| Re: PRISM Rebreather Owners manual Chris is right, most of the info you'd want can be found in Mastering Rebreathers check list in the back of the book. Other than setting the PO2 and calibrating, it's a bone simple on/off switch affair. Oh, I don't think either manual has the HUD light sequence explanation. That came as a separate hand out. Do you have any specific ?s ? -Andy |
