However, when diving with a buddy with a higher breathing rate or a different volume of gas, it may be necessary to set one third of the buddy's gas supply as the remaining 'third'. This means that the turn point to exit is earlier, or that the diver with the lower breathing rate carries a larger volume of gas than would be required if both had ...
A further requirement for scuba diving in most circumstances, is the ability to achieve significant positive buoyancy at any point of a dive. [3] [5] [6] When at the surface, this is a standard procedure to enhance safety and convenience, and underwater it is generally a response to an emergency.
A Navy buddy diver team checking their gauges together. Buddy diving is the use of the buddy system by scuba divers and freedivers.It is a set of safety procedures intended to improve the chances of avoiding or surviving accidents in or under water by having divers dive in a group of two or sometimes three.
The buddy check is a procedure carried out by scuba divers using the buddy system where each dive buddy checks that the other's diving equipment is configured and functioning correctly just before the start of the dive. [1] A study of pre-dive equipment checks done by individual divers showed that divers often fail to recognize common equipment ...
However, when diving with a buddy with a higher breathing rate or a different volume of gas, it may be necessary to set one third of the buddy's gas supply as the remaining 'third'. This means that the turn point to exit is earlier, or that the diver with the lower breathing rate carries a larger volume of gas than they alone require.

Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non-air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis , and may improve ease of breathing .
The pony bottle is a minimum requirement for someone doing solo diving, as they have no alternative source of air in the form of a buddy's available tank and octopus regulator [9] if the dive is to a depth where the diver is not able to do a safe free ascent. In scientific diving operations, pony bottles can be a standard part of tethered scuba ...
