ABSTRACT:
A front-mounted swimming snorkel with separate air intake and exhaust tubes controlled by one-way valves to prevent re-breathing exhaled air, wherein the exhaust tube cross-sectional area is selected to regulate the amount of force needed to open the water purge valve so that a swimmer can open the purge valve by exhaling with more force than normal.
