Stage Cylinder
Definition
A stage cylinder is an additional scuba tank carried during a dive to extend bottom time or support decompression obligations.
More on Stage Cylinder
Stage cylinders are used in technical diving or extended recreational dives. They are carried alongside the main back gas cylinder and are typically labeled and dedicated for specific dive phases such as travel gas, bottom gas, or decompression gas. Divers must be trained to manage stage cylinders, including gas switches, buoyancy control, and emergency handling. Proper rigging with clips and bungees is essential for streamlining and safety.
