The debate rages on, just what can't you do on an manual rebreather...dive in zero Viz? No way you say? As promised I simulated pea soup Viz to see if in fact one is able to monitor their po2. What better than to demonstrate this than with real pea soup!
None of this is recommended and individual experience may very!
Bon Appetite!
YouTube - The Shearwater HUD in Pea Soup!Nice, but how did you get the PPO2 up to 1.2?
