Holy S...!!

Also, in a 'bounce" dive would it not make sense to have a pressure release system so that when you hit "depth" you automatically released "some" weight to begin your ascent?

Only if those dumped weights represented true over weighting. The diver would still need a propper ascent and deco.

I have heard of such a thing for freediving where a direct ascent regardless of mind or body state is the goal.

I pose this question....I have heard that a MI could paralyze the left side of ones body, FIRST, is this true and if so, why do we not move our inflators to the right side of our bodies? Also, in a 'bounce" dive would it not make sense to have a pressure release system so that when you hit "depth" you automatically released "some" weight to begin your ascent? I am thinking along the lines of a mechanical device with the weights attached to a cord and when 300' is achieved it dumps those weights and the body, whatever condition its in, begins to return to the surface. Obviously you would not ditch all your weights or you rocket, but some to make you posatively bouyant again. Also, too many people have been lost In Blue Hole, why not have a line to the bottom and when people do bounce dives, have them attach to the line, so that if there is a problem, they pring the line up, and whoever is attached to it. Seems that common sense should be more common. Condolences to the family.

The general issue here is not planning equipment and procedures for medical emergencies during bounce dives. The issue is doing bounce dives to begin with and the inherent dangers they pose. These depths are diveable with the proper training, experience, and team. Why design a system for a manner of diving to this depth that should not be going on?

Any diver at this depth breathing anything other than trimix is subject to CNS oxygen toxicity. There is no real equipment fix for this... it should be rooted out when planning the dive. A system that automatically drops weight carries the assumptions that:

1. The diver is overweighted (which they should not be).
2. The diver wants a quick and uncontrollable ascent (which they should not).

I am with you here that common sense should enter the picture. In cases like these (if it really was a bounce dive) common sense dictates that the dive presents unreasonable and potentially unmanageable risks and therefore should not be done at all.

In case you are interested, I think this is the video that MarkUK is referring to. http://www.youtube.com/watch?v=qhcF-Coc1J0

Looking at that body and its gear you get the sense that person had no business being at that depth. Poor training, stupidity, diving way beyond ability, whatever the cause, thats Darwin at work! I see these and my heart goes out to the people that they dove with and the families they leave behind but my head says you get what you deserve.

• Good training and a smart head you get grand adventures with mitigated risk.
• Poor training or diving beyond your abilities and you end up on youtube and in the statistics books.

Is it possible that this was a suicide? There appears to have been no attempt to correct any errors or rescue himself. The speed with which he descended was phenomenal, too. Perhaps it was to prvent anyone from getting to him before he was too deep.

I think ianW2 may have it right. Perhaps it was a suicide and something he wanted to record. How sad to watch.

My wife speaks fluent Hebrew & Russian and says the Hebrew discussion subtitled into English matches perfectly. The odd points as others have already pointed out include the sound of breathing after a claim is made the regulator is out of the diver's mouth. I would like to know how that claim was made. Could video editing have put the breathing and commentary out of sync?

"Sport" by the way, would be said by both native Russian & Hebrew speakers, but it does seem a bit dramatic. Perhaps this was edited from a larger piece shown on Israeli TV and the youTube author wanted to emphasize deep diving for sport is not worth it? To shorten things for youTube posting other commentary may have been cut out. I still think the suicide theory may have some merit.

Do you guys really think an overweight person who applied a red filter first would be A) planning suicide B) doing an aggressive bounce dive ?

Doesn't fit my "profile" on either. Not sure where I got the idea the diver was fat...I think there was a shot of a very chubby arm sort of flailing by the lense, looking pretty limp already.

Does anyone else think the diver seemed to be "out of it" early on? The person never did any checks or even a pause to "collect themselves" which a diver would do before a deep bounce stunt. The diver literally just sunk like a rock.

Hebrew speakers are usually dramatic anyway, aren't they?

Could have been a dirt Dart. Got in, overweight, panic, never recover because Narcosis set in. Doesn't explain logging the depth though.

I feel like an armchair quarterback... :shakehead

what's a dirt dart?

Well, I saw that gauge shot and it seemed quite unintentional because the arm made no effort to present the face of the gauge to the lense, and it was limp.

Also, I am under the impression it takes a bit more time for N2 levels to accumulate. --any thoughts on that? This seemed to have transpired too fast for it to be narcosis at the onset.

I feel certain we are seeing seizure activity at the end...resultant from hypoxia or maybe 02 tox but we are only 4 minutes or so from the surface. 30 m/ second

(good god, your avatar is scaring me) you look like a floating filling station.

Its a great picture isn't it. I should make a caption like "Switcing to a rebreather next week"

Dirt Dart: Over weighted and uncontrolled accent.


I think I heard it first reading about the Doria. Some diver jumped in and had never tested the configuration, was way over weighted and flew to the bottom. If I remember, he actually lived but had massive ear injury

in the video it sounded like they were doing some serious equalizing and made me think of this. It took no time to hit 300 ft.

What a confusing video. Not to mention, a completely senseless death. Nothing but questions over here...

Same here. Too many questions, too little answers. The ending is the same. Really unfortunate regardless of the circumstances.
