SSI EAN32/40

Enriched Air Nitrox (EANx) replaces some of the nitrogen in standard air with additional oxygen. With less nitrogen entering your body, your no-decompression limits (NDLs) extend significantly — meaning more time underwater before you need to surface.

At 18 metres on standard air, your NDL is around 56 minutes. On EANx32 (32% oxygen), the same depth gives you roughly 95 minutes. The SSI Enriched Air Nitrox course is mostly theory, with no extra dives required, and it's the most popular specialty certification in recreational diving worldwide.

At FlyingFish: We stock EANx32 and EANx36 tank fills on-site. Upon certification you can start using Nitrox on the same day — on any fun dive or other course dive.

SSI Enriched Air Nitrox — what you'll learn

Oxygen ToxicityUnderstanding partial pressure of oxygen (PPO2), maximum operating depth (MOD) calculation, CNS oxygen toxicity symptoms and prevention.

Partial Pressure PhysicsHow gas mixtures behave under pressure — Dalton's Law applied to Nitrox planning. Calculating equivalent air depth (EAD) for NDL extension.

Nitrox Dive Tables and ComputersUsing EANx32 and EANx36 tables for NDL planning. Programming a dive computer (Aladin Sport) for Nitrox operation.

Gas Analysis with an O2 AnalyserHow to verify the oxygen percentage in your tank using an O2 analyser before every Nitrox dive. Required by SSI standards.

Equipment Considerations for NitroxWhich components require O2-compatibility above 40% oxygen. What 'O2-clean' means and why it matters above certain concentrations.

Nitrox Dive PlanningPlanning a multi-dive day using Nitrox — staggered MODs, surface intervals, combining air and Nitrox dives in one day.

The SSI EAN course has no required dives; it's a knowledge-based certification. That said, the gas analysis training is hands-on, with real O2 analysers and real Nitrox fills.

Who can take SSI Enriched Air Nitrox

SSI Open Water Diver or equivalent

Age 10 years or older

No additional dive experience required

No prior specialty training needed

This is one of the easiest specialties to get into. If you hold any Open Water certification, you're eligible.

Nitrox course — theory first, then straight to diving

The SSI Enriched Air Nitrox course needs no extra open water dives to certify, which makes it one of the quickest specialties to finish.

Same-day application: Complete the theory and gas analysis training in the morning, and you can dive Nitrox that afternoon — on a fun dive at Grandé Island or as part of another ongoing course. Our ScubaPro Aladin Sport computers are pre-programmed to accept Nitrox mixes up to 50% O2.

If you'd like to try Nitrox diving during your certification, we can add 1–2 optional Nitrox dives at Grandé Island on the same day as your theory session. Grandé Reef and Shelter Cove at 10–18m are great for a first Nitrox dive; you'll see the longer NDL on your computer straight away.

What's included in this course

Theory sessions on Nitrox physics and planning

Nitrox dive planning workshops

Gas analysis training with real O2 analyser

SSI Enriched Air Nitrox certification card

Not Included

Equipment rental for dives (can add optional dives)
Accommodation
Personal expenses

Certification: Your digital certification card is issued immediately upon successful completion. You are certified before you leave Goa and can dive anywhere in the world.

After your SSI Enriched Air Nitrox certification

Your EAN cert changes what you can do on every dive, right away:

Use EANx32 or EANx36 fills at FlyingFish and any SSI Nitrox centre worldwide

Significantly extended NDLs at typical recreational depths (18–30m)

Reduced nitrogen loading = less fatigue on repetitive dive days

Nitrox fills available right here at FlyingFish — use it from Day 1

Counts toward SSI Master Diver (4 specialties + rescue required)

Pairs perfectly with: SSI Advanced Open Water — do both in one trip and your 30m deep dives will have meaningfully better NDLs on Nitrox than on air.

Why take your course with FlyingFish in Goa

Here's what actually sets us apart, minus the marketing fluff.

ScubaPro gear, serviced on schedule

Pro-grade gear serviced every 100 dives or 6 months, not when it fails. MK25/S620 regulator, Hydros Pro BCD, Aladin Sport dive computer. You train on the same kit our working instructors use.

Maximum 4:1 diver-to-instructor ratio

Your instructor always knows where you are underwater. No crowded groups. If a skill needs more practice, you get the time, not whatever's left over after 8 other students.

Both SSI and PADI certifications at one centre

We teach both agencies at the same location, so you can pick the certification that fits your future dive plans. You get honest advice, not a push toward whichever we sell more of.

A proper base at 5-star Novotel Candolim

Proper briefing rooms, clean rinsing stations, a structured course schedule. The difference between a real dive school and a beach shack matters when you're doing a multi-day certification course.

EANx32 and EANx36 fills on-site, use Nitrox the same day

We stock Nitrox fills at the dive centre, so you don't have to wait until your next trip to use your new qualification. Do the theory in the morning, dive Nitrox that afternoon at Grandé Island. The Aladin Sport computers on all our rental kit handle Nitrox programming out of the box.

