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 3.370.000 IDR or a theoretical-only version for 1.950.000 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 FAQ

  • What is the Nitrox Diver Specialty Course on Gili Trawangan?

    Our Nitrox Diver Specialty Course at Manta Dive Gili Trawangan teaches you how to use enriched air nitrox, a breathing gas with a higher oxygen percentage than normal air. You will learn how to plan nitrox dives, analyse tank mixes, and manage oxygen exposure.

  • Who is the Nitrox course on Gili T best for?

    Our Nitrox course on Gili T is best for certified divers who want to extend their no-decompression limits on suitable dive profiles. It is especially useful if you already feel comfortable underwater and want to add enriched air nitrox to your diving skills.

  • How much does the Nitrox course cost in the Gilis?

    Our Nitrox course starts from IDR 1,950,000 for the land-based theory-only option. The practical option with two nitrox dives is listed at IDR 3,370,000.

  • How long does the Nitrox Diver Specialty Course take in the Gili Islands?

    Our land-based theory and oxygen analysis option can be completed in around half a day. The two-dive Nitrox option can usually be completed in 1 or 2 days, depending on the dive schedule.

  • 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.

  • What is included in the Nitrox course on Gili Trawangan?

    We offer both a theory-only Nitrox option and a practical two-dive option. The course covers enriched air dive planning, oxygen analysis, oxygen exposure, maximum operating depth, PPO2, no-decompression limits, and how to use nitrox safely within recreational diving limits.

  • What are the prerequisites for the Nitrox course in the Gilis?

    You should be Open Water certified or hold an equivalent certification before joining our Nitrox course. The minimum age is 10+, and a medical questionnaire is required, with physician approval needed depending on your answers.

  • How deep can I dive with Nitrox in the Gili Islands?
