If you want to be able to dive below 130 fsw, dive in double cylinder configuration or dive a rebreather a technical diver certification is what you need. To become a technical diver you need to be an open water diver with at least a nitrox and advanced certification. The minimum logged dives require before being a class varies, but a good number is about 25 to 50.
Introduce yourself to dive planning, physics, physiology, decompression, and decompression associated with technical diving. The Intro to Tech course is your first step to a whole new world of technical diving!
The Technical EANx (Nitrox) diver course will provide you with the skills and knowledge needed to minimize the risks of utilizing optimal breathing gas EANx mixtures of 25% through 80% (oxygen) for dives to a depth of 130 fsw / 40 msw not requiring stage decompression, using 80% EANx for decompression and 25% to 60% EANx for bottom mix.
Your instructor can combine this course with the Decompression Techniques Diver Course with additional training and dives. You’ll need to be 18 and have a minimum certification of NAUI EANx Diver and Deep Diver (or equivalent) and 50 logged dives with 10 dives on EANx to enroll in the technical EANx diver course.
INTRODUCTION TO TECHNICAL DIVING
The Introduction to Technical Diving Course (Intro to Tech) is designed as a bridge from the recreational diver to an introduction to the rigors and discipline of technical diving, and is a great preparatory course if you are considering technical diver training or interested in streamlining your equipment configuration.
Your NAUI Intro to Tech instructor will introduce you to dive planning, physics and physiology, decompression, and decompression associated with technical diving. The NAUI Technical Equipment Configuration (NTEC) course may also be available as part of your Intro to Tech course or as a separate technical course.
The Intro to Tech course is your first step to a whole new world of technical diving!
As you continue your technical diver training, one of the courses you'll want to take is Decompression Techniques, in which you will gain a working knowledge of the theory, methods and procedures of planned stage decompression diving. Your training will include a minimum of six dives including planning and executing a standard stage decompression dive less than 130 fsw / 40 msw.
Your instructor will also teach you equipment requirements including team requirements and NAUI Technical Equipment Configuration (NTEC), and decompression breathing gas mixtures (including oxygen, Helitrox, and EANx). You’ll learn the practical skills and knowledge you need for decompression diving within course parameters.
If you are 18 years of age, posses at least NAUI Master Scuba Diver, Deep Diver Specialty, Technical EANx Diver and Helitrox Diver certifications (or their equivalents), and have 75 logged dives, you may enroll in the Decompression Techniques course. With additional dives and training, your instructor may opt to combine this course with Technical EANx (Nitrox) Diver or Helitrox Diver.
The Trimix Diver Course consists of two levels, Trimix Diver Level I and Trimix Diver Level II. These courses will give you the skills and knowledge needed to minimize the risks of utilizing helium-based Trimix breathing gas mixes for dives to a maximum depth of 250 fsw / 76 msw requiring stage decompression and utilizing EANx mixtures and/or oxygen during decompression.
Your Trimix Level I instructor will teach you to plan and execute technical dives that require stage decompression and utilize helium-based tri-mix breathing gas mixtures and EANx and/or oxygen for stage decompression to depths above 200 fsw / 61 msw. In your Tri-mix Level II course, you will learn how to safely extend your diving depths down to no greater than 250 fsw / 76 msw.
To enroll in either Trimix course, you must be certified as a NAUI Decompression Techniques Diver and Technical Helitrox Diver or equivalent, and have a minimum of 100 logged dives 20 of which must have been decompression dives.
