What? If you are incapable of monitoring your gas supply then you should not be diving and definitely should not be technical diving. Looking at your depth gauge regularly is BSAC OD/PADI OW stuff. If you are on deep air or on a too lean mix then the narcosis may impair your ability to remember to look at your gauges, so don't dive deep air and dive the right mix for the depth.

Again, if you are diving thirds and your shutdowns are rapid enough, then you should have enough gas to get you to your first gas switch, without even counting your buddy's gas supply. Even if you lose a lot of gas, I would not have a massive problem with busting some of my deep stops and extending my stops above 21m, in particular my 6m O2 stop. This is where your ingrained knowledge of deco (or the stuff written in your wet notes!) pays dividends.

The difference being that your twin set does not extend out beyond the width of your shoulders and your canister torch should be tucked away out of the slipstream under your right arm. If I carry a reel it is on my butt D-ring and my spools are in my drysuit pockets - all out the way and not a line trap. Deco or stage bottles are right in front of you and easily adjusted or disentangled, unlike a pony on the side of your twins, which is not.

This is a good example of human nature. |
This is a good example of piss-poor diving practices having tragic but easily avoidable consequences.
Safe diving,
