The Airsource Adapter Ring allows you to mount the Airsource breathable inflator to BCs built by Mares, Scubapro and Zeagle. Just because someone has chosen not to dive with the world's best selling brand of buoyancy compensator does not mean that they should be deprived of the best performing breathable inflator. Ditch the standard inflator and octopus and decrease the number of hoses and drag by adding an Airsource to your rig.
