TDI – Advanced Nitrox Diver Course

This course can be combined with Basic Nitrox and Deco. Procedures

This course examines the use of EAN-21 through one hundred (100) percent oxygen for optimal mixes to a depth of forty (40) metres. The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN-21 through one hundred (100) percent oxygen for dives not requiring staged decompression.

Qualifications of Graduates
Upon successful completion of this course, graduates may engage in diving activities utilizing EAN-21 through one hundred (100) percent oxygen without direct supervision so long as:
1. The diving activities approximate those of training.
2. The areas of activities approximate those of training.
3. Environmental conditions approximate those of training.

Upon successful completion of this course, graduates are qualified to enroll in:
1. TDI Decompression Procedures Course.
2. TDI Extended Range Course.

Student Pre-Requisites
The student must:
1. Be a minimum age of fifteen (15) [Note: UE does not offer courses for students under 18]
2. Have a minimum certification of TDI Nitrox Diver (or equivalent).
3. Show poof of twenty-five (25) logged open water dives.

Course Structure and Duration
Open Water Execution:
1. Four (4) dives are required \with a minimum accumulated bottom time of one hundred (100) minutes.
2. If Advanced Nitrox is taught in conjunction with Decompression Procedures only a total of six (6) dives are required.
3. Only two (2) dives from Advanced Wreck course may be credited towards the total dives required.
Course Structure:

Required Minimum Equipment
The following are required for this course:
1. TDI Advanced Nitrox Student Manual.
2. TDI EAD I P02 Tables.

The following equipment is required for each student:
1. Alternative second stage octopus attached to a primary regulator or a redundant scuba unit (three hundred and seventy (370) liter / thirteen (13) Cu. ft. minimum).
2. A submersible pressure gauge.
3. Depth gauge and automatic bottom timer and/or dive computer.
4. Buoyancy Compensator with power inflator.
5. Exposure suit adequate for the open water environment.
6. Cylinder and Regulator properly labeled and cleaned as required for EAN mixtures.
7. Access to oxygen analyzer (Instructor may supply).

Required Skill Performance and Graduation Requirements
Maximum training depths shall not exceed forty (40) msw / one hundred thirty (130) fsw. The following open water skills must be completed by the student during all open water dives:
1. Properly analyze gas mixtures.
2. Demonstrate adequate pre-dive planning
A. Limits based on personal gas consumption.
B. Limits based on oxygen exposures at planned depth with actual mix.
C. Limits based on nitrogen absorption at planned depth with actual mix.
3. Properly execute the planned dive within all pre-determined limits.

In order to complete this course, students must:
1. Satisfactorily complete the TDI Advanced Nitrox Course written examination.
2. Complete all open water requirements safely and efficiently.
3. Demonstrate mature, sound judgment concerning dive planning and execution.
