deco reg use

[drifter1430]

I use a dedicated reg for O2. For me which reg I use isn't as important as the mouth piece. I use a slightly more uncomfortable mouthpiece on my dedicated O2 reg. That way even if you had absolutely no vis, once you put the reg in you know which gas you have. This obviously isn't a priority way of identifying the stage you are using, just one more subtle precaution. I've even heard of divers twisting a rubber band across the mouthpiece to be sure to identify the O2 reg.
