I have done the Tauchen Schnupperkurs (Try Scuba Course - SSI) with the instructor Jana. It was my first experience with Scuba diving and It was a personal success, to be able to go under water in a swimming pool for more than 10 minutes and play throwing frisbee underwater been able to breath calmly, It was more than I expected.
Jana is a very good instructor, very passionate about diving, with good communication (very expressive) and a lot of calm that helped me to calm when I started panicking (it happened a couple of times).
I can't wait for a next class to go Open Water.
