  Have a buddy mouthpiece on a hose that blows back into the set like the main
breathing tube does.

  PLEASE can we cut down the alphabet soup? How long does it take to type or
say `fullface mask'? Likewise, I neither have nor want an ABLJ or a BCD, not
even a ZXCVBNM or the like, but I do have and use a stab jacket, and I also
have a diver's lifejacket in case I need it.

  And with a fullface mask he can't get water into the circuit by the common
aqualung habit of letting his grip on the mouthpiece get loose so that water
keeps leaking in, or be tempted to casually take the mouthpiece out on the
surface to save oxygen or to talk and let atmospheric nitrogen into the set's
circuit. OK, so it may give the diver's face that fighter-pilot or gasmask
look, but what about it?
