Great people and divers. Very helpful and informative on the area. No complaints here and will be back.

Also, right next door to the best happy hour in Key West per the locals. $6 mojitos, margaritas and rum runners plus 1/2 off all the apps (full size apps too :) @ The Boathouse!)

Great service and experience overall! Awesome staff who were all very helpful both on and off the boat, including our dive guide, Stormy. Save the owner is also incredibly nice and insightful. Thorough checks on our equipment, safety protocols, and dive/ snorkel briefings. We saw sharks, sting rays, eels, lion fish, lobsters, and very colorful schools of fish too.
