D-rings on the diver's scuba harness or buoyancy compensator. Another possibility for smaller sets is to mount the bottle in a small carrying bag, from which it may be easily removed. This affords the opportunity of "handing off" the entire system to a buddy diver if that buddy needs to share air. This is may be a safer procedure than the buddies being connected through use of hosed regulators. The addition of a pony bottle to the diver's equipment will usually add an off-centre weight to the side on which it is mounted. To compensate for this a balancing weight may be added to the tank band on the opposite side of the pony, or in an off-side weight pocket. Attention must also be paid to where the pony bottle second stage regulator is placed during the pre-dive buddy check.

planned dive by breathing gas problems that requires a safe exit to the surface. In certain technical diving equipment configurations the use of larger pony bottles can again come to the fore, particular if the diving is not excessively deep and decompression requirements are modest. An example can be in the case of rebreathers, where the diluent gas supply is also used as a bailout bottle for rebreather failure. The capacity of the diluent bottle is very often insufficient for this bailout purpose, and an appropriate larger sized pony can serve as a "backup to the bailout".

150 bar (2,200 psi). In this particular scenario the 3 litre pony is just sufficient for diving at 20 meters but not 30 meters. A diver selecting a pony bottle would do a similar analysis for his/her own breathing rates, cylinder pressure to be used, and required ascent profile, or take advice in the selection. A submersible pressure gauge is required on the pony bottle regulator so that the pressure can be monitored during use to ensure that the diver surfaces before the gas runs out.

In this example all breathing is assumed at the elevated level of 30 litres/min.

Often in boats gas refills to these higher pressures are not available, so in these cases the pony can be filled prior to the dive trip excursion. Pony bottles are fitted with either

The pony bottle is usually used a source of redundant emergency breathing gas for the diver as a backup in the event of failure of the primary system. The pony bottle is intended for use in "bail out" situations in which the dive must be aborted and safe return to the surface must be facilitated.

In a pony bottle emergency gas system the back-up regulator is a complete diving regulator (first and second stages, and often a submersible pressure gauge) on a separate cylinder which is not intended for use as primary breathing gas during the dive. It provides a totally redundant emergency air

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. The most common alternative is "slinging" it between two

The table above is constructed to show gas consumed in such a scenario: 2 minutes at depth for "sort-out"; 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 L/min (1.06 cu ft/min) and an initial tank pressure of

There are several alternative ways to providing such a redundant gas supply for bail out purposes which are in common use in diving. These alternatives are listed in the following table along with a comment on how these solutions compare with pony bottle usage as a backup system:

The octopus is an additional second stage regulator taken off the primary first stage regulator and primary air supply. A failure of the first stage regulator or the exhaustion of the gas supply from the primary cylinder is a failure of the entire gas supply.
