bailout requires the diver to ensure that at all times during the dive both cylinders have sufficient gas remaining to ensure a safe ascent, including any decompression that may be required. This requirement is based on the possibility that either of the cylinders may become unusable without warning. This requirement means that the cylinders are usually breathed in turn, and changed before the pressure drops to the critical pressure for that stage of the dive. This system is economical on gas, and highly reliable when done correctly, but relatively heavy on task loading. Side-mounted cylinders are equivalent to independent back-mounted cylinders, and the cylinder valves are easily accessible, so may be closed during periods when the cylinder is not in use, to reduce the risk of gas loss by free-flow. Gas management is the same as for back-mounted independent twins.

manifolded twin for bailout need to be able to isolate the cylinders quickly, as a major leak can drain a set in quite a short time. In comparison with independent twins, the manifolded set is less task loading through most of the dive, but requires skilled and immediate reaction in the event of a catastrophic failure, as it does not fail safe. If diving as part of a team, the risk is mitigated by the presence of buddies who can help. The position of the manifold valve is generally behind the middle of the shoulders, where it is moderately protected from bumping into the surroundings except when under an overhead, but is often very difficult for the diver to reach to operate, though this can be improved by correct fit of diving suit, stretching exercises, and practice.

pressure of 150 bar (2,200 psi). In this particular scenario the 3 litre pony is sufficient for diving at 20 meters but not 30 meters. These values may vary depending on the diver and other circumstances. A diver selecting a pony bottle can do such an analysis for his/her own breathing rates, cylinder pressure to be used, and required ascent profile, or take professional advice on the selection. Since monitoring of remaining air is a key safety issue during a dive, the submersible pressure gauge attached to the pony bottle regulator should be readable at any time during the dive.

271:— In a pony bottle system the back-up regulator is a complete diving regulator (first and second stages, and usually a submersible pressure gauge) on a separate cylinder which is not intended for use as the primary breathing gas during the dive. It provides a totally redundant emergency air supply. The size of the pony bottle cylinder is usually smaller than that of the primary scuba cylinder. It should however provide enough breathing gas to make a totally controlled return to the surface, including any required

for relatively shallow dives without decompression. The smaller 1.7 cu ft Spare Air provides approximately 30 breaths, and the larger 3.0 cu ft approximately 60 breaths at surface pressure. The number of breaths provided in practice will depend on the diver's lung capacity, depth, exertion and state of mind. An ascent from 18 metres (60 ft) at a recommended rate of 9 metres per minute (30 ft/min) and a typical residual

sufficient breathing gas for the diver to be able to reach a place of safety where more breathing gas is available, such as the surface or a diving bell. To achieve this the cylinder must contain enough gas to allow decompression if that is included in the planned dive profile. Cylinder volumes are generally at least 7 litres, and may in some cases be as much as twin 12 litre sets.

A bailout cylinder may be carried by a scuba diver in addition to the primary scuba set, or by a surface supplied diver using either free-flow or demand systems. Scuba divers may also refer to their bailout bottle as a

unaffected by the diver's own air supply in any way, but a second regulator on a double cylinder valve or a secondary demand valve (octopus) is not redundant to the diver carrying it, as it is attached to his or her main air supply. Decompression gas can be considered an alternative gas supply only when the risk of breathing it at the current depth is acceptable.
294:— The function of the pony bottle is to provide a source of breathing gas for a controlled and prudent ascent to the surface in an emergency situation, so the volume must be sufficient for that purpose. Even when doing no decompression diving, the total reserves of breathing gas must still be sufficient to supply three phases of the ascent:

Independent twin cylinders, (Two cylinders of about the same capacity mounted together on the back of the diver, each with its own regulator) are unquestionably a redundant gas supply configuration, as there is no possibility of flow from one to the other during the dive.

The use of two independent regulators on independent cylinder valves supplied from the same cylinder is a system most applicable to cold-water diving, where a regulator can ice up and free flow, so the diver needs to be able to close the cylinder valve for that regulator, and fall back on a second

The table above is constructed to show gas consumed in just such a scenario – 2 minutes at depth for bailout and preparation to ascend, a safe rate of ascent to 5 meters followed by a 3-minute safety stop. Calculations are based on a heavy breathing rate of 30 litres per minute and an initial tank

An alternative air source may be fully redundant (completely independent of any part of the main air supply system) or non-redundant, if it can be compromised by any failure of the main air supply. From the diver's point of view, air supplied by a buddy or rescue diver is fully redundant, as it is

A manifolded twin set with isolation valve is a special case. It is a redundant air supply when the isolation valve is closed, as the cylinders are then for most practical purposes independent, but not when it is open, as a leak will eventually drain both cylinders. Divers who intend to rely on a

Since their introduction in the 1980s, "Spare Air" cylinders have been the subject of debate within the diving community. The argument against them is that they do not have sufficient capacity to get a diver in many emergency situations back to the surface safely, and thus cause divers to feel a

There are several options for the mounting of a pony bottle. The most common way a pony bottle is carried is by fixing it to the side of the primary (back gas) scuba cylinder by straps or clamps, which may include a quick-release system (as in the above picture). The most common alternative is

For commercial diving using surface supplied breathing gas, the bailout cylinder is in many cases required by health and safety legislation and approved codes of practice as an obligatory component of the diving system. In this application the intention is that the bailout cylinder should hold

Effective use of any alternate air source requires competence in the associated skill set. The procedures for receiving air from another diver or from one's own equipment are most effective and least likely to result in a life-threatening incident if well trained to the extent that they do not

Recharging is done through a connector which is supplied with the unit for this purpose, and which connects to the main cylinder valve to decant air for a top-up. This is usually done by the diver before the dive. A button gauge is provided to allow the diver to check the pressure.
