Not trying to pick bones... ok maybe just a small one If the initial controlled descent is a 'skill', how can one assess their performance beforehand?
Personally I try not to start AOW before I have seen the diver in the water for at least one dive. Here in the Maldives we have the 'orientation dive' requirement which covers this. Since I've started here in Laamu Atoll running my own operation I have not needed to decline a diver from beginning AOW. IME however there will come a day...
