The TDI Advanced Nitrox course is your first step towards becoming a certified technical diver. The course qualifies divers to use enriched air nitrox from EAN 21 through to EAN 100 percent within your current certification level to a maximum depth of 40 metres during dives that do not require staged decompression. The course picks up where TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox including:
- Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
- Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
- Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen
The TDI Advanced Nitrox course costs €550 and includes four open water dives. The course can be completed in two days and is open to any diver holding the required prerequisites.
