Nitrox and deep dive specialty
Recommended for: the ambitious scuba diver who wants to move towards technical deep diving
Nitrox and solo divers
Recommended for: Divers who travel a lot and want to prepare for diving in a variety of conditions and with changing partners
Intro-to-tech and cavern course and intro-to-cave course
Recommended for: Divers who want to learn cave diving but are not yet sure what equipment configuration they want to dive in in the future.
Sidemount course and cavern course and intro-to-cave course
Recommended for: Divers who haven’t had formal training in sidemount yet but want to start technical cave diving
Cavern course and intro-to-cave and cave course
Recommended for: Divers who already have extensive experience in technical diving (be it in backmount or sidemount) and start their training right away in their own technical equipment configuration.
The duration of the course is always based on the diver’s initial skills and the minimum days specified in your individual courses can only be reduced in a few cases in combination, because the diver learns new skills on each level that build on each other.
