Enriched Air Nitrox Diver training in Koh Lanta

The PADI Enriched Air Diver course in Koh Lanta is the most popular PADI Specialty with certified divers. From the age of 12, divers have the opportunity to register for this course, which can be done in a few hours at Apo Dhatu Divers. Otherwise, the course is usually completed without performing any dives, although there are optional open water dives. Keep reading for the top four reasons for this to be your next specialty.

Breathe less nitrogen when diving

The main advantage of using enriched air while diving is that you are exposed to less nitrogen. The higher the percentage of oxygen in the cylinder, the less nitrogen you breathe. You can use this phenomenon to your advantage in several ways; one of them is to extend your no-stop time, so you get longer dive times, especially when they are repetitive. Alternatively, you might prefer to continue diving within the limits of no-stop diving for air, but use the reduced nitrogen uptake to increase your personal diving safety margin.

The main objective of the PADI Enriched Air Nitrox training in Koh Lanta, is to learn the benefits and dangers of this gas in depth. That’s why, here in Koh Lanta, this formation is really interesting and totally appropriate, thanks to sites whose depths are totally in line with this gas.

Longer dive times

Typically, when using enriched air, divers get the mixes that have an oxygen content of 32% or 36%, which makes enriched air ideal for diving at lower depths. For example, when air diving to a depth of 18 meters using the PADI Recreational Dive Table, there is a maximum no-stop limit of 56 minutes for a single dive. For the same depth, but using an enriched air mixture with 32% oxygen content, you have a 95 minute no-stop limit at 18 meters. This means that, compared to air, you would have an additional 39 minutes of dive time for this profile. However, do not forget to control your instruments because you will always breathe the gas from your cylinder at the same rate.

Work towards further qualifications and learn to use your dive computer

During the Enriched Air Nitrox course in Koh Lanta, you can learn how to plan enriched air dives using tables or a dive computer. Currently, most divers use a dive computer with enriched air. If you’re thinking of buying your first dive computer, talk to us about completing the PADI Enriched Air Nitrox course at the same time, as it will improve your understanding of how your computer works. Likewise, if you have ambitions to one day become a PADI Divemaster, taking the PADI Enriched Air Nitrox course will help you understand the concepts that will allow you to better understand decompression theory and physiology. The great news is that you can link the PADI Enriched Air Nitrox course with any other PADI certification.

If you’re a PADI (Junior) Open Water Diver who is at least 12 years old, you can enroll in the PADI Enriched Air Diver Specialty course. Note that in some regions the minimum age is older than 12.

You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session, and two optional (or required) scuba dives, you’ll:

  • Discuss managing oxygen exposure.
  • Practice analyzing oxygen content in your scuba tank.
  • Set your dive computer for diving with enriched air nitrox.
