required a guide go with us which is safer for sure. Guide was a man named Jeff who really knew his stuff. Had a great time !

All of our regular dives are less than 30 feet because our reefs are so shallow. We try to assign you with another diver but that i not always possible. In that case you can pay for a guide to accompany you on the dive.
