This course combines the theory and practical skills of both the TDI Advanced Nitrox and TDI Decompression Procedures Courses and trains divers in the planning, techniques and equipment requirements for diving to a maximum depth of 45m using Nitrox mixtures or oxygen for decompression.
The course is scheduled over four days. Prior to beginning the course you will be given the 'TDI Advanced Nitrox' & ‘TDI Decompression Procedures’ workbooks. As with all our training we ask you to complete the knowledge reviews before you arrive for your academic presentation. There is also a written exam and a kit orientation.
