EANx – short for Enriched Air Nitrox – offers so many physiological and practical benefits that it’s hard to understand why anyone would still want to dive on air! With its elevated oxygen content, diving EANx means less nitrogen in you body, longer bottom times and less post dive fatigue – benefits that every diver can appreciate!
Our range of Enriched Air Nitrox diver training programs allow you to develop your skills and knowledge of EANx diving in a safe, progressive and controlled manner under the direct supervision of your Instructor.
Building upon your existing knowledge and skills, you’ll learn the benefits of EANx diving and develop your dive skills to safely and competently plan and conduct dives utilising EANx. For over twenty years, our industry-leading range of EANx programs have been at the very cutting edge of diver training…

Enriched Air Nitrox
The first step on the nitrox ladder, the IANTD EANx Diver program is designed to prneude recreational divers with a safer breathing medium for the sport diving range. Divers may elect to dive the EANx on air tables, EANx tables or computers. This course covers the use of EANx mixes in the range of 21% to a maximum of 40% oxygen.
The IANTD EANx Diver program covers dives in the 40 to 130 fsw (12 to 39 msw) depth range with the emphasis on using EANx 32 & 36. The program may be taken on its own or combined with a variety of IANTD Advanced or Specialty Diver training programs.
It is not necessary to carry out dives to qualify as an IANTD EANx Diver, but is it recommended that divers perform two dives on an EANx mixture of between 24% and 40% oxygen.
Prerequisites: Must be a qualified as an Open Water Diver or equivalent, Must be a minimum of 15 years of age with a parent or guardian authorisation, or a minimum of 18 years of age without guardian approval
Equipment Requirements: EANx Diver Student Kit, Equipment used during this program must be appropriate for the environment and in good working order.

Principles of Technical Diving with Advanced Nitrox
The foundation program for safe self sufficient diving. The IANTD Advanced Nitrox program covers the core skills from the technical diver training programs including the use of dual outlet single cylinders or twinsets with central isolation manifolds and decompression skills and procedures using bottom mixes upto 40% nitrox and decompression mixes upto 100% oxygen to a maximum depth of 42 msw (140 fsw).
An essential component of this program is equipment configuration which is covered in a series of lectures and practical workshops. The aim being to construct a safe self sufficient equipment configuration that is streamlined, accessible and promotes familiarity. Theory covered includes the EAD concept, oxygen physiology, % CNS 02 & pulmonary toxicity tracking, the use of EANx as a decompression gas, gas switching techniques, partial pressures and best mixes.
This program qualifies divers to do dive to 42 msw (140 fsw) and perform decompression stops utilising EANx decompression mixtures with an oxygen concentration no greater than 1.5 pO2 for a maximum duration of 15 minutes.
Prerequisites: Must be qualified as an IANTD EANx Diver and IANTD Deep Diver with proof of a minimum of 30 logged dives or sufficient experience to satisfy the instructor that the student has the ability and knowledge to continue into this level of training Must be a minimum of 15 years of age with a parent or guardian authorisation, or a minimum of 18 years of age without guardian approval
Equipment Requirements: Advanced Nitrox Student Kit A single cylinder with a dual outlet or a manifolded twinset A safety or decompression gas cylinder rigged as either a pony or stage cylinder. Gas cylinders must be oxygen clean and oxygen serviceable where needed

Technical EANx
This program is designed to train divers to conduct dives to depths between 30 msw (100 fsw) and a maximum depth of 51 msw (170 fsw) using and EANx mixture, to prneude greater understanding of custom blend breathing gas mixtures, a complete knowledge of the limits of any EANx mixture and the use of EANx and oxygen for decompression.
The course covers a broad level of theory and skills, focusing on the bailout procedures needed to conduct extended range dives. A major emphasis on the theory is dive planning for all failure scenarios. The course develops the core survival skills such as isolation manifold shutdowns to a higher level of performance, giving the diver increased confidence to conduct extended range dives.
The knowledge and skills taught in this program qualifies divers to safely conduct dives to 51 msw (170 fsw) and perform decompression stops using EANx or oxygen.
Prerequisites: Must be qualified as an IANTD Advanced EANx Diver or equivelent Must prneude proof of a minimum of 100 logged dives, of which at least 30 were deeper than 27 msw (90 fsw) or sufficient experience doing technical dives to satisfy the instructor that the student has the ability and knowledge to continue into this level of training Must be a minimum of 18 years of age
Equipment Requirements: IANTD Technical Diver Student Kit Fulfill general equipment requirements for technical diver programs
