A necessary condition for safe and pleasant diving is natural breathing in correspondence to the circumstance at any given time. With the S-30 you simply rotate the flow adjustment knob on the side with its ideal click feeling for free control of the air supply volume according to your needs. The multiple thread screws permit speedy and fine adjustment from which you can appropriately sense resistance to exhaled air, to a condition in which you feel almost no resistance.
