The Atlantis Duckbill SMB is inflated by purging a regulator into the open end of the buoy. The unique self-closing duckbill valve forms an airtight seal immediately on inflation, preventing the buoy from accidentally deflating on the surface.There is also an oral inflation valve which allows the buoy to be blown up manually and also allows controlled deflation of the buoy without using the dump valve.
