Content: The name “second stage” comes from this part's function as the second stage of pressure reduction. It takes the intermediate pressure air from the regulator hose and reduces it to ambient pressure-- a pressure equivalent to the air or water pressure surrounding a diver, allowing a diver to breathe from the second stage safely. The primary second stage is one of two second stages attached to a standard open water regulator, and it is this one that a diver normally breathes from during a dive. 3. Alternate Second Stage
The alternate second stage (also known as an alternate air source, buddy regulator, or octopus) does the exact same thing as the primary second stage: it reduces intermediate air pressure supplied by a low-pressure hose to an ambient air pressure that a diver can breathe. The alternate second stage is a back-up, that ordinarily is not used. It enables a diver to share air from his tank with a second diver in case of an out-of-air emergency. Alternate second stages are usually bright colors, such as neon yellow, which allows them to be quickly located. As diver education and safety procedures have evolved, alternate second stages have become standard scuba diving safety gear, allowing any diver to breathe from any other diver's tank.
