Subject: Re: Poor Man's Argon was: Mexicana Dive Report
When i wreck dive i usually drop my deco bottle on the wreck anyway. The only
time i do not is when the wreck is new to me and i have difficulties finding my
way back or maybe if there are strong currents. I use a 45 cft Oxygen bottle for
anything shallower than 70m and do not bother with using Nitrox for deco on
shallower dives (like 65m for 20 min). Even though i carry only a small deco
bottle it gets substantially easier to swim without it and it is unwise and
sometimes impossible to penetrate with the deco bottle on your body. As an argon
bottle i use a 0.4L or a 0.7 litter bottle. The 0.7 bottle have lasted for dives
as deep as 120m. The Argon bottle goes to my waist belt in front of my AUL type
light canister. It is completely out of the way and adds nothing to additional
drag. I put it in front of the canister to avoid that it interferes with the
deco bottle. Putting the Argon bottle on the double tanks does not work for me
while doing wreck penetrations. It gets stuck i narrow places all the time. If
you only swim on the outside of a wreck and never drop your deco bottles then it
might be a reasonable idea to inflate your suit from a deco bottle. But that is
not the kind of diving i do or probably most people do either.
