Fanny and Joeri both completed a set of PADI Instructor Specialties, I already wrote a post about their DUP dive but they also completed the Nitrox and the Emergency Oxygen Provider Instructor courses.
During the latter, they actually got to set up and work with a real Oxygen unit, and as the pictures shows, it was a fun event.
For the time being, that's my job done on Gili Air, their PADI IE is coming up 28th June till 30th June but by that time I'll be on Koh Samui again, preparing to start my next IDC, on Koh Samui, starting 1st July.
