TDI Decompression Procedures Course
The TDI Decompression Procedures Diver course introduces the theory, methods and techniques for safely planning and performing staged decompression dives. This course is usually taken in addition to the TDI Advanced Nitrox course. This is recommended due to the advantages related to the use of Oxygen for decompression. Furthermore, the TDI Decompression Procedures course is a prerequisite for the TDI Extended Range and Trimix course.
Learn how to plan and conduct decompression dives to a maximum depth of 45 metres / 150 feet. When taken in conjunction with the TDI Extended Range Course the maximum depth is 55 metres / 180 feet. And up to 60 meters / 200 feet with Trimix. Equipment requirements, set-up and decompression techniques are presented and the use of enriched air nitrox mixes and 100% O2 is permitted for decompression as long as Advanced Nitrox training has been taken.
