Advanced EANx

The Advanced Nitrox program covers the basic skills of technical diver training programs, including the use of twin or sidemount cylinders. You will learn decompression skills and procedures using bottom mixes up to 40% nitrox and decompression mixes up to 100% oxygen at a maximum depth of 42 msw.
An essential part of this program is the equipment configuration. The goal is to build a safe configuration that is streamlined, accessible and promotes familiarity. The theory includes the concept of oxygen physiology, % CNS O2 and pulmonary toxicity monitoring, the use of EANx as a decompression gas, gas switching techniques, partial pressures and best mix for depth.

Decompression procedures

If you are an Advanced EANx Certified Diver who is looking to expand their knowledge of decompression theory and dive techniques, is interested in extending their bottom time and has an interest in advancing their technical dive education, this course is for you.
What you can expect to learn: decompression gas optimization, personal dive computers, emergency and contingency planning (equipment failure, missed decompression, etc.).
The course includes decompression diving procedures, equipment selection and configuration, pre-dive checks and drills, stress analysis and mitigation. You will learn about cylinder labeling, nitrox mixture analysis and gas mixing procedures, etc...

Advanced Recreational Trimix

The IANTD Advanced Recreational Trimix program covers all the basic essential skills of a technical diving training program, including the use of dual cylinders with center manifold or sidemount configuration, use of deco gas and introduces the use of helium in bottom gases. Trimix blends with oxygen contents between 21% and 40%, combined with helium content to produce an Equivalent Narcotic Depth (END) no greater than 30 msw can be used.
An essential component of this program is equipment configuration which is covered in a series of lectures and hands-on workshops. The objective is to build a safe, self-sufficient, streamlined, accessible and familiarity-promoting equipment configuration. Theory covered includes the END concept, oxygen physiology, oxygen tracking, use of EANx as a decompression gas, gas switching techniques, partial pressures and best trimix blends for the depth.

Technical Diver/Extender Range

This program is designed to train divers to make dives to depths between 30 msw and a maximum depth of 51 msw using EANx, to provide a greater understanding of custom blended breathing gas mixtures, a thorough 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 rescue procedures necessary to perform extended range dives. A major emphasis in the theory is dive planning for all failure scenarios. The knowledge and skills taught in this program qualify divers to safely dive to 51 msw and perform decompression stops with EANx or oxygen.

Normoxid Trimix

The IANTD Normoxic Trimix Diver program is designed to train divers who wish to dive to depths between 39 and 60 msw. Trimix mixes offer a means to manage nitrogen narcosis by reducing the Narcotic Equivalent Depth to a maximum of 36 msw. The IANTD Normoxic Trimix Diver program includes academic classes, confined water skill development and open water dives with air, EANx or Trimix . This program qualifies divers to make Trimix dives to a maximum depth of 60 msw using bottom mixes with a minimum oxygen content of 19% and a maximum of two stages for decompression.


This program is designed for those who already participate in deep diving activities but wish to develop the skills, ability and knowledge to enable safe diving in the trimix depth range. It includes extensive dive planning workshops covering all rescue scenarios, time management and gas selection. Diver skills are developed to the highest level to promote self-reliance and safety while maintaining the ability to operate within a team.
The knowledge and skills taught in the IANTD Trimix Diver programme qualify divers to conduct Trimix dives to a maximum depth of 100 msw.

Extend your limits

Those dives that you think are deep and take advantage of them extend your bottom limits. Use the right mixes for each dive, plan your dives, dive your plan. Set up your equipment correctly. Understand how it works. You will see all this and much more in our technical diving courses.
