Marek KušiakOpen Water InstructorSSI Open Water Instructor #117682
Sidemount enthusiast. He tailors training to the experience and needs of his students.
He started diving in 2006 with IANTD and over the years took courses in many diving systems with many instructors. Time and gradually gained experience have shown that courses across all organisations are very similar and that, overall, the instructor’s approach matters more than the name of the system. This is what he tries to follow during teaching and he adapts courses as much as possible to the students.
After a shoulder injury, he left technical diving for a while before deciding to try sidemount. Since then, he has fallen in love with sidemount diving. He currently mainly teaches this form of diving, which opens up new and interesting possibilities for beginners as well as experienced divers.
Divers Direct regularly organises one-day and weekend Events and diving expeditions for members of its club. And you can continue with follow-on courses right at these events.
