Nitrox Diver Specialty Course at Manta Dive Gili Trawangan

Every diver has gone through it at least once. You’re on a dive and you see something really cool but you need to start ascending because your no-decompression limit time is running out. diving nitrox changes that!

Nitrox Diver Specialty course on the Gili Islands

An intro to the nitrox diver specialty course

Embark on the Nitrox Diver Specialty Course at Manta Dive Gili Trawangan, designed for those interested in extending their underwater adventures. This course introduces divers to the benefits of using enriched air, commonly known as nitrox, in scuba diving.

Nitrox refers to a blend of oxygen and nitrogen with a higher proportion of oxygen compared to regular air. This composition allows divers to potentially increase their bottom time and enjoy longer periods exploring under the sea. The course focuses on essential skills such as planning nitrox dives, analyzing gas mixtures in scuba tanks, and understanding the management of oxygen exposure to enhance dive safety.

The Nitrox Diver Specialty Course is an opportunity to gain nitrox certification, which is an important step in a diver's journey. Holding an enriched air certification signifies a diver's ability to safely use enriched air nitrox in various diving conditions. This certification is valuable for those looking to explore deeper into the ocean and spend more time observing marine life and coral formations.

Offered in two formats, the course includes a practical option with two dives for 3.100.000 IDR or a theoretical-only version for 1.800.000 IDR. This flexibility allows divers to choose the learning style that best suits their needs and interests.

Nitrox Diving: Managing Oxygen Levels and Safety

Nitrox diving, utilizing enriched air nitrox (EANx) with higher oxygen content than atmospheric air, offers divers extended no-decompression limits (NDLs) for longer underwater stays without requiring decompression stops. Standard nitrox mixtures, like EANx32 (32% oxygen) and EANx36 (36% oxygen), reduce nitrogen absorption by increasing oxygen levels, thereby extending NDLs and allowing for longer bottom times.

The primary consideration in nitrox diving is managing the risk of oxygen toxicity, especially at greater depths and higher oxygen concentrations. Divers must adhere to the maximum operating depth (MOD) for their specific nitrox mix, determined by the partial pressure of oxygen (PPO2), usually capped at 1.4 ATA in recreational diving to prevent oxygen toxicity risks, such as convulsions.

Accurate gas mixture analysis is crucial in nitrox diving. Divers must use an oxygen analyzer to confirm the oxygen percentage in their tanks, ensuring the correct planning of dive profiles based on the appropriate MOD and NDLs. Nitrox training includes understanding the physics and physiology of using enriched air, calculating MODs, and planning dives with extended NDLs. Equipment compatibility with high oxygen levels is also vital to avoid potential fire hazards.

Nitrox diving, with its advantages of longer dives and reduced nitrogen loading, demands thorough training and strict adherence to safety protocols, particularly in gas analysis and oxygen exposure management, enhancing the overall diving experience.

Nitrox Dive Course FAQ

What is the cost of a nitrox dive course on Gili Trawangan?

The Nitrox dive course on Gili Trawangan costs IDR 3,100,000 (USD 195). This includes 2 dives analysing and using enriched air. There is also a land based theory only course which does not include any dives and costs IDR 1,800,000 (USD 110)

What is the duration of a nitrox dive course on Gili Trawangan?

The Nitrox dive course on Gili Trawangan can be completed in 1 or 2 days if you are doing 2 nitrox dives, or in just half a day if you are only doing the land based theory and oxygen analysis.

What is the maximum depth for nitrox diving on Gili Trawangan?

The maximum depth for a recreational nitrox dive in Gili Trawangan depends on the qualification level of the diver and the plan that has been made for the dive.  Generally the maximum depth is 30m but if you have a deep dive specialty then it is 40m.

What is the minimum age requirement for nitrox diving on Gili Trawangan?

The minimum age requirement for diving on Nitrox on Gili Trawangan is 10 years old, however the depth will be limited to 12m.

What is the difference between padi and tdi nitrox courses on Gili Trawangan?

The PADI Enriched Air Nitrox course, which is designed for recreational divers, focuses on using nitrox blends with oxygen percentages up to 40% to extend no-decompression dive times.

The TDI Nitrox Courses, including Nitrox Diver and Advanced Nitrox Diver, cater to divers interested in technical diving and may cover the use of higher oxygen blends, gas management, and decompression planning.

PADI's course typically covers topics such as the benefits and risks of diving with enriched air, analyzing nitrox blends, calculating maximum operating depths, and using nitrox tables or dive computers. TDI's nitrox courses often delve deeper into gas blending procedures, oxygen exposure limits, partial pressure calculations, and the use of different nitrox blends for various diving scenarios. Advanced Nitrox courses may also cover topics related to technical diving, such as gas switching and decompression planning.