Frequently Asked Questions

No — the SSI Enriched Air Nitrox certification is primarily theory-based. You complete academic sessions, dive planning exercises, and gas analysis training, but no additional open water dives are required for the certification itself. If you want to practice Nitrox diving, we can add optional dives to your schedule on the same day.

EANx32 has 32% oxygen (standard air is 21%). EANx36 has 36% oxygen. The higher the oxygen percentage, the more extended your NDLs at shallower depths — but the lower your maximum operating depth (MOD). EANx32 can be used to a MOD of about 34m. EANx36 to about 28m. The course teaches you to calculate and respect these limits.

On standard air at 18m, your NDL is approximately 56 minutes. On EANx32 at the same depth, your NDL extends to approximately 95 minutes — nearly double. At 12m (a common training depth), EANx32 gives essentially unlimited NDL for recreational dive durations. The difference becomes most significant on repetitive dive days.

Oxygen toxicity is real but easily avoided within recreational diving limits. The SSI EAN course teaches you exactly where those limits are (maximum PPO2 of 1.4 bar for diving, 1.6 bar absolute limit) and how to stay well within them using gas analysis and proper dive planning. Within these limits, Nitrox is safer than air from a decompression perspective.

Yes. Enriched Air Nitrox certifications from SSI and PADI are cross-recognised — PADI centres will fill Nitrox for SSI Nitrox certified divers and vice versa. The key is showing your certification card and performing a gas analysis before each dive, which is universal procedure regardless of agency.

Yes — the theory sessions take approximately half a day. We can schedule it on the morning of your first full day in Goa. If you have already done other diving with us and want to add Nitrox to your trip, we can often fit the theory session on a non-diving afternoon.

My wife and I had an amazing experience with Flying Fish Scuba School and instructor Sunny. Despite her never having been in a swimming pool, my wife completed her dive course successfully thanks to their incredible support and professionalism. If you want quality instruction and genuine care—not scams—this is the place. 100% worth it!

 Trustindex verifies that the original source of the review is Google. you are looking for scuba diving in Goa, you’ve likely noticed dozens of operators offering "5-in-1" water sports combos at low prices. As a tourist, I was skeptical of these "scammy" setups. I decided to go with FlyingFish Scuba School (based at the Novotel Resort) based on the review It was definitely the right call and I can easily say it's the BEST scuba diving experience in Goa.

The Training & Team
The experience started with a thorough pool session, which was incredibly helpful for getting comfortable with the gear and breathing techniques before heading into open water. A huge shoutout to Mr. Dinesh and Ms. Maitri, they were phenomenal. Both were professional, friendly, and reliable, which is exactly what you want when you’re 10-12 meters underwater.

The Dive (Scuba 40)
I opted for the 40-minute dive. The marine life was beautiful; I saw a variety of fish and healthy coral reefs. They also provided video footage from an action camera, which was a great bonus.
Note on visibility: While the shipwreck is a major draw, we couldn't see it during my session due to visibility issues. It’s worth keeping in mind that nature doesn't always cooperate, but the rest of the dive more than made up for it.

Facilities & Logistics
The logistics were handled very well:

Changing Rooms: Clean and accessible facilities to change out of wet clothes both after the pool session and after returning from the jetty.

Refreshments: Proper snacks were provided, which were much appreciated after the energy-intensive dive.

Safety: The 1:1 instructor-to-student ratio during the dive made the whole experience feel very secure.

Verdict
If you want a "real" diving experience rather than a rushed tourist activity, this is a solid choice. It felt safe, organized, and honest. FlyingFish scuba surely made th diving experience memorable!

 Trustindex verifies that the original source of the review is Google. - Did an Open Water DiverScuba course with flying fish scuba in goa. This course stands out because at the same course price across India you get 4+2 speciality course dives, which can hugely improve your performance. As there base is at novotel candolim, you get better convenience if you decide to stay at the resort.

- Our instructor was Anirudh. He was amazing, supportive and clarified all our doubts. You can trust him and his experience. You will learn a lot over the duration of course.

- Dive sites are amazing both the wreck and coral colony.

Happy Diving!

 Verified 40+40 scuba diving
It’s spell bounding experience, I can’t express my happiness. I took 40+40 min long scuba diving . That was intensive and tedious though. I was very eager to see corals and under water 🗺️ world. My instructor Dinesh who truly genuine, with lot of patience listened to me because I was very very anxious once dived into sea!!! I almost gave up, but I asked him 5 mins and repeated the same pool training, eventually I made it😍❣️!! I dived deep equalising my ears often as I have sinusitis problem that caused sharp pain in my ears. My instructor was really helpful and cooperative. Thank you flyingfish scuba for making my dive easier and possible 🪸💖💙
