Join Swimwerks’ Enriched Air Nitrox Certification and Dive Deeper and Longer
Dive Longer, Feel Better, and Explore More on Every Trip
With nitrox, you’ll enjoy up to 40% more bottom time, giving you the freedom to fully explore vibrant reefs, wrecks, and marine life, without rushing to the surface.
Maximise Every Weekend Getaway
Whether you're diving in Tioman, Bali, or Phuket, nitrox helps reduce surface intervals and post-dive fatigue so you can spend more time underwater and less time waiting around.
Boost Your Safety and Dive Knowledge
You’ll gain essential skills in gas planning, oxygen exposure limits, and tank analysis, making you a more informed, confident, and safety-conscious diver.
Get Recognised by Dive Resorts Worldwide
An internationally accepted nitrox certification puts you ahead when booking dives, with many top dive resorts requiring or recommending it for longer, deeper sites.
Why Become an Enriched Air Certified Diver
Add Real Minutes, Not Hype
Nitrox at 32 %–36 % oxygen lets you stay 8–12 minutes longer at 18–30 m, exactly where the best reefs, wrecks, and pelagics live. That is a second pass with the mantas or the extra shots your camera has been begging for.
Built-In Safety Buffer
Lower nitrogen loading keeps you farther from decompression limits on every dive, cutting your risk of DCS and giving you room to handle surprise currents or a slower buddy without stress.
More Dives per Day, Same Vacation Time
By trimming surface intervals from roughly 60 minutes to 30, Nitrox frees up space in the schedule for a sunset macro dive or that night dive you always skip because you are wiped out.
Feel Human After Three-Dive Days
Less nitrogen equals less post-dive fog and joint ache. You head to dinner alert and energised instead of yawning through your satay.
