Lesson plan
Snuba
Snuba is form of surface-supplied diving that uses an underwater breathing system developed by Snuba International. The origin of the word "Snuba" may be a portmanteau of "snorkel" and "scuba", as it bridges the gap between the two. Alternatively, some have identified the term as an acronym for "Surface Nexus Underwater Breathing Apparatus", though this may be a backronym for the portmanteau. The swimmer uses swimfins, a diving mask, weights, and diving regulator as in scuba diving. Instead of coming from tanks strapped to the diver's back, air is supplied from long hoses connected to compressed air cylinders contained in a specially designed flotation device at the surface. Snuba often serves as a form of introductory diving, in the presence of a professionally trained guide, but does not require scuba certification.
