2 Days Class: SDI Open Water Diver Certification in Cancun

A’HA Scuba Diving should be everyone’s first choice when looking for a dive shop in Cancún—especially for Open Water certification. From the very start, Marin and Carolina went above and beyond to make sure my experience was safe, smooth, and unforgettable. On our first dive day, the port was closed due to wind, but instead of canceling or cutting corners, they immediately adapted and took us to dive the cenotes, which turned out to be an incredible experience. The flexibility, professionalism, and effort they put into accommodating the situation really set them apart. On the second day, we were able to dive the Cancún reef, and it was absolutely beautiful—clear water, vibrant marine life, and a perfect environment for open water dives. Everything was well organized, calm, and never rushed. Marin is an exceptional instructor—extremely knowledgeable, patient, and confident without ever being intimidating. As this was my first open water dives, feeling comfortable and safe was critical, and Marin made sure of that every step of the way. He explains things clearly, watches closely underwater, and genuinely cares about his divers’ success and confidence. You can tell this is a shop that truly loves what they do. The equipment was in great shape, the briefings were thorough, and the overall vibe was relaxed but highly professional. If you’re considering getting certified, doing cenote dives, or exploring the Cancún reef, do not hesitate—this is the place to go. I couldn’t have asked for a better introduction to open water diving, and I would dive with Marin and Carolina again in a heartbeat. Highly, highly recommended. 🌊🤿

My daughter (15) and I signed up with Ah Ha for our first diving experience, to get our SDI Open Water certification while on vacation in Cancun. We didn’t know exactly what to expect, but Timoteo and Carolina were absolutely amazing to work with! They supported us for two months before the trip as we worked on the online course and exam, and then as we arrived in Cancun with answering all of our questions. Their location is really easy to get to via public busses or Ubers, and after finishing the skills testing in the pool you just walk a few short steps to board the boat. During the course it was clear how much the ocean, reefs and diving mean to both of them, we loved practicing our Spanish with them and they both spoke great English also. They were very patient with us and made sure we felt safe and confident at every step of the process. I had a small personal issue during the course and they went above and beyond to help me work around it and stay on pace to complete the requirements and obtain my certification. During our live dives with Timoteo we saw hundreds of fish, nurse sharks, crabs, lobsters, rays, sea turtles and eels, so much life under the ocean around the beautiful reefs. The equipment was all clean, sized correctly for us and plenty of spares in case any issues came up. In the end, we could not have asked for more, Timoteo and Carolina were just THE BEST and we can’t wait to return and dive with them again soon.

It is the second time I have attended an activity with them and I definitely recommend them. Marin, our instructor was very friendly and professional the entire time, plus he takes incredible photos!! I will definitely return soon.

I did the open water certification with Marin and he is a great teacher. I highly recommend him. He took us to such beautiful places to dive. Would definitely go diving with him again. Everything was so well organized by his wife

Carolina and Marin are the perfect partners for this job! Caroline initially helped me with all the paperwork, online eLearning, and rescheduling due to the weather. Marin was very thorough in every step for your preparation for the open water dives (4). The assembly of the gear, details of what to do in the water, and made you practice everything in the pool first. It's everything in the eLearning and more, especially provided more info on survival skills. I wasn't nervous at all when it comes to open water ocean dive in the 1st day afternoon, and that is all because of Marin. He made me assemble the gears myself as part of the course, and I made a rookie mistake already. This shows everything needs practice. The open water dives are amazing, besides the coral reefs, he would practice communication under water with you, and test your skills again in the open water. Marin is made sure you are always next to him and check on your regularly. When water floods your mask, or regulator, or removing regulator from your mouth...think what Marin has taught you in the pool, and repeat it...the only difference is you are 30-55 feet in the ocean. The open water dives is a full boat, therefore don't worry...you are in good hands, and other divers will share their experiences with you including their best dives, locations, different adventures. BTW, signing up today for tomorrow won't work. eLearning takes time to complete (16 chapters and testing). It took me 3 days in between work to complete it. I wanted to do this 20 years ago, and only got to complete now. The best part of attaining the SDI Open Water Diver Certificate is you have the opportunity to dive around the world, recreational dives at the moment. I want to complete the advance course if possible, and I would come back to Marin and Caroline should the time and place permits!

THE TEAM TO DIVE WITH ! Divers or future divers, I strongly recommend A’ Ha’ as your dive center in Cancun. Marin is a very experienced dive master, his recommendations are key, he knows the area perfectly, he has multiple dive zone options and you can go out every day to different Spots as fascinating as the reefs around Tulum or cenotes for more or less experienced people. Caro is super efficient, gives you all the necessary information and quote very formally. Professional, reliable, no surprises and more than fair prices. I got my OPEN WATER certificate with them and they made it very easy. The sea was very complicated we made a first dive there. And we complete with a cenote to do the navigation and thus have an additional and different spot. You'll be surprised if you haven't tried them. I'll repeat.

I can only join all reviews - great people and 5 star service! Done my certificate at A'HA, reef and cenotes diving. Experience I will remember all my life. Would highly recommed these guys as your instructor or diving master. Thanks again and hope to see you again🤗✌

It was so much fun to make that course! Beginning with Carolina who perfectly helped me out before getting to Mexico with all the documents I needed, how to get to the hotel where the course started and much more. She welcomed me with a big smile when I got there. Thank you! Now to Timoteo Marin: He writes about himself that he's a passionate diver. He's not only that but also a very good teacher! He patiently taught me everything I need to know according to the SDI standards. I could feel his passion for scuba diving and he explained a lot to make sure I get a deep understanding of how things work under water. When we were diving I could see how he interacted with nature under water: calm, respectful, absolutely professional, and always having an eye on me. I already miss these guys and Mexico. I had a really great time.

The teacher was very knowledgeable and professional! I absolutely had a wounded time learning from him. I would recommend this with all my heart. Also he went above and beyond and not only recommend a nice restaurant but also dropped me of there for free without expecting anything in return. He has integrity on make sure you lean every thing by the book!
