ABSTRACT:
An underwater-breathing device which combines the use of a snorkel with a scuba regulator to allow a skin diver to readily switch back and forth from the regulator to the snorkel as he alternates from deep diving to surfacing with his head submerged just a few inches below water surface, the breathing device comprising a two-way-selection valve having a mouthpiece formed therewith, and the valve being adapted to receive and connect to a scuba regulator at one point thereof and to a snorkel tube at a second point, whereby the diver can selectively employ either the scuba regulator or the snorkel by positioning the valve core within the valve housing.
