Dive at depth longer with the PADI Nitrox Course
The PADI Enriched Air Nitrox Course is the world’s most popular specialty course, and Malapascua is the perfect place to do it. More bottom time with thresher sharks, tiger sharks, pygmy seahorses, and wrecks.
Dive longer, feel better, get more from every tank.
Why Nitrox on Malapascua?
Enriched Air Nitrox (EANx) contains more oxygen and less nitrogen than regular air, typically 32% or 36% O2. Less nitrogen absorption means longer no-deco limits, shorter surface intervals, and less post-dive fatigue.
On Malapascua, the difference is dramatic:
- Monad Shoal (tiger sharks) sits at 22-25m. On air, average bottom time is 37 minutes. On Nitrox? Around 70 minutes. That is two dives for the price of one.
- Gato Island has a pygmy seahorse fan at 25m. Nitrox gives you the time to actually find them and tick off this bucket-list creature.
- Dona Marilyn and Tapilon wrecks are perfect for extended Nitrox profiles.
- Kalanggaman wall dives are also well suited for Nitrox at depth.
Many of our divers do every dive on Nitrox, taking advantage of our discount package prices.

Three ways to get Nitrox certified at TSD. All include PADI eLearning, your certification, and tuition from our experienced team of PADI Instructors. And did we mention… thresher shark dives?!!!
Course Overview
The Nitrox course has a small amount of reading and will not take up much of your holiday. Complete the theory in advance with PADI eLearning if you pre-book, so all that is left to do when you arrive is dive.
What you will learn:
- How to plan dives using enriched air
- How to analyse your tank’s oxygen content
- How to set your dive computer for Nitrox
- Managing oxygen exposure limits
- The real-world benefits and risks of diving with EANx
- What a compressor room looks like and see how we fill nitrox manually and with our membrane system.
The course has been simplified with computer use only. No more tables. Free computer rental included with all course dives.
Pro tip: Consider combining the Nitrox course with your Advanced Open Water or any of PADI’s Specialty Courses to save time and money. We offer special package pricing for course combos.
