TDI Advanced Nitrox
The TDI Advanced Nitrox course is the gateway to advanced technical diving, designed for divers who want to optimize their time underwater using oxygen-enriched gas mixtures. This course will allow you to dive with Nitrox mixtures of up to 100% oxygen on dives that do not exceed decompression limits. It is aimed at divers who want to increase their safety, improve the efficiency of their dives and prepare for future technical certifications. Take your diving to the next level by learning how to manage and maximize the use of Nitrox!
Course prerequisites:
- Minimum age 18, 15 with parental consent
- Provide proof of TDI Cavern Diver certification or equivalent

¿What are you going to learn?
- Use of oxygen-enriched gas mixtures (Nitrox) , from 21% to 100%, to improve your performance underwater.
- Plan more efficient dives, with extended bottom times and less nitrogen buildup.
- Calculating partial pressure of oxygen (PPO2) and how to manage oxygen exposure to avoid toxicity.
- Advanced methods for calculating safe diving profiles using decompression software and dive computers.
- Pre-dive gas analysis and management techniques, ensuring proper Nitrox mix and planning.
This course includes theoretical development and practical application sessions, where you will put into practice everything you have learned.
