I have found that the "AOW card" rule varies from one dive operation to another. Some will substitute a log book showing experience in similar conditions. My wife, who has over 200 ocean dives, over 50 of which are over 90 feet, has been told only once that she can't do a specific dive without a "private divemaster." That is me ( I keep my insurance current for that reason as well as the normal reasons). The fact is , there are a lot of experienced divers who do not have an advanced card, but are more competent to dive at any depth then an advanced card holder who has a total of ten dives, counting the training dives. Despite that fact, in this "modern age" where credential sometimes trumps competence, it's best to get the advanced card. And the training is worthwhile, even for old salts with over 100 dives.
