New topic: DIR vs. DIW

[FreediveWI]

I've used double 112's in the past, and while it was reasuring to have all that extra gas, it just wasn't nessecary. Double 80's are great for 20 minute dives down to 250', if you are using stages for your deco gas and not trying to do it all on air. They are also a lot easier on your back for normal dives.

In the past I justified double 112's becasue I could get two deep dives out of them, now I just do my first dive on a almuminum 80 stage bottle full of mix and use the doubles to fill the Bc, and for bailout. On the next dive I can either bring along another stage or switch to the gas in my back tanks. THis method is a lot easier on my back and aluminum 80's are a lot cheaper than buying an extra set of doubles. Since they are aluminum you stack a whole bunch up under your left arm, and on your left hip, without hardly noticing it that much.

I am sure the Gert will chime in here pretty soon about how he did the mixing for his Gunilda trip. THe largest tanks he used were 95's. Other friends of mine who went did 270' for 20 on double 85's without any compirmises of saftey. I was invited but too short on cash to make it. :'( Another reason to embrace freediving.
