You're not only an instructor within your organization, you may also be an instructor at IFDI.
We are all together the "International Fun Diving Instructors".
My name is Olivier Dauxais. I have created IFDI to reduce your teaching expenses. Your instructor license is free of charge. No need to buy a book for your students. IFDI offers online learning for free. The certifications of your divers costs you only 3 US$ per certification. The plastic card is optional (extra cost of 5€). IFDI also provides to the divers a paying service of online diving logbook that can be digitally signed from your instructor account at no cost.
