jepuskar:If your wife supports your rebreathing activities you must have a nice insurance policy...LOL
That is a joke ofcourse...I'm trying to save someone a long hard typed rant about rebreathers and safety.
Sometimes you have to watch people. I think I saw a shadowy figure replace my Sofnolime with Puss Cat's kitty litter? Heard it works just as well until you hit a 100' when the partial pressure of NH3 (ammonia) starts a reverse thermo-kinetic, osteonecrotic reaction! Darn, these contraptions are dangerous!
