What is the difference between scuba diving and skin diving?
The term SCUBA is an acronym for Self Contained Underwater Breathing Apparatus. The scuba diver carries his air supply with him in a high-pressure tank and is free to swim underwater without air supply lines to the surface. Skin Diving is a term sometimes used to describe surface swimming and frequent dives to depth with fins, mask, and snorkel. Other terms that describe this activity are Snorkeling, Free Diving and Breath Hold Diving.
