About STDA

In 2013 the project of the 'Scuba Training Development Academy' became a scuba training agency after having been a diving school.
The founder, Marco Valenti, is a scuba instructor since 1996 and has developed a huge experience in tech training since 2000. Over the years he trained many divers and instructors from different countries and for various agencies (ANDI, CMAS, DIRrebreather, IANTD, IART, PADI, UTRtek), acquiring a wide knowledge about many training systems.
During this long path, he started to develop an own system, starting to write manuals for divers and outlines for instructors.

He was the first Hammerhead instructor (February 2008) and the first HH Inst. Trainer (2010) in Europe.
Tester of the Juergensen Marine electronics, today he is the most active and experienced 'Hammerhead rebreather' instructor.
