A pony bottle is a small independently filled diving cylinder, often of only a few litres capacity, which forms an extended scuba set and which is fitted with its own independent regulator. In an emergency, such as depletion of the diver's main air supply, it can be used as an alternate air source or bailout bottle to allow a normal ascent in place of a controlled emergency swimming ascent. The key attribute of a pony bottle is that it provides a totally independent and redundant source of breathing gas for the diver.

Famous quotes containing the word bottle:
“Kelly: I washed my face clean the morning I woke up in your bedroom.
Griff: You got morals in my bedroom?
Kelly: You had nothing to do with it. Nothing! It was your mirror.
Griff: You must have taken a long look.
Kelly: It was the longest look of my life. I saw a broken-down piece of machinery. Nothing but the buck, the bed, and the bottle for the rest of my life.”
—Samuel Fuller (b. 1911)
