TDI Nitrox Diver Course in Playa del Carmen

TDI Nitrox is where the road to technical diving actually begins, right here in Playa del Carmen. You'll learn the benefits, hazards, and proper procedures for diving nitrox mixes from 22% to 40% oxygen — plus equipment considerations, cylinder labeling, and how to analyze your own mixes.

What is Nitrox?

Nitrox — or enriched air — uses higher oxygen concentrations than the air we normally breathe. Anything above 21% oxygen counts as enriched air, and this certification qualifies you to dive mixes up to 40%.

The benefits are real: significantly extended bottom time from lower nitrogen uptake, shorter surface intervals, and — when used conservatively — reduced decompression sickness risk. Nothing eliminates DCS risk entirely except not diving, but nitrox helps stack the odds in your favor.

It's not without its own risks, though — the higher oxygen content means you should never dive any mix beyond air without proper training.
