Use: This is the standard all-purpose sea marker for daylight use: to provide reference points; to aid in determining drift; and to provide practice bombing targets on water.

Description: This marker consists of a paper composition case filled with a fluorescein dye. It is protected by a cylinder of papier-mâché, which does not interfere with its function.

Launching: The marker is dropped by hand from a plane.

Operation: Upon impact with water, the case shatters and the dye spreads upon the surface.
