IANTD's range of Enriched Air Nitrox and Trimix diver training programs allow you to develop your skills and knowledge of EANx and Trimix diving in a safe, progressive and controlled manner under the direct supervision of your IANTD Instructor.
Building upon your existing knowledge and skills, you'll learn the benefits of EANx and Trimix diving and develop your dive skills to safely and competently plan and conduct dives utilising EANx and Trimix. For over twenty years, our industry-leading range of EANx and Trimix programs have been at the very cutting edge of diver training...
Nitrox Diver (40m) | (1 day)
|
|||
The first step on the nitrox ladder, the IANTD EANx Diver program is designed to provide 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 12m to 40m 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. |

Recreational Trimix Diver (40m) | (2 days)
|

The IANTD Recreational Trimix Diver program provides Sport Divers with a safer breathing medium within the depth limits of sport diving (40m), whilst utilising helium to give an Equivelent Narcotic Depth (END) of between 12m and 24m. The diver may elect to dive the 'mix' on IANTD Recreational Trimix tables or computers. The IANTD Recreational Trimix Diver program may be taught as a single course or combined with a variety of IANTD Advanced or Specialty Diver programs. The program qualifies divers to perform no stop dives using Recreational Trimix Gas mixtures within the limits of the existing qualification level to a maximum depth limit of 40m. The program covers all Recreational Trimix gas mixes from 28% to a maximum of 40% oxygen and Helium concentrations yielding an END no greater than 24m emphasizing the use of 30/25 trimix. |

Advanced Nitrox Diver (42m) | (4 days)
|
|||
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 42m. 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 requires 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 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. |

The foundation program for safe self sufficient diving. The IANTD Advanced Recreational Trimix program covers the core skills from the technical diver training programs including the use of twinsets with central isolation manifolds and decompression skills and procedures using bottom mixes of Recreational Trimix with oxygen contents between 21% and 40% with a maximum pO2 of 1.5 bar, combined with a helium content to yeild an Equivelent Narcotic Depth (END) no greater than 24 msw. 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 requires the END concept, oxygen physiology, oxygen tracking, the use of EANx as a decompression gas, gas switching techniques, partial pressures and best mixes. This program qualifies divers to dive to 51m and to perform decompression stops utilising EANx decompression mixtures with an oxygen concentration no greater than 1.5 pO2. |

Normoxic Trimix Diver (60m) | (4 days)
|

Normoxic+ Trimix Diver (70m) | (5 days)
|

Normoxic+ Upgrade (70m) | (2 days)
|
|||
The IANTD Normoxic/Normoxic Plus Trimix Diver program is designed to train divers who wish to dive to depths between 39m and 70m, but do not wish to breathe air below 39m. Trimix affords a means of managing nitrogen narcosis by reducing the Equivelent Narcotic Depth (END) to a maximum of 36 msw. The IANTD Normoxic/Normoxic Plus Trimix Diver program requires academic lectures, confined water skills development and open water dives using air, EANx or Trimix using one gas switch. Gas switching computers can be used (and are recommended) but IANTD tables must be used as a backup. These programs qualify divers to perform Trimix dives to a maximum depth of 70m using custom bottom mixes with a minimum oxygen content of 19% and a maximum of two decompression cylinders. |

Trimix Diver (100m) | (5 days)
|
|||
This program is designed for those individuals already involved in deep diving activities but wish to develop the skills, ability and knowledge to enable safe diving in the trimix depth range. It requires extensive dive planning workshops covering all bailout scenarios, run time management and choice of gases. The diver's skills are developed to the highest level to promote self sufficiency and safety whilst maintaining the ability to operate within a team. The program requires academic lectures, confined water skills development and open water dives. Gas switching computers can be used (and are recommended) but IANTD tables must be used as a backup. The knowledge and skills taught in the IANTD Trimix Diver program qualify divers to perform Trimix Dives to a maximum depth of 100 msw. |
