ABSTRACT:
A surface marker buoy apparatus is provided for use in diving and in particular for use in assisting a diver during his ascent. The apparatus includes an inflatable buoy which can be inflated when required to float and can be folded or rolled up when deflated. The buoy is secured to an anchoring device which defines a filling conduit for the buoy. The conduit has an ingress at one end and at its other end defines an aperture with a rim. A reel is provided which has a locking device that can be set to oppose rotation of the reel. A line, such as a conventional decompression line, is wound around the reel and attached directly or indirectly to the inflatable buoy at its free end. Preferably, the locking device is operated by a finger-catch deployed to unlock the reel by the diver using only one hand.
