Day 1 and 2: Classroom and Confined Waters
The first two days are split between theory sessions—some online, some in person—and practical exercises in shallow waters. Here, you’ll learn essential diving principles like equipment use, safety procedures, and underwater communication. The in-water sessions take place in a protected, shallow coral-filled area, giving you a chance to practice skills like breathing control, buoyancy, mask clearing, and regulator recovery.
We loved the way the reviews highlight the instructors’ patience and clarity. One reviewer mentioned, “She explained everything very good and always made sure I understood.” That kind of personalized attention makes a huge difference when you’re learning a new skill and feeling a bit nervous.
Day 3: Reef Dives
The highlight is the final day, where a boat ride takes you out to the reefs of Cozumel’s marine park. Here, you’ll do two dives, reaching depths of up to 18 meters. This is where all the practice pays off, and you get to see some of the most vibrant underwater scenery in the Caribbean. Expect to encounter colorful corals, a variety of tropical fish, and perhaps even some larger marine creatures.
One enthusiastic reviewer shared, “Diving with Medusas Dive was great. I did my open water there and my instructor was Aida. She explained everything very well and always made sure I understood and felt safe.” That sense of security is crucial for beginners, and it’s great to see how consistently this is emphasized.
Daily Schedule
Each day involves about 5 hours of activity, balancing learning and practical experience without overloading you. The schedule is designed to be manageable, especially considering the condensed timeframe. You’ll likely find the days busy but rewarding, with enough time to relax and enjoy the surroundings after.
The Experience, Equipment, and Environment

The location in Cozumel adds a significant value to this course. Known for crystal-clear waters and abundant marine life, the reefs here are some of the best in the world.

This certification is valid globally, which means your underwater adventures don’t have to stop after Cozumel. Whether you’re planning to travel to other tropical destinations or revisit this Caribbean gem, you’ll be ready to go.
Cost and Value
At approximately $640.68 per person, the course isn’t cheap, but it’s a fair price for the comprehensive training and stunning reef access provided.
