The combined TDI Advanced Nitrox and TDI Decompression Procedures course is the perfect foundation for technical diving. It combines the theory from both the courses to allow divers to extend their bottom time while planning staged decompression dives.
When successfully completed, divers can use blends of oxygen from 40 to 100% to accelerate their deco while planning and engaging in decompression diving activities, not exceeding the max depth of 45m.
