Advanced Nitrox Diver:
The TDI Advanced Nitrox course qualifies divers to use nitrox mixtures from EAN21 to pure oxygen. The maximum depth in this course is 40 meters and is a no decompression dive. This course is the foundation for your career in technical diving. The Advanced Nitrox is also a good course for divers who want to increase their no-stop time on shallow dives, such as science divers, and is a must for SCR and CCR divers.
Decompression Procedures Diver:
As a recreational diver, you have barely thought about decompression. The TDI Decompression Procedures course prepares you for planned gradual decompression. With a maximum depth of 45 meters, this course is the first step beyond the limits of recreational diving. Your TDI Instructor will teach you valuable information and skills. The TDI Decompression Procedures course combined with the TDI Advanced Nitrox course forms the foundation for all other technical diving courses. After these two courses and even more experience the way is prepared for you to take further steps in technical diving. Some of the materials you will be using are the TDI Manual for Decompression Procedures and US Navy or Bühlmann Air Decompression Tables (made of vinyl for use in the water).
The combined course runs over four days.
