ABSTRACT OF THE DISCLOSURE An improvement in buoyant marine devices, such as pyrotechnic markers, the displacement of which normally decreases during operation as a result of weight loss. The device is provided with a ballast means and means to enable the ballast compartment to fill progressively with water whereby, during operation, displacement of water by the marker is maintained to a degree which will ensure that the device remains in operative orientation. In this way, the problem of tilting by marine markers because of a gradual decrease in weight, to the point that the marker may be easily submerged by water and its operation thereby hampered, is significantly reduced.
