ABSTRACT:
A dive mask of the purge valve-type that comprises a deflector affixed to the lower front surface thereof for channeling air bubbles expelled during purging to the sides of the mask to avoid interference with the diver's vision. A plurality of vertical and horizontal spacers are also provided to assure the availability of a free flow air channel between the deflector and the remaining structure of the mask. In the preferred embodiment disclosed herein, the deflector is ornamentally shaped to enhance the styling and physical appearance of the overall mask structure.
