How to Use Scuba Diving Regulator

Video Transcript

"Hi this is Cole with Expert Village and I'm going to be going a little more in depth with the regulator. With every regulator set up there is the first stage regulator which takes the compressed air form the tank, drops it down to an intermediate pressure, which flows through the hoses to the various attachments, the most important obviously being the primary Second stage regulator which drops the pressure down again to the surrounding water pressure, making it easier to breathe. The regulator, pretty basic, has a purge button right here, so you can blast air through to blast water out of the regulator. Mouthpiece, this particular style is nice and comfortable. There are various sensitivity adjustments and things like that but you generally don't need to mess with a regulator on a constant basis. The alternate second stage regulator is in case another diver should happen to run out of air or in the very unlikely case that the primary malfunctions in a way that it's closed which is actually designed to malfunction in a way that the air is constantly flowing. The alternate regulator also has a much longer hose so it can be passed to another diver and it's typically marked with either bright yellow or bright orange colors so it's easily recognizable as the alternate in case of emergencies."
