The Oxygen Cell Is Dead, Long Live The Oxygen Cell!
The invention of the new optical cell and digital communication with the brand new Dive Computer M28 is a game changer. The good news is that you never have to buy new oxygen cells or care for the best-before-date. You don´t even have to calibrate them, nor services them. The best part: You can fit it on ANY REBREATHER, where you want to monitor your PO2.
