Extend your diving limits and become a PADI Nitrox diver

Would you like to stay longer when your dive computer tells you its time to finish your dive?

Would you like to get back into the water sooner after a dive?

If the answer to both of these questions is yes than you need to dive on Enriched Air or Nitrox as it is commonly known as.

What is Enriched Air Diver (Nitrox) Diving

By increasing the percentage of oxygen in the air we breathe, we can consume less nitrogen. This gives you longer no decompression times, especially so on repetitive dives.

If staying underwater longer and spending less time on the surface sounds like your sort of thing then do not waste any more of your time diving on a gas mixture of 21%.

Learn to dive on Enriched Air (Nitrox) and extend your level of diver training.

PADI Enriched Air Diver Specialty Course Information:

Orientation & Knowledge Development

We start the PADI Enriched Air diver specialty diving course with an Orientation that includes completion of paperwork and the PADI Medical statement.

The PADI Enriched Air diver specialty course consists of 2 training dives that you will make at dive sites around Koh Tao.

There is an Enriched Air diver video to watch and a specialty manual to read, along with a 12 question open book knowledge review to complete, which your dive instructor will guide you through and review.

Review the Enriched Air Diver Specialty Course Materials

The Instructor led knowledge development is conducted prior to your two Nitrox dives, so if you want to dive in the morning, we complete the knowledge development the previous afternoon.

Once you and your Instructor are happy you understand everything there is a final exam to complete and then we will analyze your cylinders in preparation for the dives at Koh Tao dive sites.

Some of the subjects you will cover include:

  • The benefits of diving on Enriched Air
  • The recommendations for using equipment with enriched air
  • Air filling procedures, cylinder markings & analyzing
  • Planning Enriched Air dives using a dive computer
  • Oxygen partial pressures, maximum and contingency depth limits and hazards of exceeding these
  • Signs and symptoms of oxygen toxicity

PADI Enriched Air Diver Practical Assessments

Practical Assessment #1

During the first practical assessment you will be shown how to use an oxygen analyzer to determine the oxygen content in an enriched air blend.

Your Dive Instructor will also show you how to verify cylinder content data and sign the fill log. By the end of the session, you will be able to demonstrate both.

Practical Assessment #2

During the second practical assessment you will be asked to demonstrate the procedures for obtaining an enriched fill and renting an enriched air cylinder from an enriched air fill station.

Open Water training – there are 2 Enriched Air dives to complete.

Enriched Air training dives 1 & 2

During Enriched Air training dives 1 & 2 you will execute two dives within the no stop limits with your Instructor, establishing your maximum depth and oxygen exposure limits during pre-dive planning.

You will also be expected to use your dive computer to plan these dives. At the end of both dives you will perform a safety stop at 5 metres /15 feet.

Congratulations. You are now a PADI Enriched Air Specialty Diver.

Frequently Asked Questions

What will I learn on the Enriched Air Diver (Nitrox) Specialty course Koh Tao?

You will learn about the benefits of using enriched air in scuba diving.

You will learn about the oxygen partial pressure in your gas blend and how to calculate your maximum operating depth to stay within the oxygen exposure limits.

We will teach you how to obtain and analyze a nitrox cylinder using an oxygen analyzer.

During the dives (or dive simulation) we will help you set up the dive computer for your gas blend.

How long is the Enriched Air Diver (Nitrox) Specialty course for Koh Tao?

The Enriched Air Diver Specialty course typically takes 1 day to complete on Koh Tao, however, there are 2 different ways you can get certified as a PADI Enriched Air Diver.

With option one you take the course as a stand-alone course and you will start with the video and knowledge review, before taking the Enriched Air Diver exam.

You will then analyze your enriched air tanks and use them on your 2 dives that are included.

The second option is a theory-only option. By PADI Standards it is not required to do any dives, but instead do a dive simulation, analyzing tanks and setting up a dive computer.

It is possible to combine this option with any other PADI course, thus giving you 2 certifications.

In that case, you will get to use nitrox cylinders on some of the dives of your other courses, but it does not give you any additional dives.

What is the cost of the Enriched Air Diver Specialty course Koh Tao?

The cost of the PADI Enriched Air Diver Specialty is THB 7,500 (2 dives) or THB 5,900 (no dives, theory only).

Included in this price are all course materials, dive equipment rental (including dive computer), instructor fees, boat trips and insurance.

Food and accommodation are not included. However, you can contact us to find out about accommodation options. We have AC rooms available at discounted rates when taking a diving course with us.

Ex-students will enjoy a 10% discount on the course price.

How many dives is the Nitrox Specialty course Koh Tao?

The amount of dives depends on the course option you choose: stand-alone, theory only or a combination with other PADI courses or specialties, such as PADI Deep specialty.

In the stand-alone option, you get 2 enriched air dives included. In the theory only option there are no dives, only dive simulations.

If you decide to combine the Enriched Air Diver specialty with another course or specialty, you will get to use enriched air on 2 of the dives of your other course.

However, it does not give you additional dives beyond what is required for your primary course or specialty.

Send us a message if you would like to find out more.

What is the difference between Air and Enriched Air Nitrox when diving?

Enriched Air contains a higher oxygen percentage than normal Air. Normal air has about 21% oxygen and 79% nitrogen.

With Enriched Air Nitrox the oxygen percentage will be higher and it can be anything between 21% and 40%.

By replacing some of the nitrogen in your cylinder with oxygen it will allow you to stay at depth for longer because of the increased no stop time (no decompression limit).

This is especially beneficial when making multiple deep dives in a day.
