Advanced Nitrox

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
