I have had my Bravo for a year now, but still have not gotten it up to altitude as I don't have the masks/fittings for my O2 system. Frankly, I cannot tell what I need to buy. From what I can tell I need the Scott fitting to plug into the aircraft system, and a mask for above 18k', but do I also need a regulator of some type, or do I connect the masks directly to the aircraft system?
Looking for some advice/insight.
