I am an experienced diver who was originally certified (PADI) 10 years ago. I have been in love with diving ever since. I am now trying to take specialty courses and work on advancing my certification level. (OW,AOW,Nitrox are already in my pocket). PADI is advertising to "Take The Master Diver Challenge". I'd love to but the biggest challenge is finding somewhere to do it. I live in Orange County California and could go to a franchise shop such as Sport Chalet or something similar but it is expensive and hard to even get a course scheduled. I also made the mistake of doing the Nitrox course online. I had to pay for it online and then pay again to do the course at SC. Kind of a big rip-off and it still took 3 months to get my card. Why is it SO difficult? Anyone out there know??
