Only decided to learn to dive because my wife and I thought it was something our son would like to do (after we saw that the local dive shop had offered two OW classes at a silent auction). At the time I wasn’t that keen on the idea (different story now). The shop is a PADI affiliated shop so hence all the training I’ve done is through PADI. In the end i don’t think that it is the training organization that’s important. It’s the instructor that makes the class and I ’ve had some great instructors throught the last few years.
