Diver Below Flag Buoy

This high visibility Diver Below inflatable signal floater dive flag with red buoy ball has a padded valve cover. The unique feature of this Flag Buoy is that the diver can fill the tube at depth by holding the open bottom of the tube over a regulator mouthpiece while the regulator is being purged. The air enters the tube through a large duck-bill valve at the bottom. When the tube is sufficiently filled with air, the diver can release it to the surface while tied to a line. A built-in Over Pressure Relief Valve allows the tube to ascend without rupturing.
