Nitrox is the most popular specialty certification in recreational diving for a simple reason: swap the air in your tank for enriched air (32–36% oxygen instead of 21%) and your no-decompression limits get meaningfully longer at recreational depths.
At 18 metres on standard air you have a no-decompression limit of around 56 minutes. On 32% nitrox that extends to over 90 minutes. At Havelock's best reef sites — Nemo Reef, Lighthouse, Turtle Bay — that extra time is the difference between a rushed look and a proper, relaxed exploration.
This is a 1-day specialty course. The morning covers the essential theory and hands-on gas analyser workshop; the afternoon is optional nitrox dives to put it all into practice. You leave with a globally recognised RAID Nitrox certification and the ability to use nitrox tanks at any dive centre worldwide.
One fee covers the full theory session, hands-on analyser workshop, dive computer setup training, and your RAID Nitrox digital certification. Optional nitrox dives can be added on the day.
The Nitrox course is open to any certified diver. It's one of the quickest, most practical specialty certifications you can add to your diving portfolio.
The Nitrox course is structured as a focused half-day of theory and practical workshop, with the afternoon free for nitrox dives if you want to immediately put your new cert to use.
No — it's the opposite. Nitrox actually restricts your maximum depth due to oxygen toxicity limits. On 32% nitrox your Maximum Operating Depth is 34 metres; on 36% it's 28 metres. The benefit of nitrox is extended bottom time at recreational depths (12–25m), not greater depth. If deeper diving is your goal, the RAID Advanced 35 is the course to book.
At 18 metres, standard air gives you a no-decompression limit (NDL) of around 56 minutes. On 32% nitrox that extends to approximately 95 minutes — nearly double. At 20 metres: air gives ~45 minutes, nitrox gives ~80 minutes. The shallower the dive, the greater the benefit. On Havelock's best reef sites at 12–20 metres, nitrox makes a real, noticeable difference to your dive time.
Oxygen is only dangerous at elevated partial pressures — which only occur below your Maximum Operating Depth. When you stay above your MOD (which the course teaches you to calculate and your dive computer enforces automatically), oxygen toxicity risk is effectively zero. The course exists precisely to teach you this — it's a simple calculation and the course takes the mystery out of it completely.
Yes — nitrox certification from any major agency is accepted at all dive centres that offer nitrox fills. RAID, PADI, SSI nitrox cards are interchangeable in practice. Dive centres will ask to see your nitrox cert before filling enriched air tanks; any recognised card satisfies this requirement worldwide.
Yes — and many students do. Adding nitrox to your Open Water or Advanced course lets you complete your certification dives on enriched air, getting more bottom time on your training dives and leaving with two certifications instead of one. Contact us before booking and we'll schedule the nitrox theory on your first day so you can dive nitrox from Day 2.
A nitrox-capable dive computer is strongly recommended for regular nitrox diving — it automatically tracks your oxygen exposure and warns you if you approach MOD. We provide dive computers during the course. If you plan to use nitrox regularly on future trips, investing in your own nitrox computer is worthwhile. We offer student discounts on gear at Frogman.
The listed price of ₹9,500 excludes GST. 18% GST is applicable as per Indian government regulations, bringing the total to ₹11,210. Your invoice will show the full breakdown.
Added the nitrox cert before my fun dive week at Havelock and the difference was immediately obvious. My buddy on air was calling the dive at 45 minutes while I still had plenty of NDL left on my computer. Half-day course, instant benefit on every dive after. Should have done it years ago.
I was nervous about oxygen toxicity before the course — it sounds terrifying on paper. The instructor explained it so clearly that by the end of the morning I wondered why I'd ever been worried. Stick above your MOD, which your computer handles automatically, and there's nothing to worry about. Great course, great team.
Did nitrox alongside my Advanced 35 at Frogman — completed the theory on Day 1 and all my Advanced dives were on enriched air. The extended NDLs meant we could spend more time on the deep skills without rushing the ascent. Highly recommend combining the two if you're planning an Advanced course anyway.
The analyser workshop alone is worth the course fee — knowing how to verify your own gas mix before every dive is a skill every diver should have. The theory is short and the practical is hands-on. Half a day and you leave with a qualification that benefits every future dive you ever make.
