Overview
The RAID Nitrox Certification in Havelock is a one-day specialty course for certified divers who want to learn how to safely use enriched air nitrox. Nitrox contains a higher percentage of oxygen than regular air and can provide longer no-decompression limits at suitable recreational depths when used correctly.
The course starts with RAID e-learning, which can be completed online before the course day. The learning covers oxygen physics, Maximum Operating Depth (MOD), no-decompression limits, oxygen exposure and the principles of planning nitrox dives.
During the practical session, you work with an oxygen analyser to check the actual gas mixture in a cylinder. You learn how to read the oxygen percentage, calculate the appropriate MOD, label the cylinder and document the gas mixture before a dive.
The course also includes dive-computer setup training. You learn how to enter the correct nitrox mix, understand the computer's oxygen exposure settings and use the computer for appropriate dive planning.
The course includes the RAID Enriched Air Nitrox certification, ISO-certified digital e-card, lifetime access to the RAID e-learning platform, oxygen analyser workshop, dive-computer configuration training and digital logbook entry..
Itinerary

- Review oxygen physics, MOD, NDL and oxygen exposure.
- Practise analysing a nitrox cylinder.
- Calculate and understand MOD for the gas mix.
- Learn correct cylinder labelling and documentation.
- Configure a dive computer for nitrox.
- Complete the course requirements.
- Receive RAID Nitrox digital certification.
- Optional nitrox dives can be added separately.
Difficulty and fitness
Suitable for recreational scuba diving and medically fit to dive.
- Rest well, stay hydrated and be ready for normal scuba-diving activity.
What to bring
- Complete the RAID e-learning before the course.
- Bring your Open Water certification.
- Review basic recreational dive planning.
- Bring your nitrox-capable dive computer if you have one.
- Stay hydrated and rested.
- Inform the instructor if your medical condition has changed since your last certification.
Essentials
- Open Water certification, personal dive computer if available, swimwear, water bottle, notebook/phone for e-learning and personal medicines.
Getting there
Report at the Frogman dive center in Govind Nagar at the confirmed course time.
Reach Havelock Island/Swaraj Dweep from Port Blair by an approved ferry or passenger boat service. From Havelock, reach the Frogman dive centre in Govind Nagar for the course.

Before you book
- Open Water certification is required.
- Course duration is 1 day.
- RAID e-learning should be completed before the practical session.
- Nitrox mixes covered by the vendor are 32–36% oxygen.
- 32% nitrox has a listed MOD of about 34 m; 36% has a listed MOD of about 28 m.
- Optional nitrox dives and tank fills cost extra.
- A nitrox-capable dive computer is recommended.
- No additional medical declaration is required beyond the Open Water medical requirements unless your health status has changed significantly.
- The certification teaches safe nitrox use; it does not increase your certified depth limit.
Safety notes
Always analyse the cylinder before diving. Use the correct gas percentage in your dive computer, understand the MOD and follow the planned depth limits. Nitrox does not permit deeper diving; increased oxygen concentration can reduce the maximum operating depth.
