TDI Advanced Nitrox TDI Decompression Procedures

This course examines the theory, methods and procedures of planned stage decompression diving. This program is designed to combine the TDI Advanced Nitrox and TDI Decomression Procedures course into one course. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45 metres unless taught in conjunction with the TDI Extended Range Course. The most common equipment requirements, equipment set-up and decompression techniques are presented. Students are permitted to utilize enriched air nitrox (EAN) mixes or oxygen for decompression provided the gas mix is within their current certification level.  Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers.
