Blomman, that is the very mask and pod most of us are lusting after.

And coming from Kirby-Morgan it's not a half-breed, it's pedigree.

Ok, maybe it's state of the art but dumb as I am I still can't figure out what the benefits are compared with a FFM. With a FFM and a matching hood you can stay completely dry which is a good thing when diving in cold water. Why would one prefere this unit instead of a FFM?

This is a FFM, you will still be dry, but the main thing is that in case you need to bailout, you do not need to remove the whole mask, its enought just removing the pod. This makes it more secure when it comes to introducing another stress level in case of a problem...

Ok, I get it. A bailoutsituation will become easier to handle than with a real FFM. However, your head will not stay dry with the pod. At least not the guys head in the picture on Blue Tech's homepage.

Why not?
form what i have seen, Roger has one and i tried it one, it is like any other FFM, though it is separated in two different compartments, one for the mask and one for breathing.. When you say he will get wet, are you refering to the back of his head? in that case you are talking about helmets and not Full face mask.

There is a gap between the hood and the diver's mask in his forehead. I don't think his head will remain dry for long

That is standard for any FFM, are you thinking of a helmet or am i missunderstanding you?

You don't seem to understand full face masks or the pros and cons of the M-48's design. You want to be careful calling it stupid without that understanding.

The M-48 covers the face and keeps it dry. What makes it different from other FFMs is that it has a removable pod covering as the oral cavity which can be easily by releasing a single lever. As either the 2ndary, DSV or BOV are mounted to the pod, they can easily be changed UW, either for bailout or gas changes. It's a unique and well thought out design which makes this mask easier to use than other in those situations.

The pod also has a bellows, allowing the diver to either use the bite piece inside to minimize dead space and reduce CO2 buildup, or remove to use comms. Again, a thoughtful design.

A full-face-mask, as the name implies, covers the face. The M-48 does just that, no more, no less. A hood covers the head, and usually leaves the face open. Combine for a dry head.

The diver in said picture is wearing a neoprene hood, which doesn't seal out water, rather keeps it from freely flowing and cooling the head. If you want to keep both head and face dry, use a drysuit with integrated latex hood and a FFM (including the M-48). The latex hood will only keep the head dry, to keep it warm you'll need to wear a beanie underneath. The face seal of the FFM will seal against the latex of the hood and keep your entire head dry.
