I'm at the stage where I have pretty good buoyancy control - I can happily hold a deco stop horizontal without a reference line if need be, but I still think I breath too much gas controlling my buoyancy.
Basically, my speed of breathing seems to be regulated by trying to hold a depth precisely rather than a need for oxygen (ok, to expel CO2 to be technical).
I normally try to set buoyancy as neutral while holding about half a lungful so I can ascend by taking a deep breath and descend by breathing out; this works well, but means I breathe faster than I need to because I start breathing out in order to stop myself ascending.
Does anyone have any tips for improving my gas consumption (now about 25 ltr/min) without sacrificing buoyancy control?
