Task loading? Maybe it IS a handful to work a hand held camera and a pole spear, but where we dive we really don't have that much choice. Sometimes I make the kid pull the float and work the reel, but then he has a tough time spearfishing.
So do you. Add supervising, reef hooking, shooting a camera, shooting another camera, and escaping being chased by a hungry moray, and yes, it is true... There is no attention left to be able to handle an exploded LP hose.
Why can you see that your son is task loaded with only two tasks, but you can not see that you are overloaded with seven or eight?
I normally dive solo and during lobster season, I will be carrying a reef hook attached to a reel which is attached to a float. I will also have a light, a catch bag, two knives, a snorkel, a marine radio in a pressure proof vessel, 2 smb's and possibly a third rigged with a stringer to send fish to the surface if sharks become an issue and I will be carrying a pole spear, a lobster catch net and a speargun and sometimes I am riding a scooter too, but I always have a pony bottle. Sometimes I might even be wearing a Go Pro under my hood...
...And so the logic is, "I am normally task loaded even worse, so what's the big deal?" DD, I don't have a problem with you, even if you do get angry and tell me to go away and call me names. I just can't imagine that being this task loaded is very much fun... Or safe.
What if your buddy had had this exploded LP hose problem? Which hand would you have donated a reg with? The one holding the spear, the one holding the light, the one holding the camera, the one holding the scooter, the one holding the catch bag, the one holding the reel and dive flag, or the one holding the other camera? Yes, I know that your gear is strapped to you or tied off somehow, or that you were in water with a bottom, so you could have ditched it... But my point is that - especially as a freediver, can you not see the value in simplicity? It is said that every thing you own also owns you...
I did not have a scooter, a lobster net or a speargun on the dive in this video, so I really was not task loaded. Possibly it looks like a lotta stuff, but it's really not unusual at all.
Just because it's common for you doesn't mean that you're not task loaded. Is it possible that you are commonly task loaded?
No medical science supports this. In all probability, with the vastly superior VO2 max of an athletic kid his age, he is probably as clean 30 minutes after a 50 minute dive at 60 feet, as 80 percent of divers are after 4 hours following the same dive. In other words, he is less effected by offgassing issues than most divers.
There is another thread that DD started regarding this video - in it, there is a link to Doc Vikingo's medical opinion on it and lots of medical science supporting the notion that adolescent bodies might not handle dive physiology the same way that adult bodies do. For this reason, all agencies restrict age and or depth regarding diving. With your logic, adolescents should be capable of deeper, longer dives with less surface interval... And that simply is not supported at all by the science or the age/depth restrictions offered by the dive industry agencies.
Ok, here you are understandibly confused by that which is normal for dumpster diver..he is equally task loaded while on the surface....
I don't relate to that humor, since I do not know DD on the surface or below... But I can assure you that I am not "confused" by anything that DD has said or done regarding this video and this thread. If I become confused, I will ask for clarification.
He is not in doubles, so there is no likelihood he would ever consider shutting down the valve...what he is trained to do is use a pony, or to buddy breathe, or to do a free ascent--he is a freediver after all, and at 80 feet this is as easy for him as it is for a normal diver from 12 feet.
I have understood him to say that he is a freediver and that he was also a commercial diver, even though he ignored my questions about his job description and employment. Later he said that I called him a "liar," although I never said or wrote that. I simply asked him some questions and told him it was hard to believe, which is true. Had he offered some credentials or mentioned years worked or for whom or where, I might have been more apt to believe him.
I mean, if someone asked me for whom or where, I would simply tell them... It's not like I have some ulterior motive for keeping it a secret...
The same goes with the freediving comment - as if it is relevant in this conversation. Freedivers are not breathing compressed gasses at depth - that is, they have no worries about tissue loading, barotrauma, or lung overexpansion injuries. Becoming a "freediver" at 80 feet of depth after even a few minutes of breathing compressed gas is vastly different than doing a breath hold from 0-80-0, physiologically speaking. His abilities as a freediver - assuming that they are real - do not enable him to kick to the surface, for example, as a freediver would. His limitations should be the same as any other diver's limitations - 30 fpm or 60 fpm, tops, depending on the agency and training that he was taught.
