The trade name PSS, which stands for Professional Scuba Schools, was founded in the 1990s, thanks to the passion and commitment of a few experts who had been involved in training divers for over twenty-five years, first as instructors, then at top-level management of other diver training agencies.

PSS was created directly through their experience and it is thanks to this that it is the most avant-garde diver training agency operating in all branches of diving activities.

PSS can boast a number of records but it is enough to mention just two of them to understand the distance that separates it from the other training agencies:

• It was the first in the history of diving to offer an e-learning service on line.
• It was the first to set up an interactive internet site dedicated to the needs of its professionals.
