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.
