Inerts Offgassing and Sharing Deco Gases

[milldog]

Like Jack Ingle uses on his trips or Joe Cornish?

I agree that support divers are not always easy to come by, but I still think they are a better option than a yellow bag especially for OC where you don't have the luxury of the very long supply of gas which you do on a CCR.

Having a discussion last night with Garf over Ada's little ascent and what we do brought it home, would we do an 85m dive without support divers? Not sure but probably pushing the limits if anything goes wrong.

I know some of your *lot on here and you really make me sick! you preach the we wouldn't do this because of A, B, or C and thats a no no, but come a dive on a good wreck 75-80m, and it's Book me as on as "other" and don't put my name down.

I just wish people who preach it stick to it, or come clean and just do the diving you want! It really does fcuk me off. It's as bad as the statement as "i like diving DIR because theres no discussions on gas time etc" NO but you spend more time congratulating each other on how good you look and what nice trinkets you just got.

FFS if we put some names here like the team who got on the boat in Plymouth with 60 bar between the three, good reserve planning, but on here they have shit loads when they get back, or the diver i was with last week who preached all sorts of protocols on here then was Solo on the boat!!

You really are a bunch of hypocritical C**** you should stop criticising others and have a long look at yourselves, this isn't a go at you GLOC but the whole DIR approach your only DIR when it suits you.

Support divers Get a life, and if the Two "DIR" who are on the Aric (80m) in September want their space binned just PM me.

One thing guys shit does happen and if you can control the fear stop yourself going for the surface and put some common sense in there you'll be OK and no training will do that for you. Garf could tell you soldiers have great training but some still run, your human!!

Even if there were DIR divers or BSAC in trouble, i couldn't care less I'd give you my gas if you sent up a yellow blob even if you didn't discus it before the dive, and if you needed it come down and give it to you

On call last night bad night

* = DIR brigade

[Garf]

just an update but mine has now dropped to about 13 - through just slowing the pace of everything on the dive down. Diving with Cave trained people teaches you a lot about taking things slowly and carefully.

Graham, I can see what you are saying.

I am going to start another thread rather than continue way off-topic Not that that doesn't happen much on a YD thread, just thought it might make more sense.

[leoc]

Hi, sorry, another slightly off-topic q. You say in this case the out-of deco gas diver switched to backgas with about 30bar in the deco bottle. Why not breathe it all?

(sorry if I've misunderstood something)

The big problem with becoming a better diver is that your SAC drops thus greatly reducing your margin of error on a dive.

Its all very well saying my sac is X Y Z but perversely if its a slightly stress elevated SAC thats a good thing as you tend to plan bigger reserves.

When you hit 10-15 sacs you may allow a 30% safety margin but thats only 15-20?? so in a poo fan interface when your sac hits 30-50 ( and thats keeping it all together) your gas reserves become seriously inadequate.


There is a good argument that experience in the water reduces the amount of incidents where your going to get seriously stressed and I totaly agree, but the fact remains that serious poo can affect any diver and any diver who refuses to acknowledge this and plan for it is in effect diving alpinist.

IE they screw up they die / get bent and they accept that risk.


Having yellow bags and drop tanks on the boat is not a sign of weakness and its not a justification to push the dive to the nth degree, its just part of your overall commitment to your family and friends to make the dive a safe as possible.

In about 8 years of doing deco diving I have never personally used a drop tank and I have witnessed it being used only twice. On the occasion I was involved in we didn't need it but seeing as it reduced the deco it made sense to use it.

However this form of emergency gas planning is a totaly separate issue to normal dive planning.

Whilst Mildogs heart felt rant may be a tad aggressive it does highlight the fact that significant errors were made by divers who shouldn't be making them.

For an at rest diver who's not involved in a specific incident to run out (or virtually run out) of deco gas is frankly astonishing. Having reserves in bottom gas to cover incidents has to be balanced out with reserves in deco gas to cover the possibility of the additional deco commitment that such an incident may incur.

Telling me the team had the reserves to cover it doesn't alter the fact the teem didn't plan the dive properly in the first place. I openly admit to diving with divers who have a laughable attitude to deco or bailout gas. I know damed well they arnt carrying enough gas but I dont really care as i am ultimately solo diving with someone along for the giggle. I have plenty of gas for me. If that person runs out and uses my'n then thats not evidence of a quality teem dive its evidence of the fact one diver planned it properly and chose to dive, knowingly or otherwise, with someone who didn't.
