Regarding the link for Post #30; That's not BUD/S. That is part of the SCUBA Course at Panama City. What you are seeing is "Pool Week", also known as "Problem Solving", which every Student in the Diving Program has to pass before he or she moves on.
BUD/S has the same practice, but they use double hose regulators, as the Drager has that set up, and that is what they move to after passing Pool Week.
