At Xaloc Diving Center all our SSI Advanced courses are done from a boat.
In our courses, we follow a modular system in which you can propose your own dates to complete the course.
In addition, you can do the theory with the online system and come to Estartit just to do the practices.
Once you have completed the 4 courses and when you have a minimum of 24 logged dives, you will receive, free of charge, the SSI Advanced certification
