Ye Gods,
This is what gives us PADI instructors a bad name. I don't believe in rushing people from c-card to c-card, although I firmly believe that every diver should make at least rescue-level.
I have suffered from early AOWD syndrome myself. I learned to dive in tropical waters, came home and wanted to start diving in our cold, dark Belgian quarries.
The first dive shop I went to gave me the advice to wait until later in the year until the water temperature would go up, so as to make the transition easier. I found this to be reasonably sound advice.
Four months later I signed up for an AOWD course with another dive shop somewhat closer to home. They took me - inexperienced as I was with only four real dives - on a dive to 30m in the cold and dark, where I got so scared I wanted to give up diving for good.
I wish to God they had advised me to go diving a few times to get used to local circumstances.
Besides, IMO the AOWD cert is too flimsy. As for experience, how can you possibly hope to teach someone advanced skills like navigating if they still have to get comfortable with diving itself. If you - as an instructor - seriously believe that a diver with only four training dives is ready to move on, I believe you need to reconsider your outlook on training. Or else you're the greatest instructor alive who only turns out crack divers who outclass everyone after their initial four dives.
I refuse to give in to the c-card selling game!
