About this course

Nitrox means diving with more oxygen than regular air, usually 32 or 36 percent instead of 21 percent. In practice, you get longer no-decompression limits at depth and faster surface intervals between dives. This course teaches you to use it safely.

  • Analysing oxygen percentage in your tank
  • Setting dive computers for nitrox
  • Maximum operating depth for different nitrox mixes
  • Equipment handling and cylinder labelling

What's included

  • PADI Enriched Air Diver certification
  • All scuba equipment
  • Nitrox tanks for the checkout dive
  • Oxygen analyser use
  • PADI Enriched Air manual

Requirements

Must hold PADI Open Water Diver (or equivalent). Min age 12.

Questions about the Enriched Air (Nitrox) Specialty course

What's the main advantage of diving with nitrox?

Longer no-decompression limits at depth, and faster surface recovery between dives. On a two-dive day in Trincomalee, nitrox adds meaningful bottom time to your second dive. The trade-off is a lower maximum depth limit. Nitrox 32 divers are limited to 34 m.

How long does the nitrox course take?

It's a short specialty, usually half a day of knowledge development and a check-out dive. No extensive pool training. If you're already a certified Open Water diver, you'll be nitrox-certified by the end of your first day.

Two wonderful family dives. It was my daughter's first time underwater, but thanks to the instructor's support, she managed without any problems. We recommend the Diving Club for its professionalism and excellent dive masters…

Great experience, saw so many dolphins on the trip and the boat driver was great with finding a good area without too many other boats
