Advanced Nitrox - Deco procedures

The use of oxygen and oxygen-enriched air mixture is critical to advanced applications in diving. This course will arm you with the knowledge and understanding of the risks and benefits associated with these gases.

You have been enjoying your recreational diving, and you are ready to go a step further. Then, the TDI Advanced Nitrox course is an excellent introduction to the world of Technical Diving. During your education, you will complete deep dives to 130ft/40m in the safest manner possible with no stage decompression and using Nitrox up to 100% oxygen. You will tune up your buoyancy control in a new configuration and work on stress management and problem-solving. And also very important in technical diving, you will start planning your dives.

This TDI Advanced Nitrox course combines perfectly with the Decompression Procedures course and will be the foundation of your technical diving career and, of course, give you a better understanding of technical diving.

It is just the beginning of the progression into more advanced applications in diving.
