Bobbins are a replacement part for the Halkey-Roberts type automatic inflators. Bobbins dissolve when immersed in water and cause the CO² cylinder to inflate the PFD. All Mustang Survival automatic inflatable PFD's come with cylinders and bobbins.
*For recreational use, bobbins should be replaced every three years to avoid inadvertent inflation.
