Learn to Dive

Open Water Certification


The most popular course issues PADI’s Open Water Scuba Diver certification. Successful completion of this course grants you a certification to dive with a buddy to any dive site in the world shallower than 60feet/18meters. Hydra allows you to complete the academics online, on your own time, before the scheduled class starts. After you complete the learning that we supply you, we will coordinate a 4-day course for you to develop your comfort underwater. Typically, this is over two weekends, but we can also run 4 consecutive, or semi-consecutive, days. This course is open to anyone 10 years and older.

Key Largo Diver Course

We also offer a Key Largo Diver course, perfectly suited for exploring the dive sites throughout John Pennekamp Coral Reef State Park. We host this 2-day experience with a minimum of two dives in Florida Keys National Marine Sanctuary, but many more dives can be added for a diverse diving package. This course finishes with a PADI Scuba Diver certification to allow you a lifetime of diving with a professional in any of the shallow sites in Key Largo and around the world.
