Do you want to extend your dive time? Whether you're a scientific diver or a photographer aiming to spend more time underwater, the TDI Advanced Nitrox Course is designed for you. This course allows divers to use enriched air nitrox ranging from EAN 21 to EAN 100 percent, within your existing certification level, to a maximum depth of 40 metres/130 feet, for dives that don't involve staged decompression. Frequently offered alongside the TDI Decompression Procedures course, it serves as the foundation of your technical diving journey.
Who this course is for?
The certified nitrox diver aiming to deepen their knowledge of nitrox blends with over 40% oxygen.
The certified nitrox diver aiming to enhance their underwater skills.
The certified diver interested in advancing with technical diving education.
Course prerequisites;
Must be at least 18 years old, or 15 with parental permission.
A minimum certification of TDI Nitrox Diver or its equivalent is required.
Documentation of 25 recorded open water dives.
Either Sidemount certification or sufficient experience in backmounted doubles.
What you can expect to learn?
Advanced Nitrox builds on the foundation of TDI Nitrox and provides a more comprehensive exploration of diving with nitrox, covering topics such as:
The physics and physiology associated with diving using gas mixtures that have over 40% oxygen.
Gas planning, dive tables, dive computers, oxygen restrictions, nitrogen restrictions.
Considerations for equipment, labeling of cylinders, analysis of nitrox mixtures, procedures for gas blending, and oxygen service ratings for gases containing over 40% oxygen.
Some of the skills you will complete in this course include:
Show proficiency in buoyancy control by hovering in a fixed position in the water column without using hands or feet.
Demonstrate strong awareness of your buddy and other team members by using effective communication, maintaining proximity, and engaging in team-oriented diving practices.
Show proficiency in controlling the free flow from the primary regulator, executing a shutdown cycle, and transitioning to the backup regulator.
Perform a proper safety stop while keeping neutral buoyancy
Show the capability to exchange air with a buddy, both as a recipient and a donor, in a controlled way while keeping position in the water column.
Show the proper body posture and suitable trim, like a horizontal or streamlined position when moving forward.
Show effective stress analysis with yourself and your dive buddy
