I think this was meant to be a dig on the fact that PADI has a lot of specialty courses. In case you wanted to get the names for the equivalent NAUI specialty courses, here is a partial list. There are many more. Be sure to click the More link to see how to find out about the dozens of NAUI specialty courses that are available to you.Our small group of dive friends were all discussing the difference between PADI and NAUI and how NAUI seems to incorporate many things into one whereas PADI wants money so you can get a different card each week (including how to zip up your wetsuit boots) so in good fun my 25th dive was a: Night, Altitude (4200 ft), coldwater, drysuit, PPB, shore, wreck dive!
