Hollis Surface Marker Buoy

The Hollis Surface Marker Buoy (SMB) has a self sealing opening to prevent gas escaping and the buoy from deflating on the surface.

An over-pressurisation valve allows excess gas to be vented automatically to prevent damage and also allows the diver to manually deflate the SMB.

A hose / oral inflator attachment allows the SMB to be inflated via a quick disconnect hose or manually inflated if required.
