Nikki McAllen,
It always better to be prudent and emphasize safety in all activities but one needs to draw the line otherwise we would never leave our beds. First, it would be common sense that a parent would never leave a young child alone in the water without direct supervision. Basic safety concerns should always be addressed in snorkeling/skin diving lessons/instructions.
I would take an issue with you in regards to your claim of "snorkeling by an immature participant far more dangerous than SCUBA diving." The type of "hyperventilation" that would lead to "Shallow Water Blackout" is extensive hyperventilation that a child is not conditioned to do under normal circumstances. There is a considerable difference between Being excited about seeing a fish and the type of hyperventilation that is required to stay longer U/W.
In regards to equipment, proper snorkeling equipment including a vest are part of prudent involvement with snorkeling and/or skin diving.
Your statement, "With 40 years experience in the water I rarely even risk it myself," implies that you never go snorkeling and skin diving. Is this for real?
I am new here and don't want to get off on the wrong foot. Sorry if I implied any negligence, didn't mean to.
Your point about supervision is well taken, however I often see kids snorkeling together far away from the parents. Very often. If more than a three minute rescue I'm guessing that's enough for catastrophe. As I said, its a danger that can be completely off a parents radar.
If a kids wearing a vest, they aren't free diving. Sorry if I wasn't clear about that. And the reason I say SCUBA is safer for kids is because it's something they will NEVER do without adult supervision. Free-Dive Snorkeling clearly not so, and "extensive hyperventilation" is not required. Childish excitement and reckless abandon can easily do it.
Yes, I very rarely free dive ALONE. I've thought about taking an Apnea course but due to complications of dive physiology at 50 I don't think it's worth it. If really feel the need to free dive snorkel I'll carry a pony bottle for a pop or two at depth while remembering not to skip-breathe, and of course I breathe on the way up.
I did a web search with the string: 'shallow water blackout death statistics' and found a lot dire warnings and many tragedies. Seldom are drownings classified as SWB unless there is a clear reason for doing so.
Here's what I liked regarding SW Blackout:
Never attempt hyperventilating, keep breaths to four or five {count 'em sometime, not easy after exertion}.
After holding your breath underwater breath normally and relax between dives. {even when your chest is pounding}
Rest at least two times the total time spent underwater. {enough time to lose that fish}
Never use tricks to cheat the urge to breath.
Always remember to dive with an experience diver and never alone.
My point as originally offered summarized as this: Kids should not be supervised by kids. They should know heavy breathing on the surface after exertion CAN KILL THEM ! They should NOT play competitive breath-holding games. (kids !)
Simple enough. These things must be emphasized to kids as well as adults.
My friend I assure you. Anyone who takes free-diving casually is doing so at peril. It's way more dangerous than letting your kids play Soccer.
