A twin set may be used for many reasons. These could include the diver possessing a particularly high air consumption rate, the need to dive with more of a safety margin, or simply to dive deeper than a single cylinder will safely allow.
Many divers state that wearing a twin cylinder configuration is more stable than a single cylinder and it helps alleviate diver roll when leaning to the left or right during a dive. This would make sense as with a twin set configuration you would have a far wider surface area across your back, giving a large stable platform rather than the narrow profile offered when diving with a single.
For certain areas of diving, such as diving in an overhead environment, a twin set is almost a necessity rather than an individual choice. In these surroundings the margin for error is reduced because you cannot make a direct ascent to the surface in the event of a gas failure. In this situation a twin set would almost certainly raise the chances of a safe exit. The PSAI Twin Set course will help almost any diver expand their horizons and safety margins in the underwater world.
