Nitrox Course in Subic Bay, Philippines

Nitrox certification is a must-have for passionate scuba divers! My nitrox course in Subic Bay, Philippines, will supercharge your underwater exploration. Learn why every experienced diver chooses to certify as a Nitrox Diver!

What is Nitox?

Nitrox, also known as Enriched-Air Nitrox or EANx, is a breathing gas mixture used by scuba divers. Nitrox is made by adding a greater percentage of oxygen, which lowers the proportion of nitrogen that the diver breathes. Breathing less nitrogen means you absorb less nitrogen into your body. Nitrogen absorption is a major factor that limits the time that we can dive at recreational depths.

Why is nitrox certification valuable for scuba divers?

Nitrox has three huge benefits for scuba divers:

  • Longer bottom times!
  • Less risk of DCS on a given dive!
  • Reduced post-dive fatigue!

What do you learn on the nitrox course?

The RAID Nitrox course teaches you about dive planning for Nitrox gas mixes (up to 40%), gas analysis, and cylinder labeling procedures for cylinders. You will also gain an in-depth understanding of oxygen exposure limits, hazards, and contingencies.

The Nitrox course is designed to extend your knowledge and skills in the use of oxygen-enriched gases for recreational diving and is highly recommended before you progress to Advanced 35 and Deep 40 training. This course can be combined with other RAID courses.
