An underwater diving marker is disclosed which has a tube with at least one removable end. A strap element extends between the removable end and the housing and is folding or otherwise compressed to fit within the housing. The end cap has a positive buoyancy so it will float when separated from the housing even with being attached to the strap. The housing includes a weight element which insures that the housing has a negative buoyancy when separated from the end cap. The user removes the end cap and allows it to float up pulling the strap/tether, while the housing sinks to the sea floor, thereby providing an indicator flag to divers.
