STDA proposes 'Open Circuit' courses with 3 recreational levels and 3 for decompression diving. For divers that come from oher agencies that want to go on with advanced diving and don't know the hogartian configuration and the DIR approach the first course is the 'Intro to Tech'.

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 at:
