Content: Learn about common regulator concerns, terms, and myths. A bit of understanding and education will allow new divers to breathe easily (no pun intended!) when choosing a scuba diving regulator. What a Scuba Diving Regulator Does
Obviously, a scuba diving regulator allows a diver to breathe from a tank underwater. But how does a regulator transfer the high-pressure air from the scuba tank to the diver's lungs at a pressure that will not injure him? The purpose of a scuba diving regulator is to reduce the high pressure air in a scuba tank to a breatheable pressure on demand. Scuba regulators are simple devices, and the method in which they reduce high-pressure tank air to a breathable pressure is easy to understand. Even the simplest scuba regulators do this adequately, at all recreational diving depths and with remarkable reliability. Regulator Terminology
To understand how scuba diving regulators work, it is important to become familiar with some basic regulator vocabulary and concepts. First Stage:
