High Quality Content by WIKIPEDIA articles! Snuba is an underwater breathing system developed by Snuba International. The word Snuba is a portmanteau of "snorkel" and "scuba". The swimmer uses swimfins, a diving mask, weights, and diving regulator as in scuba diving. The air, however, instead of coming from tanks strapped to the diver`s back, comes through a long hose from tanks on pontoon rafts on the surface. Snuba often serves as a form of introductory diving, in the presence of a professional, insured guide, and following a half-hour lesson (but not requiring scuba certification).
