...
Edward, the BSAC 88s are extremely aggressive, no two ways about it. There is a reason they are known throughout the UK as the Bendy 88s

Your opinion, which you're entitled to.

However, your argument is not supported by the annual Incident Reports which appear to show more instances where computers or tables other than the 88 are used.

Kind regards

It's really easy to overestimate one's capacity in diving. A whole host of people have taken GUE Fundamentals and found the class humbling, even though all it requires is to do the simple things you learned in OW, but do them without losing buoyancy, trim, or situational awareness.

I do not at all recommend exceeding decompression limits without training. But while you are getting the experience to ready yourself for that training, you can play with stuff. Try taking your mask off and putting it back on -- without moving AT ALL. Practice air-sharing, without changing depth AT ALL, and without changing trim. Learn to shoot a bag, without changing depth, changing trim, or losing track of your buddy and your position. I think you will find these exercises challenging -- most people do. This is the kind of standard that is expected of technical divers. If you are dealing with a gear problem, gas loss, or incapacitated buddy, you need to be capable of absorbing a very large amount of task-loading, and having your basic diving skills remain ROCK SOLID. That is a level of skill well beyond someone with a handful of dives.

Thanks LeadTurn, something new I learned, I had the wrong assumtion there was a safety factor build in ( that is basically the standard ) I guess this was not the case of the person how made the US Navy dive tables.

That is the reason of what I post, to learn those things, thanks I appreasiate that light, I got me a DC for safety but I use the dive table for planing in case the DC go south on me, ascent rate is what I pay attention the most, and of course the required safety stops and DECO stops.

And right practice is the buddy system, if my DC go bad, you still have his to go by, that one go bad to, you have the depth gauge and your watch and review your table before dive, basically redundancy

Yesterday you thought you were sure you had the right equipment for decompression diving. Today you learned that the Navy tables don't have much (any?) of a margin.

Imagine what you'll learn tomorrow and what else you don't know.

Get. Proper. Training.

far to many times I hear from accidents where experienced personel make mistakes or get in to panic and they have lost it

Yes, that happens. But FAR MORE LIKELY is than an inexperienced person makes mistakes or panics.....
Play the odds, and they are not with you at your current level of training and experience.

Thanks for your light in this, hope comments and opinions are plased in profesional and educated manner.

Remy only you can answer this question - are you ready to try something that you freely acknowledge you are not ready for - for a handful of extra minutes on a wreck?

You need to answer honestly - What is the worst thing that can happen to me?

Then inform your family of your decision so that they can prepare for the worst thing - you want them to also understand your limitations and your need to stay a few more minutes...
Me - I want to dive another day and another....

By all means:

I'm wondering why you consistently capitalize DECO. It's not an acronym, it's an abbreviation for "decompression" and should thus not be capitalized.


(Nah, not really. I'm just posting to subscribe to this thread As someone so succinctly put it somewhere upthread: This can only end well.)

this is an informative thread that (hopefully) highlights one of the very clear gray lines in scuba diving: there is no such thing as "simple" deco diving. kind of like simple cave / overhead diving. and pregnancy?

Once committed, you are all in and must be prepared for the full meal deal. If you are not ready for the whole story, then do not go there. Not even a little.

P.S. why do so many rec divers harbor this need to push NDLs?

 

[Storker]

why do so many rec divers harbor this need to push NDLs?

Probably because they've never done a min gas calculation. I've done that, and I feel absolutely no compulsion to push NDLs.

An AL80 holds less gas than the normal Metric country rec tank, the 15L 200bar (or 12x232, or 10x300), and with my 15x200 I'm NDL limited instead of gas limited by just a couple of minutes at depths below 25m. Everything above that, my bottom time is limited by min gas, not by no-stop limits. So, unless I switch my collection of single tanks for a set of serious doubles (even a D8.5x232 wouldn't give me very much more gas, so I'd have to go to e.g. a D10x300 or a D12x232 to see a significant increase in gas reserves) - or strap on my beast of a 15L 300 bar - there's really no reason to push no-stop limits. Even if I were to disregard the need of a redundant gas supply, I'd be up a small stream of excrement without a means of propulsion if just a little bit of manure should hit the rotating ventilation device.

Without knowing the percent of divers using the 88, the statement may or may not be relevant.

There could be 10 times more with x than with y. But if 100 times more use x than y, then x is the safer.
