TDI Advanced Nitrox Diver

Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI 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 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?
