The importance of maintaining gas reserve during a dive

It is crucial for divers to calculate and maintain an adequate gas reserve for their dives. This ensures that they have enough gas to complete the dive and handle emergency situations. The common rule of thirds is often used, reserving one-third of the gas for the return journey. However, it is important to consider factors such as the depth of the dive and the potential for gas not being available, such as in a gas sharing scenario. Divers need to develop a conscious approach to gas management and rock bottom reserves to account for unforeseen circumstances. This promotes safer diving practices and allows divers to handle emergencies effectively.
