String:Having each diver initial/sign their own out of water column would go a long way to preventing that.
I have seen really good boat D/Ms who in fact check with every diver individually, and have them each sign the return roll. That is the best method, you are right. Fool proof. Even though fools can be so ingenious.
Speaking of ingenious, it is amazing to me that in the present incident, the threesome managed to lose one of their team, then answered up for him on the boat, and then also answered up for him again before going back into the water at the next site. Something is totally wrong, when that happens.
