What is all this NAUI, PADI?
Different associations
Edit: but its all about the instructor not the association he is from..
What is the difference between a PADI, SSI, and NAUI certification course?
If there is a $64 question in diving this is it. PADI, NAUI, and SSI are all organizations that train and certify dive certification courses. Each intends to devise dive courses and training methods that produce safe scuba divers, with minimal risk to the students and instructors.
A certification card from a dive course by any of these three organizations will entitle you to take a dive vacation, or to fill a tank at a dive shop.
PADI is the biggest of the three; around half of the divers certified in the world take a PADI course. In Cairns three of the four Dive Schools offer PADI course, while the fourth offers both PADI and SSI courses. NAUI is primarily based in the USA.
