Black Self-sealing Surface Marker Buoy with DIN fitting inflation cylinder
Why black? It seems an odd choice, but in fact, in terms of visibility from sea-level, a solid black line is highly visible against both the sea and the sky in most daylight conditions. For this reason, many fisherman use black buoys and flags to mark their pots. It is also why the RAF have chosen black as the best colour to paint their training aircraft.
The SMBCi can be inflated from it's attached 0.1 litre mini-cylinder.
The SMBCi can also be inflated from a second stage air source. It can be inflated for the duration of the dive or used as a delayed-action deco buoy. A dump/over-pressure valve prevents over inflation and allows deflation after use.
The SMBCi will remain inflated out of water allowing it to be waved by the diver as a signal.
