"it allows me to spike setpiont by just holding my breath for a few meters, so when i hit bottom i am ready and away with no messing about"
I read above on here. It raised a question in my mind my body needs o2 to work and I almost understand I need less as I dive deeper. but if I hold my breath I am starving my body of o2 ? ,when I start to breath again would my body just want more o2 so negate the holding breath part of the decent.
This is just a question :-) and I still dont dive rebreather....
