Abstract
A diver's signal flag which is pivotally attached to the diver's belt or other portion of his equipment and protrudes above the water when the diver is at or just below the surface to indicate the presence of the diver to passing boats, other divers or rescue crews. The pivotal mounting allows the flag supporting mast to deflect when passing under kelp or similar obstructions. In a preferred form of the apparatus the flag mast is balanced by a pendulum weight to remain vertical and projects above the water regardless of the attitude of the diver. When submerged the flag remains erect and provides the diver with high visibility to other divers.
