Why nitrox gives you more time
Less nitrogen means slower nitrogen loading. You learn what that does to no-decompression limits and why the second and third dives of the day benefit most.

The course
Enriched Air Nitrox is the most popular specialty in the world for a boring, beautiful reason: it simply gives you more diving. Less nitrogen in your tank means more allowed bottom time, especially on the 15 to 25 m reef profiles you actually dive on holiday.
The course is one relaxed day. You learn why nitrox works, where its limits are, and the two skills that matter for the rest of your diving life: analysing a cylinder yourself and setting your computer for the mix. We do the analysis drills on real tanks on our boat, not on a whiteboard.
The practical difference is easy to feel. On a repetitive two-dive day, an air diver is often pushed shallow or short on the second dive. A nitrox diver just keeps diving. Book it as a standalone day or bolt it onto any course or dive package.
Skills
Less nitrogen means slower nitrogen loading. You learn what that does to no-decompression limits and why the second and third dives of the day benefit most.
More oxygen has a depth limit. You learn to calculate the maximum operating depth for any mix and why divers never guess it.
The core habit of the course: put the analyser on the valve, verify the mix, label the tank, log it. Thirty seconds that professionals never skip.
Enter the oxygen percentage, check the depth limit, dive the plan. We set up your computer together until it is second nature.
Where this takes you next
Nitrox knowledge plus deep training is the classic combination for serious Red Sea reef and wreck weeks.

Nitrox-Kurs an einem Tag zwischen den Tauchgängen gemacht. Endlich verstehe ich MOD und Analyse wirklich, statt nur zu nicken. Ab dem zweiten Tauchtag deutlich längere Grundzeiten. Bester Ein-Tages-Kurs überhaupt.

Did the nitrox course on day one of our week and dived enriched air the rest of the trip. The analyser practice on real tanks was great, not just theory. Second dives stopped feeling rushed. Should have done this years ago.

Nitrox kurz za jeden den, výborně zorganizovaný. Analýza láhve, nastavení počítače, plánování, všechno prakticky na lodi. Instruktor mluvil srozumitelnou angličtinou a měl trpělivost s dotazy. Doporučuji každému.

Corso nitrox veloce e ben fatto. Teoria online, poi analisi delle bombole in barca e subito due immersioni EAN32. Tempi di fondo molto più lunghi sulla seconda immersione. Unico neo: avrei voluto più esercizi di pianificazione.

Good to know
Used within its limits, nitrox reduces nitrogen loading, which is why many divers feel fresher after repetitive dives. It adds one rule of its own: an oxygen depth limit you must calculate and respect. The course exists to make that rule automatic.
PADI does not require dives for this specialty, so the certification can be done in a day of theory and practical gas analysis. Most of our students add an afternoon of nitrox dives the same day to feel the difference immediately.
One day. eLearning takes 2 to 4 hours, then we do cylinder analysis, computer setup and planning exercises on the boat. You can combine it with a normal diving day without losing dives.
No. We provide nitrox-capable computers during the course and teach you the setup on whatever model you will actually dive with. If you own a computer, bring it and we configure yours.
If you dive two or more times a day, yes without question. The certification is lifetime, the course costs €215, and it pays itself back in bottom time on the very first diving day. It is the best value card in the PADI system.
The water is 28°C, the visibility is over 30 m, and a boat with your name on it leaves tomorrow at 8 AM.
