SCUBA DIVING LOS ANGELES

Technical dives may be defined as being either dives to depths deeper than 130 feet / 40 meters or dives in an overhead environment with no direct access to the surface or natural light.
Such environments may include fresh and saltwater caves and the interior of shipwrecks. In many cases, technical dives also include planned decompression carried out over a number of stages during a controlled ascent to the surface at the end of the dive.
The depth-based definition is derived from the fact that breathing regular air while experiencing pressures causes a progressively increasing amount of impairment due to nitrogen narcosis that normally becomes serious at depths of 100 feet / 30 metres or greater.
Increasing pressure at depth also increases the risk of oxygen toxicity based on the partial pressure of oxygen in the breathing mixture. For this reason technical diving often includes the use of breathing mixtures other than air.
These factors increase the level of risk and training required for technical diving far beyond that required for recreational diving. This is a fairly conservative definition of technical diving.
Technical dives may alternatively be defined as dives where the diver cannot safely ascend directly to the surface either due to a mandatory decompression stop or a physical ceiling.
This form of diving implies a much larger reliance on redundant equipment and training since the diver must stay underwater until it is safe to ascend or the diver has left the overhead environment.
Is technical diving for you?
Hollywoodivers Technical Courses are designed for divers whose interests include diving beyond traditional recreational limits . Accordingly, our technical diving courses are designed to provide more detailed training than specialty diver courses, and result in more extensive qualifications.
Hollywoodivers' Technical Instructors are trained to not only qualify you for your dive objective, but also to give you a healthy respect for the technical diving environment.

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!
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.
We 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.
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.
We 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, we may opt to combine this course with Technical EANx (Nitrox) Diver or Helitrox Diver.
The NAUI Heliair Diver course provides the training and experience you need to competently plan and execute extended range dives that require stage decompression utilizing Heliair and EANx and/or oxygen. You’ll learn the hazards and proper use of Heliair for dives to maximum of 180 fsw / 55 msw that require stage decompression, utilizing EANx mixtures and/or oxygen during decompression.
This course may be combined with the Decompression Techniques Diver Course with additional dives and training. As with all courses, there are minimum requirements: for Heliair Diver, you must be 18 years of age; have logged at least 75 dives, (10 of which must be decompression dives in the environment in which the course is being taught); and be certified as a NAUI Technical EANx Diver, Decompression Techniques Diver unless combined with this course, and NAUI Helitrox Diver or equivalent thereof.
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.
