Found a guy who uses the Apeks (Draeger) Panorama FFM.
Very impressed by this mask. The windshield nose block swing arms beat AGA nose blocks hands down. (although I'm hearing anecdotal evidence that draeger is being sold - or something to this effect and parts may be hard to come by).
He tells me he can hook up an alternate to the side and then in a hurry he can unclick the primary and the positive pressure from the alt keeps the mask from flooding. Is this true. If so, how does the adapter keep the lever on the Apeks XT 2nd stage alternate down to free flow that creates the positive pressure?
