Oh maybe, or maybe he just assumed I needed that much gas because I was going to go real deep. He works at the shop where I get my fills, so its hard to avoid him.
I guess, eventually, but I find just having the 4 regs hanging off my shoulder, I can just breathe off 1 until there's no more air, then switch to another. It's worked pretty good so far. then when one doesnt give air anymore, pass it back over your shoulder so you don't switch to it when the next one runs out of air.I think more to it get some practise up on the gear so you know where it sits on you and how it all works. I know you arent going deep but still make sure you know what reg your on and where its matching SPG is.
