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:
“A baby nurse is one that changes diapers and loves ‘em dearly. Get up at all hours of the night to give ‘em the bottle and change their pants. If the baby coughs or cries, you have to find out the need. I had my own room usually, but I slept in the same room with the baby. I would take full charge. It was twenty-four hours. I used to have one day a week off and I’d go home and see my own two little ones.”
—Ruth Lindstrom (c. 1892–?)
