Free-diving (or freediving) is a form of underwater diving that relies on a diver's ability to hold his or her breath until resurfacing rather than on the use of a breathing apparatus such as scuba gear. Examples include breath-hold spear fishing, freedive photography, recreational breath-hold diving, apnea competitions, and to some degree, snorkeling. The activity that garners the most public attention is the extreme sport of competitive apnea in which competitors attempt to attain great depths, times, or distances on a single breath.
