I talked with a few divers about cave diving techniques. One said that cave divers have to change regulators every few hundred PSI to breath down the redundant tanks in unison, implying the manifold is shut off all the time. Another said that cave divers breath out of only one regulator unless it is an emergency and the 2 tanks are connected with the manifold, unless there is a need to shut off one tank. If an emergency comes up the diver will reach back to turn the manifold valve to isolate the tanks?
Are they both right or is there a generally accepted technique when cave diving to manage the air in the 2 tanks?
Thanks
