Forgive me, folks, but I posted this as part of a reply to another thread but thought it was appropriate here. I sincerely hope it doesn't start a flame war, because that is not the spirit in which it was presented. Rather, it is of genuine concern. Here goes...
The only pangs of usease I feel are when the very young (pre-teens) are the sole partners to what I take to be one of their parents. It's not that I'm opposed to younsters getting certified. Not at all. I do experience misgivings, however, when I see a parent "groom" their child as a dive partner at a very early age. I know that children can learn to be excellent divers, but my feelings of unease rise from fears about what might happen in an emergency. Certainly, most can handle crises with training, assuming the instructors and divemasters did their jobs in making certain the student was properly trained and is ready for the challenges of safe diving. But I have to ask just how capable a 100 pound child is of rescuing their 220 pound father (in gear, no less). My fear, in essence, is that the adult is diving essentially "partnerless". Should the adult in a child/adult partnership become impaired, it could lead in the injury or death of BOTH.
Now before I get jumped on here, let me explain the real reason for me going out on this branch. I worry most about the psychological implications of dealing with an emergency. Just say the horrible does happen, and the child is unable to save their parent (whether it was because they were physically unable to or not is irrelevant...it could be something totally unrelated to the dive that causes the accident...heart attack or some such). How capable is the child in handling the stresses and psychological damage that would likely result? I can assure you from experience, recovering from this sort of experience is tough, even for an adult. I worry that the extremely young might never recover fully.
Okay, sorry to blather on about what, in truth, is an extremely rare event. In short, I love to see young divers. I wish them all the wonder and enjoyment that a long life of diving might provide.
Godspeed.
