Our closed surface marker buoy is made out of a hard-wearing light and gas-tight nylon material. The edges are ultrasonically welded. To further protect the seams the edges are trimmed with a nylon ribbon.
The surface marker buoy is filled through a Schrader valve on a short tube, either from an inflator hose or orally. The buoy is protected from over-filling by an over pressure relief valve (OPRV) next to the Schrader valve. The OPRV is also used to empty the buoy.
