What is SNUBA?

SNUBA is a cross between snorkeling and scuba diving; it features a simple-to-use regulator and long hose that users breathe through, which connects to an air supply that floats on the surface raft. This setup allows individuals to dive down to depths of 20 feet to enjoy a three-dimensional underwater world without heavy, cumbersome air tanks, or need to come up to the surface for a breath of air. 1.
