“Great dive charter! Will definitely be first on my list to call when heading to Key Largo. Super easy going crew with no attitudes. Michael and Carrie are great!”— Diane M., Google · November 2025
“We had a wonderful day snorkeling. Very accommodating for our 8-month to 80-year-old passengers. We saw more fish than on any other snorkel trip we’ve been on — dolphins, sharks, barracuda, large parrot fish and more!”— Kim S., TripAdvisor · December 2025
“Carrie took us to lobster, eel, turtle, tons of fish and coral, and the most magnificent Eagle Ray I’ve ever seen — wingspan must have been 8 feet wide. Both Michael and Carrie made us feel safe and looked-after. We WILL be back!”— Shanon E., TripAdvisor · October 2025
