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
(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
Day 4 - 2 x Open Water Dives (both to be a minimum depth of 30 meters)
All training materials required for the course
Local shore dives included
Gases, Air and Nitrox
Stage cylinders If using your own stage cylinders and stage regs, they must be Oxygen Clean for mixes higher than 40%.
Our hire equipment is included but is limited it is highly recommended that as a technical diver, you are intimately familiar with your dive gear, and as such it is recommended that you own your own gear for this course. Please feel free to contact us prior to making any purchases, our tech instructors are always willing to offer their time and advice when it comes to gear selection. They have dived with and used a number of different brands and configurations, and will be able to provide you with detailed recommendations. Refer to the Side Mount Diver and Intro to Tec Diver web pages for equipment requirements as this course can be done in side mount or back mount configuration.
Side Mount or Intro to Tec are available in this combination course
Pool session is highly recommended for those that have not completed a Side Mount Diver or Intro to Tec course.
Pool session is included with the Side Mount or Intro to Tec bundle.
