Content: Divers use the purge button when the second stage has been allowed to fill with water--for example, when a diver removes the regulator from his mouth during the regulator recovery skill . 2. Ease of Breathing Adjustment
Most regulators have a lever or knob that allows divers to adjust breathing resistance. This feature helps to prevent regulator free flow (a state when air flows rapidly out of the regulator second stage without the diver breathing from it), which typically occurs when the breathing resistance has been lowered too much. A free flow can quickly empty a tank. Many second stage adjustments have a setting labeled "pre-dive" to help prevent free flow at the surface, and one labeled "dive" for easy breathing once underwater. As a diver descends, he can adjust the ease of breathing to compensate for the increased difficulty of breathing as he descends . 3. Exhaust Valve
The second stage exhaust valve is the plastic unit that channels exhaled air bubbles away from a diver's face. The exhaust valve is usually located below the regulator's mouthpiece to channel air down and to the sides.
