Enriched Air Nitrox offers many physiological and practical benefits that it's hard to understand why anyone still wants to dive on air! With its higher oxygen content, diving EANx means less nitrogen in your body allowing extended bottom times and less post dive fatigue - benefits that every diver can appreciate!
The first stage of the nitrox diving program is designed to provide recreational divers with a safer breathing medium for the sport/recreational diving range. Divers may choose to dive 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 by all 3 certifying agencies and may be combined with other programmes.
The 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. Although it is not necessary to carry out dives to qualify as an EANx Diver, we strongly encourage that you get in the water and dive the gas taught throughout the training.
Must be a qualified as an Open Water Diver or equivalent
Must be a minimum of 12 years of age with a parent or guardian authorisation, or a minimum of 18 years of age without guardian approval
This is a program for safe self sufficient diving. The 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 up to 100% oxygen to a maximum depth of 45 msw (150 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 45 msw and perform decompression stops utilising EANx decompression mixtures with an oxygen concentration no greater than 1.6 pO2 for a maximum duration that does not exceed NOAA limits.
Must be qualified as an EANx 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
EXTENDED RANGE / TECHNICAL DIVING
This program is designed to train divers to conduct dives to a maximum depth of 55 msw using an EANx mixture, to provide 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 55 msw and perform decompression stops using EANx or oxygen.
Must be qualified as an Advanced EANx Diver or equivalent
Must provide 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
