TDI Advanced Nitrox Diver
Benefits or Features
Learn how to use and dive Nitrox mixes greater than 40% and what benefits they have when you combine with TDI Decompression Procedures.
Technical Description
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.
What will I be learning
1. Physics
2. Physiology
3. Formula Work
4. Equipment Considerations
5. Dive Tables
6. Dive Computers
7. Dive Planning
8. Common Mixing Procedures
9. Decompression
Before I start
1. Minimum age 18, 15 with parental consent
2. Minimum certification of TDI Nitrox Diver, or equivalent
3. Show proof of 25 logged open water dives
4. If this course is taught in conjunction with the TDI Decompression Procedures course, the minimum age is 18
What do I need
1. Alternative second stage octopus attached to a primary regulator or a redundant scuba unit; 1.9 litre / 13 cu ft minimum
2. A submersible pressure gauge
3. Depth gauge and automatic bottom timer and/or dive computer
4. Buoyancy compensator device (BCD) with power inflator
5. Line cutting device
6. Exposure suit adequate for the open water environment
7. Cylinder and regulator properly labeled and cleaned as required for EAN mixtures
8. Access to oxygen analyzer, may be supplied by instructor
What will I be doing
1. Four dives are required with a minimum accumulated bottom time of 100 minutes
2. If advanced nitrox is taught in conjunction with decompression procedures*, only a total of 6 dives are required, more may be conducted at the discretion of the instructor, with a maximum depth of 45 metres / 150 feet
3. If Advanced Nitrox is taught in conjunction with Intro to Tech*, only a total of four (4) dives are required, more may be conducted at the discretion of the instructor, but all dives must be conducted at depths within the diver’s current level of certification and no dives should exceed 23 metres / 75 feet
4. Only 2 dives from advanced wreck course may be credited towards the total dives required
5. TDI allows instructors to structure courses according to the number of students participating and their skill
level
