This is the second level of CDAA courses during which students are taught to plan dives to the rule of 1/3's of their twin cylinder gas supply (back or side mount) or CCR with 1 bail out cylinder. Additionally divers are trained to negotiate restrictions too narrow for 1 diver to pass through. Divers must at all times be close enough to donate gas (air share).
