Deco with too less air, options from the book

[Tortuga68]

Is this comment not condescending?

It wasn't intended to be. I thought my comments were accurate, albeit subjective - happy to discuss further via PM if you wish, thread already has enough off-topic content IMHO

Criticism of ScubaBoard for the topic isn't appropriate IMO.

I've been in this thread since early on. To summarize...

The original question is poorly worded, but the essence of what the OP was asking has been discussed.

As with any internet forum, there will be some wandering from the original topic. ScubaBoard doesn't have the moderator resources available nor does SB have interest in being so rigid that every thread must adhere explicitly to the topic without any wandering from it. It is too bad that you can't read through the posts yourself to see the valuable posts in this thread, which there are many, and refer to this as the worst thread on SB??

Also keep in mind that this isn't a "basic scuba discussion" this is an advanced topic, and discussion of theory, where many people will disagree, since theory is - just that...

When I first began decompression diving, there was no deco training, tek training agency, or interenet. We learned exclusivley by experience, and open discussion with our peers. The What If Game, has always played a prominent role in becoming better equiped divers. Open discussion is good, but it is always important to consider the source for any concept, especially if we try to carry this information into the water with our lives literally hanging in the balance.

Decompression theory today, is different than it was 5 years ago, and what we thought to be gospel 5 years ago is radically different than what we believed 5 years before that. Therefore, I think I can reasonably expect that in 2013, our approach to decompression might be significantly different than today?

This is complex stuff that requires significant insight that is only brought about by diving experience, education, independent study and contemplation of the universe. It can't be figured out in an afternoon. Still at the end of the day, the science is just theory, and what we rigorously defend today will most likely be abandoned as voodoo BS tomorrow.

Not one of us has all the answers, so maybe we should lighten up. A little. This should be fun.


Cheers

I've 'been in this thread since early on' too, and read every post

Frankly, I find your comments unwarranted, innacurate and condescending. However rather than continue the discussion here, I will send you a respectful, politely worded PM

I'm disappointed that you couldn't do the same

As am I that you continue to criticize Scubaboard publicly. Like all forums, TV, Radio, etc. We all have the ability to not read what we don't like.

I'm sorry you've found that this thread is so terrible.

John, Thanks for the reality check. It is supposed to be fun. My earlier response to this thread could have been friendlier and future ones will be. All in all, this discussion has been very informative. Thanks to all for their input.

I didn't criticize SB at all; PM sent

I'm pretty new to scuba--I think at this point I've figured out some of the things that I don't know yet and I'm positive I know enough to get myself killed. That being said when I first strapped on a tank and asked how long it would last, my instructor said about an hour (calm down it was discover scuba not OW). We all know that's a stupid question now, but every one of us at some point, all of us wouldn't have thought it was. He answered my question and most importantly, didn't crush my interest in the sport.

I come to scubaboard because I don't know, but this is a tough crowd. I'd be afraid to ask a question of this group! We ceratinly don't want to get someone hurt with a bad answer but we want to learn and have fun while staying safe.

As I understood the answers (and my apologies to h90--all north americans aren't mean)

1--don't do it if you aren't trained for it
2--plan for it properly
3--if you screw it up you're an idiot
4--if you are an idiot you are still 100+ feet under water and short on gas
5--so, like I learned about how long a tank really lasts, the answer is it depends but generally blow off or shorten the deeper stops and keep to the shallower ones.

I'll probably never tec dive, but I am interested in learning more about the sport--everything I learn makes me a better (read safer) diver. The physiology of deco stops actually helps me understand my safety stop better so thanks to those who tried to answer the question. Some day when I have a question I hope some of you will help me learn.

I don't want to continue the hijacking of this thread from the original question to "SB posting ethics", but I think the aggressiveness of responses varies by forums.

- New to diving - everyone is super nice, albeit sometimes a bit patronising
- Basic scuba discussions - everyone tries to be friendly and avoid flaming
- Advanced scuba dicsussions - egos start to clash, people can get sometimes hostile
- Technical diving specialties - surprisingly people seem more conciliatory and accepting of different approaches, although things do get warm from time to time
- DIR - those who challenge the gospel are burned alive for heresy

All of which is to say (slightly flippantly), I wouldn't be turned of SB just because you get flamed once, or some people start shouting at each other. It is a pretty useful forum, but it suffers the same drawbacks as all forums where humans have to interact with each other.

I would do it the other way around ... for reasons I explained earlier in this thread.

I realize you're trying to be flippant, but I think what it boils down to is that the higher the risk of serious damage to the diver, the more assertive people are going to get trying to talk them out of doing stupid things. Nobody really wants to see someone, through ignorance, put themselves in a position to get hurt or killed.

And I also realize that the OP in this thread was speaking hypothetically (or at least, I hope so) ... but those who replied that you should just not put yourself in this situation were not being egotistical ... they were providing the best response to the stated problem. Once you start tech diving, contingency planning isn't optional ... and blowing off stops should only ever be a last resort when all your contingency plans went to hell and you have to make a choice between getting bent or getting dead. If you end up having to make that choice, it SHOULD mean that several things have gone wrong with the dive. For a properly planned tech dive, the chances of such a thing happening should be so slim as to be almost non-existent.
