CMAs is the "World Confederation of Underwater Activities" that has been created in 1959 by several countries (Germany, Belgium, Brazil, France, Greece, Italy, Monaco, Portugal, Switzerland, USA and Yugoslavia). Our federation (FFESSM) is linked to the CMAS. There is not really equivalence between the CMAS and PADI but we can consider that CMAS3* is like Rescue+deep, except we can dive up to 60m in club.
