PADI Enriched Air (Nitrox) Course
Koh Tao Thailand

Intro | PADI Enriched Air Diver Specialty in Koh Tao

Ever wished you could stay down longer but had to end your dive due to your No Decompression Limit? The PADI Enriched Air Specialty will enable you to extend your dive time.

Enriched air diving (sometimes referred to as EANX or Nitrox diving) allows a diver to stay submerged for longer by reducing the amount of nitrogen in our breathing cylinder, replacing it with oxygen. Nitrogen absorption determines our no-decompression limits, so by reducing the amount of nitrogen our body absorbs we can extend our bottom time at depth.

But nothing comes for free! Increasing the oxygen percentage of our breathing gas creates an elevated risk of oxygen toxicity, therefore additional planning steps and procedures are needed to safely enjoy the benefits of diving with nitrox.

The PADI Nitrox course certifies you to safely dive with nitrox blends containing up to 40% oxygen, to extend your bottom time and/or enhance the safety of your dives.

Plus the course gives us the opportunity to make two deep dives on nitrox, enjoying extra dive time as we explore dive sites off Koh Tao.

(& if you are getting really serious about diving, enriched air diver training is a prerequisite for technical diver training).

PADI Nitrox Course: Schedule

We’re flexible with the schedule of the nitrox training and can adapt it to fit with your travel plans. Usually the course proceeds as follows:

Day 1: Theory, nitrox analyzing and dive planning
You’ll meet your instructor and begin by covering some nitrox diving theory, learning about partial pressures of gases, special considerations for equipment suitability when using nitrox plus how to safely manage oxygen exposure.

You will learn and practice how to analyze the oxygen content of a cylinder and become familiar with procedures for obtaining nitrox from a gas blending facility. Finally we’ll draw up a dive plan for our two dives on nitrox the following day.

Day 2: Nitrox Dives off Koh Tao
With our dive plan complete, tanks analyzed and correctly marked up we’ll board the Simple Life boat and head out for two dives.

On route to the dive site you will set your dive computer to the chosen blend of nitrox. Your instructor will cover dive computer operation with nitrox, and we’ll have a thorough briefing covering how the dives will be executed.

For the two dives, provided conditions permit we’ll most likely visit two of Koh Tao’s more challenging dive sites such as the Chumphon Pinnacles, Southwest or the HTMS Sattakut wreck. Diving with an enriched air blend in such depth ranges you’ll really get to see the benefits of extended bottom time.

On return to the dive shop you’ll then be certified as a PADI Enriched Air Diver.
