What is free scuba diving?
Freediving is a globally practiced form of underwater diving relying on breath-holding until resurfacing. Instead of using a breathing apparatus such as scuba or a tankless dive system, freedivers rely solely on the air in their lungs to power their bodies below the surface. Freediving is a sport performed in extreme environments and, if undertaken by inexperienced, untrained, or competition divers, can lead to severe injury or even death. However, the risk of damage can be reduced by performing it responsibly with the appropriate training and by using proper safety measures.Freediving requires you to hold your breath underwater (this is the most obvious difference). Scuba diving allows you to breathe underwater, without needing to come to the surface. Freediving requires less equipment, making it more convenient when traveling light.
