Zeagle Surface Marker Buoy Deluxe Signal Tube, Fluorescent Orange & Neon Yellow

The Deluxe Signal Tube is a surface signaling device with its fluorescent orange and neon yellow coloring. A unique feature of the Deluxe Signal Tube 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 will enter the tube through a large Duck-bill valve at 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. This way a diver can signal he will soon be ready for pick-up, without going to the surface immediately. There is also an oral inflate valve for surface use.
