Earning an Enriched Air Nitrox Certification

Independent study

PADI eLearning- You can fit scuba diving lessons into your hectic schedule easily with online learning. One can complete the independent study part of this diving course at their convenience. You can work at your own pace, online or offline, using a mobile device or a computer. Talk to the instructor for in-water training or whenever there is some doubt.

eLearning time commitment: 2-4 hours

At the dive shop

With your instructor- Once your independent study is finished, then you will be taught how to analyse a tank, fill out an enriched air log, and set your dive computer for nitrox. There are two optional dives as well.

  • Prerequisites: PADI Open Water Diver (or qualifying certification)
  • Total time commitment: 1-2 days
  • Minimum age: 12 years or older
  • Depth: 0

Medical requirements

A minimum level of health and fitness is required for scuba diving. In case you are suffering from any chronic health condition, or taking certain medications and/or had surgery recently, you will have to get written approval from a physician before diving. In order to avoid any confusion, you can simply download and review the Diver Medical Form to make sure that you will not require approval from a physician to dive. You should not ask your instructor, dive master, or dive shop staff for medical advice as they are not physicians. Only medical professionals can give medical clearance to dive if you do not have a minimum level of health and fitness. 

Prerequisites and minimum age

Minimum age: 12 years

Course prerequisite: Enrolment in Open Water Diver

Divers, who are 12 years or older, can earn a PADI Enriched Air Diver certification as a part of their PADI Open Water Diver course. For more details, you can talk to your instructor. 

Other costs and equipment

PADI Enriched Air (Nitrox) Diver certification requires both knowledge development as well as in-person training. 

  • The cost covers the knowledge development portion only when you buy the PADI eLearning course online.
  • An additional cost is involved in completing the practical training with a PADI Instructor. You can contact Aqua Nomads, a 5-star PADI facility in Havelock Island (Swaraj Dweep), for more information.

If you want to make the two optional dives but you do not own a set of scuba equipment, then you will need to rent it. 

In case you have your own scuba gear, then make sure that it can be used with nitrox. However, most modern dive equipment is compatible. The PADI dive shop or your instructor will help you if you don’t have the manuals of your equipment.

You will learn in your course that only certain scuba tanks can be filled with enriched air. You will be provided dedicated nitrox cylinders for your enriched air dives by your PADI dive shop. Your instructor will also provide an oxygen analyzer.

Time commitment

PADI eLearning: 2-4 hours

Entire course: 1-2 days

One can earn nitrox certification in just one day. All you have to do is complete the online course and fix a short practical session with your PADI instructor. The two dives are optional. A nitrox certification can be earned simultaneously with another course. After you have completed Enriched Air eLearning and the practical session with your instructor, you can use nitrox while completing dives for Peak Performance Buoyancy certification, Advanced Open Water Diver certification, etc.

After Enriched Air (Nitrox) Diver

If you are willing to learn how to stay underwater for an extended period, experience close-up animal encounters, and explore exclusive diving spots, then ask your PADI trainer about rebreather or technical diving.

Technical diving will allow you to dive beyond recreational ‘no stop’ limits. You can stay at a shallow depth for hours or dive beyond recreational dive limits. 

Rebreathers save and recycle your breathing gas. Thus, you can stay much longer under the water. Little to no bubbles are emitted by rebreathers. That’s why you can get closer to wildlife that otherwise may run away from the noisy bubbles of an open circuit system.
