Learn to dive with PADI

PADI stands for Professional Association of Diving Instructors and was founded in 1966 by two friends named John Cronin and Ralph Ericson. Their concerns about the scuba diving industry made them decide that the time had come to start an organization that would make it easier for people to learn how to dive.
They wanted to achieve that more people could enjoy the underwater world by giving relevant scuba dive training.
