Discussion on Full Face masks with communication systems

[mntdiver]

Come on Jakub, you can easily plug the comport of the M-48 if you pull the comms. The mask even comes with one or two plugs. Still trying to get rid of the Dragers, huh?

Hope you're doing well. See you in Chicago?

Patrick, actually, positive pressure has little effect under water. It was designed as an SCBA feature. The demand regulator functions (as do most FFM's) as positive pressure when the regulator is positioned lowest in the water column in relation to the air space of the mask, this being the normal swimming position. With the regulator higher in the water column, inverted, any mask will flood if you break the seal, even a positive pressure mask. The demand regulator is, for the most part, every bit as dry as a positive pressure and more user friendly.

I guess you can plug it, but I just do not like cutting the rubber of my FFM.
Trying to get rid of Dragers? Can't keep them in stock. They are selling quite well.
