What are the 2 basic parts of a regulator called?
In it’s most basic form, a scuba regulator consists of two parts: a mechanism that accomplishes the first stage of pressure reduction (called first stage) and a mechanism that accomplishes the second stage of pressure reduction (called second stage).
What is a first and second stage regulator?
The first stage is concerned with maintaining the intermediate pressure, while the second stage is focused on keeping the same effort to inhale. You can have first staged balanced and the second stage unbalanced or both the same.
What is the difference between a DIN valve and a yoke valve?
First, what is the difference between them? The yoke is a clamp-type mounting, which is placed over the tank valve and then tightened into place. The DIN is a threaded valve, wherein you screw the regulator into the tank valve.
What happens if you vomit underwater?
The loss of fluids can contribute to dehydration, the movement of vomit through the esophagus temporarily closes the airway, and the rapid expulsion of air and vomit can cause quite a strain on the stomach, ears, and top/back of the head.

When a person is retching or vomiting, the glottis is preventing air from being released from the lungs, meaning there are the same risks to the diver as holding breath if he starts to ascend: pulmonary barotrauma or arterial gas embolism.
Whats better yoke or din?
Within the technical diving community, DIN is the standard as it is considered much safer. If technical diving is on the cards for you, it’s worth future proofing your regulator purchase by going straight for a DIN rather than purchasing a yoke and then wanting to change it later on.
