It is an underwater activity in which a person swims through the body of water by using a snorkel ( a diving mask equipped with a 40 cm long breathing tube) and swimfins. While one end of the snorkel is in the mouth, the other end sticks out of water, allowing snorkelers to breathe with their faces down in the water.
Snorkeling is a recreational activity than a professional sport. A snorkel may also be used in scuba diving, spear fishing, fin swimming and competitive underwater sports such as underwater hockey and underwater rugby.
It is a form of underwater activity in which a diver uses scuba set to breathe underwater to be able to navigate deep in the water. Scuba is the acronym for self-contained underwater breathing apparatus. A scuba set includes mask, snorkel, air tank, fins, protective diving suit, boots, gloves, pressure gauge, regulator and buoyancy compensator.
Scuba diving could be done recreationally or professionally. Professional scuba diving is done for scientific, military and research purposes. The difference between snorkeling and scuba diving is that a snorkeler swims with a snorkel to enable him to breathe through his mouth while floating underwater near the surface, and a scuba diver goes deep into the water by using scuba set.
