Who this course is for:
- The certified nitrox diver looking to expand their understanding of nitrox mixtures containing more than 40% oxygen
- The certified nitrox diver looking to expand their in-water skills
- The certified diver who has interest in moving forward with technical diving education
Course prerequisites
(these requirements must be met prior to the start of the course):
- Minimum age 18, 15 with parental consent
- Minimum certification of TDI Nitrox Diver or equivalent
- Proof of 25 logged open water dives
What you can expect to learn:
Advanced Nitrox picks up where TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox including:
- Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
- Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
- Equipment considerations, cylinder labeling, analyzing nitrox
mixtures, gas blending procedures, and oxygen service ratings for using
gases with more than 40% oxygen
Some of the skills you will complete in this course include:
- Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
- Show good awareness of buddy and other team members through communication, proximity, and team oriented dive practices
- Demonstrate the ability to manage free flow from primary regulator
in controlled fashion, shut down cycle, and switch to back up regulator
- Conduct appropriate safety stop while maintaining neutral buoyancy
- Demonstrate the ability to share air with buddy as both recipient
and donor in a controlled manner while maintaining position in the water
column
- Demonstrate correct body position; appropriate trim, such as horizontal/streamlined when moving forward
- Demonstrate proper stress analysis with self and dive buddy
What’s in it for you?
- Ability to dive using EAN 21 through 100 percent oxygen provided:
- The diving activities approximate those of training
- The areas of activities approximate those of training
- Environmental conditions approximate those of training
- Ability to enroll in TDI Decompression Procedures, TDI Semi-closed Rebreather courses, TDI Closed Circuit rebreather courses
TDI Advanced Nitrox Diver minimum certification requirements:
- Satisfactorily complete the TDI Advanced Nitrox course and written examination
- Complete all open water requirements safely and efficiently
- Demonstrate mature, sound judgment concerning dive planning and execution
