Course prerequisites
- 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
