Main Dive Courses SSI & PADI - Acapulco Mexico

What is the difference?

In terms of diver training there is very little difference between SSI and PADI. They both follow the diving standards set by the requirements for scuba training as set forth by the International Standards Organization (ISO), the Recreational Scuba Training Council (RSTC) and the American National Standards Institute (ANSI) meaning that knowledge and skill requirements are almost the same. Certifications are interchangeable. Both organizations and your certification are recognized worldwide.
