Logo of PSAI Professional Scuba Association International

PSAI was first founded in 1962 as Florida Divers Supply (FDS) by Hal Watts. In 1969 the name was changed to Florida State Skindiving Schools (FSSS). FSSS at the time was one of the largest dive schools in the world, with four locations in Florida and one in St. Lucia. It was as FSSS where the Golden Triangle originated and later evolved into the PSAI logo used today. As the organization had expanded well beyond the borders of Florida the name was again changed to the Professional Scuba Association (PSA) in 1988. The tenants, upon which PSA training was built, were so successful they led to further expansion into the international diving arena. Thus, in 1995 the “I” was added to PSA to make it the Professional Scuba Association, International (PSAI).
