REGULATORS

If you think about it, breathing underwater is pretty remarkable, and it all happens because of the regulator.  The scuba regulator is a great invention that delivers the air from your scuba tank to you,  just the way you need it to breathe.  A scuba diving regulator is the hub of your dive equipment, & links many pieces of gear - your scuba tank to your BCD, submersible pressure gauge (SPG), the alternate air source (octopus) and you.  You'll always remember your first breath underwater using a regulator - it's thrilling.  However, you will soon forget it's in your mouth as you are distracted by your adventures underwater - which is why you need to have a reliable, easy breathing regulator - so you can forget.
