Freediving, free-diving, or free diving is a form of underwater diving that relies on divers' ability to hold their breath until resurfacing rather than on the use of a breathing apparatus such as scuba gear. Recognised examples of freediving activities include traditional fishing techniques, competitive and non-competitive freediving, competitive and non-competitive spearfishing and freediving photography, synchronized swimming, underwater football, underwater rugby,^[1] underwater hockey,^[2] underwater hunting other than spearfishing, underwater target shooting and snorkeling. The term 'freediving' is often associated with competitive breath-hold diving or competitive apnea. However, while some regard freediving as a specific group of underwater activities, for others it is merely a synonym for breath-hold diving. The activity that attracts 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.
