TDI Advanced Nitrox and Decompression Procedures

Advanced Nitrox and Decompression Procedures is the first technical course that expands the range of new technical divers. It is designed to prepare you for staged decompression diving, extending your depth range and bottom time and making possible a new category of technical dives. With a maximum operating depth of 150 feet this course significantly expands your opportunities to explore new sites and improve your abilities as a diver. Technical diving requires a different approach from recreational diving, and learning this approach along with new skills and equipment management techniques can make for a very intense and rewarding course.


Unlike recreational courses, passing this course is not guaranteed. A large portion of this course is gear driven and focuses on new components, configurations and implementations of essential gear, as well as the deployment of that gear in the water. Classroom material will be focused on the theory of decompression and accelerated decompression, as well as safe dive planning, adopting a technical mindset and working as a member of a team. In open-water students will practice their physical skills until they become muscle memory. Failure to pass the course is uncommon, but many courses require additional dives to improve critical skills which may be new to divers.
