The Scubapro Surface Marker Buoy 210D Nylon is a professional grade SMB (surface marker buoy) that features a double inflation system with an open bottom - featuring a one-way duck beak valve, as well as a metal inflator. Commonly known as Semi Closed to some divers.

The gas cannot escape from the SMB once it gets inside, therefore no gas spillage when the SMB is at the surface. 

The buoy is constructed of durable 210D nylon with HF welded seams. There is a stainless D-ring and bungee loop on the lower end, with a plastic D-ring on top for a flashlight.

140cm will be available in both Orange and Yellow, whereas 180cm will only be available in Orange.
