Portable diver distress signalling device

摘要

A diver distress signalling device that has two separable dye containing elements. The device is strapped to a diver and includes an actuating mechanism. Upon actuation, the dye from one of the elements is released in the vicinity of the diver, while a float carries the other dye container to the water surface, streaming a trail of dye behind it. At the surface, dye is emitted to color the water in the vicinity of the float.
