I've been reading about pre-breathing O2 (the theory being that you start the dive with less nitrogen loading in your tissues than normal in order to obtain a deco advantage). On CCR we pretty much do this anyway although I might start doing it for significantly longer before deeper dives but to do it on OC would require using either an O2 rebreather on the surface before switching to OC or an extra O2 bottle just to pre-breathe. I'm not sure that the arguments / advantages are compelling enough to make this worthwhile... Maybe the cheap DAN O2 rebreather might be worth a punt but I can't see another way that makes this viable.

Sounds like a load of shit to me. Why bother?

I can see the theory behind it but have never seen it done. I dont think it works. Breathing 02 on the surface wont limit on gassing of inert gasses at depth as I understand it

I can see the logic but you would have to be doing some very extreme dives to make it even remotely worthwhile.
