PADI is not a newcomer.
In response to
"There was no Padi then, no BCs, no safe seconds, no SPGs and my first reg had two hoses....."
Then yes, PADI is a relatively newcomer. LA County (1954), YMCA (1959), and NAUI (1960) were all well established by the time PADI came along. Sorry if "relatively" threw you. It was in comparison to Diversauras' comments and to the older agencies which may have (he didn't mention the year) been around when Diversauras started diving.
