The League of Extraordinary Divers has a simple but hard-to-repeat formula: find a host with an encyclopaedic knowledge of scuba, the interviewing finesse to know when to prompt and when to just let people talk, and the clout to attract genuine scuba diving legends to the show. (It helps that Tec himself could easily be the subject of one of these episodes, given his own experience.) If you can think of a legendary diver, odds are, they are interviewed somewhere here - Dottie Fraser, John Chatterton, Richie Koehler, and many more. Tec Clark's genuine enthusiasm for scuba shines through. If you want to know the history of our great sport, start here!
