What is it? Free Diving is a type of underwater diving that relies on a diver’s ability to hold his or her breath until resurfacing rather than the use of a breathing apparatus. Competitors have the option to dive for depth or time on a single breath. The sport is governed by two international bodies and has a multitude of disciplines available to compete in including fin, free, weighted or team. The current world record holder is Herbert Nitsch who has attained a depth of 214 meters (702 feet).
