If this dive shop is good enough for Flipper, most likely it will be good enough for you. The pros at Miami Seaquarium drive across the Rickenbacker Causeway regularly to get their tanks filled and equipment repaired by the guys at Bubbles. As a shop, they offer the latest gear from SeaQuest, Mares, and other top brands. As a dive school, the instructors offer open-water dive certification -- a two-week course for $249 that includes at least four open-water dives. They also offer advanced courses and a first-aid course. The Bubbles crew even acts as travel agent, organizing dive trips to several hot spots, including Belize and Colombia. But if you don't want to go that far, they offer Saturday reef dives and Sunday wreck dives as well as spooky night dives on Wednesdays.
