Enriched Air (Nitrox) by SDI
What is Nitrox?
More Oxygen: Nitrox is a breathing gas with a higher oxygen content than regular air. By adjusting the oxygen levels, we can extend our bottom time and reduce nitrogen absorption.
Safer Decompression: Nitrox reduces the risk of decompression sickness (the bends) by allowing for longer no-decompression limits.
Benefits of Nitrox Diving
Extended Bottom Time: With Nitrox, you can stay underwater longer during repetitive dives. Explore wrecks, reefs, and marine life without rushing.
Less Fatigue: Reduced nitrogen exposure means less fatigue after diving. You’ll feel more energized for subsequent dives.
Shallower Profiles: Nitrox allows for shallower profiles, minimizing nitrogen buildup and enhancing safety.
extended underwater adventures
Enriched Air
Welcome to Enriched Air (Nitrox) diving! As your personal dive instructor, I’m excited to introduce you to the world of extended underwater adventures.
Considerations
Oxygen Exposure:
While Nitrox is safe within recreational limits, we’ll discuss the maximum depth and oxygen percentage for your dives.
Complete Equipment:
No worries—I provide all the necessary Nitrox-compatible equipment, including tanks and analyzers.
Certification:
If you’re not Nitrox-certified yet, let’s get you trained! It’s a straightforward course that opens up new diving possibilities.
Different Configuration: Sidemount diving involves using one or two cylinders mounted on your sides instead of the traditional back-mounted setup.
Advantages: Sidemount offers several advantages, including better streamlining, easier cylinder handling, and increased gas redundancy.
Why Choose Sidemount?
Enhanced Buoyancy: Sidemount allows for better balance and trim underwater. You’ll feel more in control and comfortable.
Extended Bottom Time: With redundant gas supplies, you can explore deeper and stay down longer.
Versatility: Sidemount is ideal for cave diving, wreck exploration, and tight spaces.

Cenote 다이빙 추천합니다!! 첫 동굴 다이빙이었는데 친근한 분위기에 재밌고 안전하게 잘 즐겼어요!! 동굴 속 멋진 모습을 찬찬히 보여준 Alan 고맙습니당 다음에 또 오면 Alan이랑 산호 다이빙도 가고 싶네요!!!

Expérience de plongée inoubliable avec Alan et Diving Universe Tulum !
Alan a été absolument merveilleux durant notre formation de plongée. Très patient, il a pris le temps de tout nous expliquer en détail, ce qui nous a permis d’être à l’aise et en confiance dès le début. Il parle très bien anglais, ce qui facilite énormément la communication.
Les spots de plongée étaient magnifiques, une vraie découverte à couper le souffle ! De plus, l’expérience s’est terminée sur une belle note avec un repas ensemble au restaurant le dernier soir, un super moment de partage.
Un conseil : lisez bien la théorie qu’il remet au début pour arriver préparé et maximiser votre apprentissage. Cela aide énormément pour l’examen et pour mieux comprendre tout ce qui est enseigné en pratique.
Je recommande vivement Diving Universe Tulum et Alan pour une expérience de plongée exceptionnelle !

We had an amazing experience diving in the cenotes with Alan! As first-time cenote divers, we were a bit nervous, but Alan, the owner and our instructor, made us feel completely safe and comfortable. He took the time to explain everything clearly, adapted the dive to our needs and experience level, and ensured we felt confident throughout.
As a bonus, Alan also gave us some great recommendations for food and restaurants in the area, which we really appreciated. We highly recommend diving with him!

Allan is top class. We did amazing cenote dives. He is professional and really good about taking care of his divers. He gave us TONS of local information.
Cenote dives are very small and personal dives. Do yourself a favor and do it with this company.

My partner and I had the chance to squeeze in a day of diving while in tulum before a wedding. It did not disappoint! The cenotes are such a unique diving experience. We dive Angelita and Car Wash with Alan and had a blast. Alan was an amazing guide. Very knowledgeable, safe and fun to be around. He also took some great go pro videos of the two of us! When we come back for a proper diving trip in the area we would absolutely reach back out to Alan to guide us again.

Such a fantastic day with Peggy! This was my first official dive after certification and it was wonderful. I was nervous but Peggy put me at ease, helped me figure out my buoyancy and showed me the most beautiful places! We dove in Casa Cenote and Cenote Car Wash. Car Wash was unreal! I would definitely recommend Peggy and Alan and can’t wait for my next trip back to Tulum to dive with them.

Wauw! Wat een fantastische ervaring heeft Alan ons bezorgd! Zijn communicatie is zeer prettig en helder. Hij beoordeelde samen met ons in welke cenotes we het beste konden duiken. Na een surrealistische duik in Cenote Angelita waar we door verschillende lagen heen doken rondom een eiland onderwater, gingen we naar Cenote DreamGate. Een ervaring die we nooit zullen vergeten. Waanzinnige formaties en een kronkelende route langs stalagmieten en stalactieten. Het materiaal van Alan waar we mee doken was van goede kwaliteit en goed onderhouden. Ik kan het niet genoeg aanraden! Wat was dit super!! Enorm bedankt Alan!🙌🏼

Alan was super professional with excellent equipment. We felt very safe diving with him because he clearly knows his trade, and he never rushed. He was a very pleasant guy to spend the day with: friendly, relaxed, and attentive.
We did a refresher dive with him in an open cenote passing through beautiful mangrove and limestone caves with stunning scenery. Next we did a deeper cave dive in another cenote that was also incredible. Both had underwater wildlife as well as interesting cave formations and attractions to see.
I recommend him 100%
