ABSTRACT:
A dive accessory has an outer shell that encompasses a light maker and a noise maker. The light maker is waterproofed and has a light source electrically connected to an electrical power source for powering the light source. A light switch selectively opens and closes the electrical connection to switch the light source on and off. The noise maker has a hollow chamber containing a solid object that is movable within the hollow chamber to produce a noise when the solid object strikes a wall of the hollow chamber. The solid object may be restrained from moving to prevent the solid object from making noise. Combining a light maker and a noise maker provides a more effective dive accessory.
