I have close to 6000 dives all over the world in various conditions; thereof now more than 1400 full cave dives and 1500+ for guided cavern tours.

I am fluent of course in German but I am also able to teach courses in English and Spanish. I am able to give easy dive briefings additionally in French and Italian.
