Thanks Beester that is how we dive locally. On trips to Cribb wife likes to have DM, I tend to let her follow the leader and drift off a bit keeping her with in my vision as she has her eyes on the DM butt. Never to far as the look I get on top is not fun.
Last trip first ever ocean dive for my just cert 16 yo son the 2nd dive his tank slipped down and almost off. I was near him and reset the strap. Both I and the DM checked his gear before he went in, the strap must have expanded just enough to let the tank slide-down. I had it fixed before the DM could swim over. He has done over 10 dives with his new gear without this issue. He stayed calm and did well, his air usage did get a little high <G>
