Extending your bottom time is crucial for serious exploration. However, doing so requires precise knowledge of gas physiology. As your instructor, I don't just teach you the theory; I ensure you understand the practical application of diving with Enriched Air.
Specifically, my tailored instruction focuses on three key pillars:
First, we master the physics. You will learn exactly how higher oxygen percentages affect your depth limits and safety margins.
Furthermore, I emphasize practical skills. Instead of generic drills, we focus on hands-on cylinder analysis and computer configuration.
Finally, we plan for safety. Because oxygen toxicity is a real risk, I personally guide you through advanced dive planning to mitigate hazards.
Who is this course for?
Although this is a foundational certification, it is essential for anyone looking to maximize their time underwater. Whether you are exploring local Cenotes or planning for deeper technical training later, this course sets the standard. Consequently, you will emerge as a more confident and knowledgeable diver.

Thank you Alan, for a fanstatic Cenote expierience! Alan is a great diver, a super photographer and a truly excellent guide. Diving the Cenotes was my first taste of overhead environments and under Alan's professional guidance, I felt totally safe. His local Cenote knowledge was very impressive, as was his tips about local places to eat and drink. It is my hope to return to Tulum and dive with Alan again. Highly recommended !

Allan was a great tour guide n dive instructor. Always cheekily chuckling. We had a great time. He got us an awesome burrito after the dives on the first day and went out for a beer with us after the final dive. No nonsense. He expected us to know what we were doing and we were in the water quicker and stayed for longer. It’s another planet down in those caves I can’t wait to go back. Recommend

It took me a while to find the right dive centre, as we were coming all the way from Australia to dive the cenotes and only had a few days. Allan absolutely blew me away with his patience, answering all my questions over several weeks and even helping us plan our trip so we could get the best visibility and light rays at each location. He went above and beyond our expectations. It was important for us to find the right fit, as we were spending most of our trip diving with the same person. Allan recommended amazing local places to eat, shared so much about the nature and cenotes, and even brought us the most delicious tacos on our first day. As a local, he really knows his stuff. We felt completely safe with him the entire time. I can’t recommend Allan highly enough, and I’ll definitely be recommending him to all my friends. My advice when choosing a dive guide: speak directly with them first—you’ll know if they’re the right fit. Hopefully we’ll get to dive with Allan again one day. Thank you so much for giving us the best few days of our trip! We were also incredibly lucky that Allan’s freediver friend took photos of us in El Pit. It was such an unexpected bonus and just another example of Allan going above and beyond. We absolutely loved every minute of it!

I had an amazing experience with this company. From start to finish, the staff was professional, knowledgeable, and incredibly welcoming. They made my husband and I feel safe and comfortable. The equipment was well-maintained, the instruction was clear, and the dive itself in the cenotes was unforgettable. You can tell they truly care about creating a fun, safe, and memorable experience for every guest. I would highly recommend them to anyone looking for a great scuba diving adventure!

This was my first trip to Tulum and my first time cenote diving. On my first day, I dived with Jorge at Dos Ojos and The Pit, and on my second day, I dived with Alan at Dream Gate and Angelita. Both instructors were not only very professional and safe guides, but also very friendly and helpful in sharing local travel information. I'm very grateful to them for making my trip to Tulum such a wonderful experience. Highly recommended!

I’ve never been diving in a cenote before and there are a few operators providing dives to go there. When I tell you Alan provided the BEST experience, from helping with the theory to my nitrox, giving me recommendations for dinner to bringing the best mangos I’ve had in Mexico as a snack. The diving was incredible, I’ve never dived in freshwater so when we were getting water up Alan knew my weighting would be off and adjust this with a tester dive. Flawlessly professional whilst have the best personality and knowledge of the cenotes. If you are in tulum, drop him a message!

La communication en amont était excellente avec des réponses rapides et claires. Alan a rendu l’experience de plongée en cenote extraordinaire et très rassurante. En bonus, nous avons eu des explications intéressantes sur les cenotes et le Mexique.

Alan seems like a natural teacher - patient, clear, methodical, so that my teenage sons and I felt prepared each step of the way. Good vibes, tasty snacks, and a beautiful, special experience for us. Thank you Alan!
