I'm curious...show me how deep the rabbit hole goes!

<font color='#000080'>Hi

Wondered how long this would go before we hit the 'hypotheticals'

However I'm willing to explore. I have one main light and two backup's. I have a buddy with one main and two backup's. The likelihood of no lights is extreme to say the least but zero viz can happen. Am I able to see my gauge or am I swimming in ink?

If I can see my gauge to establish my depth to do the switch then I am able to see the 3 inch lettering on the cylinder, if only by shining my gauge light on the cylinder!

But to address the 'order' I have thought this over a little and the way it goes is that you start with the deepest gas and then move out, ie 50% closest to your body and then 100%. In cave this would mean it is easier to leave stages at the max depth as you travel ie leave the 100% at 6 mtrs the 50% at 21 mtrs. In ocean we have typically different size stages, because the o2 bottle does not need to be that big as you use so little.

If vis is totally gone and I can't see my gauge then there is no difference with either method. I can't switch if I can't see my gauge or my buddy's gauge.

Think that answers it. Hypotheticals are always strange as the picture is never complete and too many assumptions are made IMHO.
