Abstract : The patent relates to a bidirectional day-night marine location marker means which floats includes two frangible cylinders each containing a plastic bag, one loaded with an oxyluminescent material and the other loaded with a dye material. Each cylinder is mounted in facing relation to each other on a wooden block and a firing mechanism is seated there-between which when activated causes rupture of the caps and subsequent expulsion of the material in the two plastic bags in opposite directions spreading their contents on the water. The remainder of the marker body sinks.