A freediving commercial scuba diver would know this. Freediving skills or not, no matter how good, do not exempt him from the physiological effects of breathing compressed gasses at depth.
He was in no immediate danger, and you witnessed him not having any real concern, which would be expected given the options he still had.
Actually, what I witnessed was him screaming, "What is it!!!?" after the "boom" and his dive buddy hightailing it back to donate. I also observed him ditching a working reg for a nonworking reg. I do not agree that he "had no real concern." To the contrary, I saw him freaking out quite a bit, which, it turned out, wasn't necessary. It might have been had the problematic LP hose been on his primary reg, and not the backup system attached to his pony bottle.
Hooking to dead rock or sand by a rock is normal behavior by old timer drift divers, when they want to stop.
Yes, I am familiar.
Originally, Coca-Cola had cocaine in it and was sold as a remedy for all ails. In the 1950's, cigarettes were commonly thought to be healthy, as they provided relaxation and a "break." So? I thought in 2012 we had learned a few things... Including not to touch the reef. Not even with a big metal hook.
We have been on many dives with marine biologists, and never seen one concerned about the effects of such hooking off on non-live areas. If he had hooked a sponge or some coral, I would be blasting him just as you would.
There is no such thing as a "non-live area" on a reef, and if you want to stop, duck behind a rock or an outcropping. Or simply face into the current and kick. There's not enough current there in that video to make that impossible. Do I really need to argue not to touch the reef?
DD will give you and me many future opportunities to blast him, usually over some tropical collecting nonsense, or devils advocate silyness on solo diving.
...So I have heard. And read.
The scary thing to me is that he is the example for that 13 year-old... And a frequent poster here on this board. What if a new diver comes here and reads his stuff and thinks that deep air, task loading, solo diving is a good idea?
If I were solo, I would have immediately popped the waist band on the BC, popped the cross chest strap and pulled the tank down over my head (and hope that I remember to vent it before I do so). At that point, I would have been able to see what the problem was and take necessary action.
Certainly a slung pony is safer than back mounted and this incident provides a very vivid example of it. If the O-ring had popped on a slung bottle, it would have been off in 2 seconds and there would have been no confusion over which tank had a problem. Plus if slung, I could turn the valve on and off and get some usable air from a slung bottle (if there were a true emergency). I readily admit i sacrifice a degree of safety for perceived convenience...of course you know all this already.
As for my inability to deal with the problem.. My frst concern was my son's gear, after it was determined that he was fine, the situation became "something cool to film". Of course I could have handled it myself, but why not stress out my kid and see what he is made of and allow him an opportunity to respond in "a stressful emergency"???? It is excellent practice for him and honestly, why not allow your buddy to help you out when a problem arises on a dive. Everyone agrees he did fine..
Similarly, the issue with the eel, after I initially escaped being bitten under the rock, I could have simply grabbed his speargun and beat the crap out of the eel, but again this was another opportunity for him to demonstrate that he can handle himself underwater and deal with problem marine life. He now knows to jab the eel early (and often if need be).
Hell, on a dive last winter he had to use the pole spear on a reef shark, that was bugging us and it happened so fast I never knew he poked the shark until he told me on the car ride home. I did notice the white marks on the side of the shark.. It took some major jabbing by me and a third buddy with a speargun before he left us alone for good.
You know, in thousands of dives all over the world - including in this same area that you were diving in - I have never once experienced that problem. I have had to keep aggressive alligators off of my divers, but I have never once ever had a reef shark NOT leave me alone. I have never even had to poke at one.
In fact, I know many places in the world where they try very hard to
attract them. It takes quite a bit to even get them to come within sight, and years of training to get them to come into sight reliably. Perhaps you could teach all of us how to attract sharks.
