Hello,
I am new to the forum and wish everyone great diving. I am curious... has anyone besides myself attempted freediving on nitrox? I have been experimenting with taking nitrox 32,36 breaths at the surface and freediving. The point is to curb shallow water blackout due to the fact that although CO2 levels can rise before the PO2 drops too far. This should prompt you to get to the surface before you run out of O2. (at least for those who have not conditioned themselves to not respond to rising CO2.
Hold on while I brace myself for the wave of criticism...
