Mastering the TDI Advanced Nitrox Course at Oceans 5 Gili Air

Introduction

For divers looking to extend their bottom time and enhance their diving safety, the TDI Advanced Nitrox Course is a gateway into the world of technical diving. Conducted at Oceans 5 Gili Air, this course teaches divers how to use enriched air nitrox (EANx) blends ranging from 22% to 100% oxygen, allowing for better gas management, reduced nitrogen absorption, and increased safety margins during dives.

Located in the pristine waters of the Gili Islands, Oceans 5 Gili Air provides the perfect environment for divers looking to advance their skills under the guidance of experienced TDI Tech Instructor Ary, the only Indonesian Technical Diving International (TDI) instructor on the Gili Islands.

This article will explore what the TDI Advanced Nitrox Course entails, the benefits of taking this course at Oceans 5 Gili Air, and why this training is essential for divers looking to push their limits.

What is the TDI Advanced Nitrox Course?

The TDI Advanced Nitrox Course is designed for certified divers who want to explore the benefits of enriched air nitrox beyond recreational limits. Unlike the standard PADI Enriched Air Diver Course, which introduces nitrox diving for recreational use, the TDI Advanced Nitrox certification allows divers to use oxygen-rich gas mixes up to 100%, making it a critical step for those looking to enter the world of decompression diving or technical diving.

The primary objectives of this course include:

Understanding oxygen exposure limits and how to safely manage them.
Learning gas switching techniques to optimize dive planning.
Developing advanced dive planning skills for extended bottom times.
Gaining hands-on experience in using twinset or sidemount configurations.
Practicing emergency procedures for handling gas-related issues underwater.

This course is perfect for divers who are looking to extend their diving capabilities without moving directly into full decompression diving. It also serves as a foundation for further technical courses like TDI Decompression Procedures.

technical diving courses. Graduates of the course can continue their tech diving journey by
enrolling in:

TDI Decompression Procedures
TDI Extended Range

This makes Oceans 5 Gili Air the perfect place to start and progress in technical diving.

Course Structure and Requirements

The TDI Advanced Nitrox Course is divided into theory, confined water training, and open water dives. Below is a breakdown of what divers can expect during the course:

1. Theory Sessions

During the classroom sessions, students will learn about:

Nitrox gas physics and its benefits in diving.
Oxygen toxicity management and exposure limits.
Partial pressures and gas planning.
Equipment considerations for advanced nitrox diving.
Proper gas switching procedures.

2. Confined Water Training

In the controlled environment of the dive pool, divers will practice:

Gas switching techniques using stage cylinders.
Buoyancy control and trim with different gas mixes.
Emergency drills, including handling oxygen toxicity symptoms.

3. Open Water Dives

Students will complete four open water dives, typically conducted at depths between 20-40meters, where they will:

Execute gas switches at planned depths.
Maintain neutral buoyancy and precise trim.
Practice deco stop procedures (if applicable).
Gain experience in twinset or sidemount diving.

4. Course Prerequisites

To enroll in the TDI Advanced Nitrox Course, divers must:

Be at least 18 years old (or 15 with parental consent).
Hold a TDI Nitrox Diver certification or equivalent.
Have at least 25 logged dives.
Possess good buoyancy control and dive planning skills.

The Benefits of Advanced Nitrox Diving

By completing the TDI Advanced Nitrox Course, divers gain several key advantages:

Increased Safety & Reduced Risk of Decompression Illness

By using higher oxygen content gases, divers can significantly reduce nitrogen absorption, decreasing the risk of decompression sickness (DCS).

Extended Bottom Times

Diving with nitrox allows for longer no-decompression limits, making it ideal for wreck diving,deep reef exploration, and multi-dive days.

Better Gas Planning Skills

Divers who complete this course develop stronger dive planning abilities, learning how to manage gas consumption efficiently.

Preparation for Decompression Diving

This course serves as a stepping stone for technical diving, preparing divers for decompression stops and deeper dives.

Conclusion

The TDI Advanced Nitrox Course at Oceans 5 Gili Air is the perfect choice for divers looking
to take their skills to the next level. With expert instruction from Ary, world-class training
facilities, and access to ideal training dive sites, this course provides an unmatched learning
experience
