Types of inflatable mechanisms
Automatic :
Uses a water-soluble capsule attached to the inflation unit; its mechanism pierces the CO2 cylinder and releases the gas when
submerged or when it senses other water-related triggers (e.g. water pressure). Units with automatic inflation mechanisms
may also be manually inflated by using the ripcord.
Manual :
Releases the CO2 gas from the cylinder via ripcord
Cylinder Seal Indication:
Makes it easier to determine if the CO2 cylinder is properly armed. Life jackets with cylinder seal indication are considered more
reliable. The CO2 cylinders in life jackets without cylinder seal indication must be inspected regularly to determine if they are charged.
