Our philosophy

Our philosophy and target are to help you to reach the highest fun level during your underwater adventures.

To do this the only way is to follow the highest level of training, achieving the right bouyancy-trim control and performig well all basic safety drills

The first technical part of the diver must be the brain... if your brain has some 'bugs' inside about emergency management, it's only a matter of time. Sooner or later the 'bugs' will get out and you'll be in problems.

Currently STDA doesn't propose technical training course with rebreathers designed with only one display/electronic and the HUD and/or with the oxygen manual valve on the inhale counterlung.

In our opinion:

  • support the concept that during a decompression dive the HUD is enough to manage the emergency of the failure of the only one electronic/display is a falsehood, that can only helps the manufacturer to keep the rebreather cost lower;
  • support the concept that a rebreather with the oxygen manual valve on the inhale counterlung is safe, it's a falsehood
  • support that backmounted CL have the same safety level in managing emergency than on the shoulder CL it's an other falsehood

From 2008 STDA, in the person of Marco Valenti, has been the first diving school and then agency to introduce standards and procedures of the 'flying connection' to the bottom mix bail-out tank. These standard and procedures are part of the holistic rebreather training system of STDA.



There are two main rules we always try to apply and help to keep quality at an high level:

  • maximum ratio instructor/student:   1/3 (1/4 for cross over); 1/4 with an assistant instructor
  • confined water sessions: pool or very similar confined water conditions
