A couple of exercise I am doing to fine tune your skills. get to the ultimate comfort level ! Buoyancy is a fact of like water...... THE REGULATOR IS REMOVED FOR YOU TO SEE THERE IS NO LOSS OF BUOYANCY OR AIR USED IN ORDER TO CORRECT THE LOSS NORMALLY CAUSED BY OVERCLEARING A MASK *Ofcourse there will be another wise guy with a comment hose that is too long, ....that hose is the airgun I use when I teach.
