Manual version:Before or after falling into the water, pull the rope on the inflatable device as hard as possible to rotate the handle to a position not less than90Degree, piercing through the membrane of the air bottle, high pressureCO2Gas is injected into the airbag, and when it expands, it generates buoyancy.

 Automatic version:After falling into the water, the life jacket's water-sensitive elements soften, allowing the pin to lose its blockage and the spring to stretch to push the needle through the airbag seal film.CO2Gas fills the airbag to create buoyancy.
