I was just reading the thread on certification problems at http://www.scubaboard.com/showthread.php?t=171660title= I had not heard about this development. Im rather glad that Laura and I got through OW and AOW before this went into effect. Since we are husband and wife living in the same household, taking the same classes, I assumed that we were perfectly within our rights to purchase only one materials pack. Apparently our LDS did, too. From what the thread on cert problems seems to be sharing, PADI considers us as criminals bootlegging off each others course materials. Im thinking that there is more to this or certain allowable exceptions (or PADI is about to jeopardize their husband/wife business). Does anyone have further info?
