The Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.

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 an interest in moving forward with technical diving education

Course prerequisites

• Minimum age 18 (15 with parental consent)
• Minimum certification of Nitrox Diver or equivalent
• Proof of 25 logged open-water dives

What you can expect to learn:

• 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% oxygen
• Ability to enroll in Decompression Procedures

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
