Advanced Nitrox Diver


This course examines the use of EAN-21 through 100 percent oxygen for optimal mixes to a depth of 40 metres / 130 feet. The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN-21 through 100 percent oxygen for dives not requiring staged decompression. TDI Decompression Procedures or the Intro to Tech may be combined with this course at the discretion of the instructor.


Class Duration:  The minimum number of classroom and briefing hours is 6

*A 3-way combination of TDI Intro to Tech or TDI Sidemount, Advanced Nitrox and Decompression Procedures is permitted with a minimum of 8 dives required. The prerequisites for advanced nitrox and decompression procedures diver must be met for this combination before starting the program.
