Les plongeurs déjà certifiés en circuit ouvert commencent le cours «Intro to Rebreather - Adv», le cours principal de la formation CCR STDA. L'avancement est de suivre les cours CCR 1 et CCR 2 pour les sous-marins possédant déjà une certification en circuit ouvert.

STDA fournit également le cours de débutant sans aucune certification de circuit ouvert avec le programme 'Intro to Rebreather - Basic', à ce jour seulement avec aSCR Explorer Hollis.

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:

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 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 - Deep

The 'Deep' program provides an extension in depth of the 'Intro to Reb - Adv.' course and aims to refine the 'Intro to Reb- Adv' skills, including trim, buoyancy and Fundamentals skills.Copertina Intro DEEP vers 0 9 0 web

With a maximum depth of 40 meters the 'deep' program introduces the diver in the use of normoxic mixes, like Tri-Mix 20/25 or a hyperoxic mix with ASCR. The course is dedicated to divers that come from recreational diving experience. (OC Technical divers with also the 'Intro to Rebreather - Adv' certification can attend directly the CCR1 - CCR2 courses)

The dive profile should stay always inside the NDL, following the dive planning, using a dive computer or the Mnemonic Dive Planning STDA.
