Rebreather courses

STDA provides 6 levels of training, three basic levels and three advanced levels, considering the diver level that enroll the course. There is also the Refresh CCR program, a workshop in half day or whole day with 1 or 2 in water sessions to restart diving after a period of inactivity. 2021 Flow chart REB senza Logo

Divers, already certified in R2 Deep in OC (or equivalent), can attend directly the 'Intro to Rebreather - Adv' , the fundamentals CCR training program of STDA.

The continuation is the 'Intro to Reb - Deep' course for recreational divers and the 'CCR 1' and 'CCR 2' courses for OC certified technical divers.

For all the courses it's possible to attend the theory sessions through the web. In this way you can use your time at the best. Same thing if you want to come in Italy to attend your courses. You can do the theory lessons before your coming. Contact us for more info: info@stdahq.com

Currently 'STDA' considers as rebreather of reference the followings:

 

Why CCR rebreathers?

Theoretically talking, the Closed Circuit Rebreathers are considered the 'state of the art' of scuba diving. In the past, the development of these systems, faced many stops but in the new millenium, in particular with the huge improvement of electronics technology, the closed circuit rebreathers started to have a wide diffusion. The reasons were quite obvious from long time: using for deep and/or long dives a rare, strategic and always more expensive gas as helium, the most efficient system was and is without any doubt the CCR system. CCR have also an other big advantage: a CCR is really lighter (26-36kg) than OC double tanks (>40kg minimum) or a pSCR (>45kg minimum). Your back will thank you.

Moreover, during the years STDA has acquired evidence that CCR diving decrease the risk of DCS in divers affected by PFO.


Marco Valenti, STDA founder, believes in this system for many years. He's a CCR user since 2004. He's a CCR Instructor Trainer, developer and tester.

Keeping always in mind that is a different way of diving, generally more complex, CCR needs a different appproach than the open circuit. This means that it is not obvious that an experienced open circuit diver is automatically suitable for the use of a CCR. The history and the direct experience in training have brought out it clearly.

For these reasons, STDA stares at the technical training mainly on rebreather diving, with the goal to develop the use of rebreather also in recreational diving. What it's needed, it's the 'right' rebreather and training.

Intro to Rebreather - BASIC course (STDA™)

Targets

The 'Intro to Rebreather Diving - Basic' aims to introduce the beginner into the underwater world using directly a simple rebreather system. 'Simple' for STDA means a rebreather without any particular setting to do and that, in any case of emergency, allow the diver to pass to an open circuit bailout breathing system, in a very simple and fast manner. Actually, following STDA philosophy, it means that the rebreather to use should be design specifically for recreational diving. So the program 'Intro to Rebreather Diving – Basic' is strictly related to the type of rebreather considered. Not all rebreathers can fit for this type of course. STDA carries out an assessment on the machines that can be introduced in this program based on simple and logical principles, on our long experience in training rebreather divers, suitable for a first-level course. The 'Intro to Rebreather Diving – Basic' introduces slowly the beginner into the underwater world through the development of theoretical knowledge related with the fundamentals physical laws, knowledge of physiology, diving procedures, analysis and solution of emergencies, basic theory of decompression. After the theoretical part, follow the 'dry labs' with the assembling, the cleaning, basic maintenance and the rebreather storage. The 'in water' part of the program is divided in 'confined water sessions' and 'open water dives'. During these parts, the beginner will be introduced to the use of the rebreather starting step by step, in a confortable environment and introducing him to all the fundamentals skills for his safety. The program includes a minimum of 6 dives, during which the instructor will ask to apply all the procedures learned in confined water sessions, up to the standards of performance expected. At the end of the course the student should be able to perform dives within the no-decompression limits, accompanied by a dive buddy within a maximum depth of 18 meters.

Prerequisites

  • be a good swimmer (be able to swim front crawl/breast stroke very easily for a distance of 250 meters without stop);
  • be able to do a free dive till 3 meters depth or 10 meters long.
  • medical certificate not older than one year;
  • non smoker
  • minimum age: 18

If the student is already certified as Open Water Diver, the instructor can ask to do a confined water session to verify the level of the skills before to start the course.

Program and duration of the course for a class of 3 students

  • Course duration: minimum 8 full days
  • Theory session and 'dry labs': 7, minimum 20 hours
  • Final assessment: quizzes with multiple choice
  • Maximum percentage of allowed wrong answer: 20%
  • Exceeding the maximum allowable percentage leads to the conclusion of the course
  • Confined water sessions: minimum 5
  • Open water dives: minimum 6 with a cumulated run time of minimum 180 minutes
  • Max bottom time: based on the minimum gas to allow a safety ascent in bailout doing a minimum deco
  • The maximum time for completion of the course: 6 months that if exceeded, the course must be repeated entirely

Limits of the certification

Max depth: 18 meters with a mandatory bailout with liters of mix available to perform a correct and slow ascent, including the minimum deco stop.

Dives within the NDL.

The certification doesn't allow to dive in overhead environment (cavern, cave, wreck, underice etc) and 'SOLO' diving
