The TDI Cavern Diver course is your first serious step into overhead environments. Based on the official TDI standards, I have designed this experience to challenge your current limits and transform you into a more disciplined, technical, and aware diver.
In this course, we don't just "go for a dive." We train. I will teach you the unique hazards associated with caverns—such as silting, entanglement, and disorientation—and, more importantly, how to prevent them through superior technique.
What We Will Master?
Equipment Redundancy: Understanding why we carry backup lights and specialized gear configurations.
The Continuous Guideline: I will train you on the art of reel handling, tie-offs, and following a line in zero-visibility simulations (touch-contact).
Propulsion & Environmental Awareness: Mastering the Modified Frog Kick and Anti-Silt techniques to protect the fragile cavern environment.
Gas Management: Strict adherence to the Rule of Thirds and stress management in overhead settings.
I will personally guide you through the rigorous curriculum required by TDI.

Please Note: For the TDI Cavern Diver course, I strongly recommend that you bring and use your own equipment. At this level of technical training, being intimately familiar with your gear's fit and function is key to your performance and safety.
If you do not own your equipment yet, high-quality technical gear is available for rent upon request.
❓ FAQ – Everything You Need to Know
In cavern diving, your equipment is your life-support system in an overhead environment. Using your own gear ensures you know exactly where everything is and how it reacts, which allows you to focus 100% on the new skills I will be teaching you.
The course lasts a minimum of 5 days. Given the intensity and the level of skill required, I do not rush this process. My goal is to ensure you leave with the mastery necessary for cave exploration.
The TDI Cavern course is demanding. To ensure safety and progress, you need a solid foundation in deep diving, navigation, and technical principles before we ever enter the overhead environment.
Yes. Experience matters. Having at least 50 dives ensures you have the comfort and air management skills needed to focus on complex tasks like line handling and emergency drills without being distracted by basic buoyancy.
I can help you get there. We can schedule these preparatory courses prior to your Cavern training. Contact me to design a long-term training plan that fits your goals.
You're welcome to bring your own underwater camera to capture memories! GoPro rental is also available subject to availability. Please note that photography policies vary by location — while open water diving allows full camera freedom, some cenotes may have restrictions or additional fees. I'll inform you of specific policies for each dive site.

I had a great experience diving with Alan and Jorge. We went to Casa Cenote for my refresher dive and later continued to Cenote dos ojos. It was a wonderful experience and I always felt well taken care of.
I would definitely come back to do more dives with you and can highly recommend going with them 😊

We shared four epic dives with Alan both at the cenotes and out from Playa del Carmen. Well organised, kind, great snacks, and very professional. Perfect mix of fun and dive etiquette. 100% recommend!

We went on 2 dives in a small group of three. Hairo was really nice and funny, and we had a great time! He told us about the Cenotes, the alligators, and much more in great detail. I would love to go diving with him again sometime. Cheers!

I dived with Alan in Cenote Dos Ojos and had an absolutely amazing experience. From start to finish, I felt completely safe and confident underwater. Alan is not only a highly skilled and professional instructor, but also someone with a great vibe — calm, positive, and genuinely kind. He creates an atmosphere of trust and enjoyment that makes the dive even more special. I couldn’t have asked for a better guide for my first cenote dive. Highly recommended.

This is a geat company. We had two cenote dives on our vacation. Alan was super patient and safety conscious. We appreciate how the day flowed. We also appreciate the complimentary snacks. Who knew spicy peanuts would taste so good?

👌Gorąco polecam odkrycie przepięknych cenotes z Alanem i jego teamem.
Alan jest profesjonalnym i super sympatycznym instruktorem i organizatorem, i współpracuje ze wspaniałymi przewodnikami. Gwarancja błyskawicznych odpowiedzi i organizacji. Zrobiłam z nim kurs sidemount i kilka dni nurkowania w różnych cenotes. Jeden piękniejszy od drugiego… 😍

Updating as I've dove with Alan now two years in a row. I've dove in quite a few locations around the world, usually renting equipment, and seen the good and bad of dive guides and shops. From my personal perspective: ALAN IS ONE OF THE BEST!! He is super friendly, carries quality rental gear, puts safety first, and is a great guide underwater. I can only highly recommend him for anyone diving the cenotes.
Original review (Jan 2025)
I stopped by in Tulum for a day of diving and found Alan via a Google search. He was a wonderful guide and person and I really enjoyed the day with him. Would definitely recommend his services!

We had an amazing experience with Allan, taking us to amazing dive sites and being very flexible with our demands. Communication on WhatsApp was very easy and he gave us great advice to pick the right Cenotes, and gave us amazing brief before each. We almost never saw other divers underwater thanks to perfect scheduling. He was very friendly, professional, had great quality equipment, never hurried us encouraging us to enjoy the scenery of the Cenotes before changing dive site, and on top gave us great recos to enjoy our stay in Tulum. One of my best experiences in 100+ dives.

Wir haben die Tauchschule über Google gefunden und eine Nachricht geschickt. Der Kontakt mit Alan war super professionell und sehr zügig. Wir haben zwei Dives gebucht und hatten einen privaten Dive. Nur meine Freundin und ich mit unserem Guide Jorge. Er war wirklich super nett und sehr erfahren was das Zenoten und Höhlentauchen angeht. Zuerst waren wir bei der Angelita Cenote und er hat uns alles sehr ausführlich erklärt, was uns Sicherheit bei diesen dive gegeben hat. Beim zweiten Tauchgang sind wir mit dem Auto zur zweiten Cenote - Carwash gefahren. Ein Shallow Dive mit unglaublich klarem Wasser. Wirklich richtig schön! Vielen Dank für die zwei unvergesslichen Tauchgänge 🤩🙏🏼
