i watched the german navy Waffentauchergruppe (Combat Swimmers Team) practice buddy breathing with rebreathers in their training pool and have heard some interesting descriptions of other practice sessions. The diver with the working unit has the diver-in-need behind him, swimming in tandem, a kind of doggie-style position that allows both divers to keep moving. The bottom diver (with working rig) breathes, closes valve on mouthpiece, and hands it over his head to the rider. The rider must put the mouthpiece in his teeth, open the valve, and breathe, while not losing his grip on his buddy. Then he closes the mouthpiece and hands it back to the lower guy. Needless to say, it takes some practice, whci they do, and it takes a clear head and some concentration to keep the sequence in order and not skip a step.But it can be done while still making travel progress. Also, I was told that they can have one working rig and and still share it among several divers, maintaining stealth even when everybody else's rig is kaput, by swimming in a circle with each diver coming around to get a breath in turn from the working rig. This means a terrific amount of self-control-- , sice release bubbles or a panicked diver shooting to the surface could get everyone killed. But i have also seen some amazing footage of their training exercises and i would not be surprised by anything they do. Practice, excellent physical conditioning, incredible discipline, practice, practice, practice. Of course they ain't diving for sport. Chrisopher A.
