Patented surface marker buoy
The patent applies to a one-way valve that allows the surface marker buoy to remain inflated, even when it is lying on the water (wind, waves, slack cord, etc.). This means that the surface marker buoy remains inflated and operational. This valve acts as an overpressure valve: the surface marker is not damaged when returning to the surface.
