Drysuit inflation with a rebreather

grunzster · 2nd January 2006, 21:22

I'm going to be training on the SK sometime this season.

I'm going to get the Salvo Argon first stage, and I'll mount the rig on my plate with the single piece of webbing and bungie method.

What bottle should I get?

I was thinking, since I'll only be using air for dil, for a while to just get a 3000psi 6cf Al tank, and just use air, instead of argon?

Royal Navy tests showed that Argon was only any good if heated.

Go with the air, you will have no problems.

Cheers,

Dave Cooper.

The study that I saw was flawed in that the suits were not flushed..

From lots of cold water experience and using argon,

a) when the undergarments arent thoroughly fushed with argon,it makes little difference..

b) when the proper flush is done and the garments are saturated with argon, there is definatey a perceptabe dfference..

I have a 40ct ft bottle that I carry to do my drysuit flushes.. it takes a few really good purges (fill drysuit, then vent gas and repeat) to get the air in the undergarments replaced with argon..
the fluffier the udergraments are the mre fushing that is necessary but the more oticible the change is..

I have a 1.5L/200bar ali bottle - I'll have to let you translate the numbers.
I use real argon in the winter. It doesn't make you feel any warmer but it seems to delay the time when the cold really starts to get annoying. I have only dived in freshwater-icing conditions never sub-zero salt.

Just use air and purchase good underwear (weezle). Get a 13 cf alum tank and it'll last for the weekend.

What are people's views on O2-rich DS gas, thermal-wise?

Air is good. If you don't thoroughly flush your suit you'll see more benefits having good underwear VS using argon with the same underwear. 6cft is what I use with Techdiving Limited Suit inflation integrated first stage/valve (part# reg1-argon-air): compact, very balanced, you can refill on your own tank or sneak & grab a few cft on OC tanks.

I've never actually bothered with the flush other than a check to see it's inflating. The suit tends to squeeze up a bit bouncing up and down at the top of the shot at 1bar so by the time I'm down to 6bar kind of depth I'm probably getting down towards 10% air anyway. I guess if I was diving shallow it would probably matter more.

I used a 6cf bottle on a 230fsw OC trimix dive and finished a 72min dive with 800psi left. Next time I will have a 14cf tank. 6cf should be fine for rec dives under an hour but I would have a backup the first few dives until you nail down your consumption rate.

Whenever I carry deco gas at least one mix will be 50% or less. I have used 50% in my DS with no noticable difference than using air. I don't find argon to provide any greater insulation.
My recreational config uses bailout gas 30cf doubling as suit inflation and I use dil for wing inflation.
Carrying an extra cylinder/1st stage for argon is a waste of time IMHO
