Complete entry-level certification with eLearning, pool sessions, and four ocean dives.
Next class starts in 4 days
This is the certification that opens everything else: once you hold Open Water, you can rent gear and book dives anywhere in the world without supervision, for the rest of your life. The card does not expire.
Key Largo is one of the easiest places on earth to learn. The reef sits in 20 to 35 feet of warm, generally calm water inside a protected marine park, so your first ocean dives are spent looking at turtles rather than fighting conditions. Academic work happens online before you arrive, which means your three days here are almost entirely in the water.

My instructor let me repeat it in the pool until I stopped panicking instead of pushing me into the ocean on schedule. Four students meant she had time for that. Certified on day three with 4 logged dives.

I finished the online portion on the plane and it made the three days almost entirely water time. Gear was newer than what I have rented since. Added nitrox at the end for a discount.

They noticed I was more comfortable in Spanish and switched. Small thing but it changed the whole course for me. The pool being on site meant a rainy morning did not cost us a day.
A PADI 5-Star Instructor Development Center that has certified divers in Key Largo since 1998. Every instructor on staff holds Master Instructor or higher and teaches full time rather than seasonally.
Yes. Open Water certification never expires. If you have not dived in a year or more, most operators recommend a refresher, but the card itself remains valid for life and is recognized worldwide.
You can complete remaining dives with us at no extra charge within 12 months, or request a referral form and finish them with any instructor in the world.
Yes — a 200-yard swim with no time limit and no specific stroke, plus a 10-minute float. It is a comfort test, not an athletic one.
Ages 10 to 14 earn Junior Open Water, which has depth limits and requires diving with a certified adult. It upgrades automatically at 15.
