Freediving is diving underwater (usually in the ocean) without using a breathing apparatus (air carried in tanks on their backs or supplied through a hose). Free divers practice holding their breath for long periods of time so that they can stay underwater longer.
Usually free divers stay underwater for about 45 seconds. That allows them to explore about 30 feet underwater. Some freedivers can dive to over 100 metres (300 feet), and hold their breath for four minutes or longer. This is dangerous as if they cannot get back to the surface before thy use up the oxygen in thier breath they will pass out underwater and are then likely to drown.
Free diving equipment includes a mask, snorkel, fins, wetsuit and weightbelt.
Dangers of free diving include:
- becoming panicked
- passing out because of lack of oxygen
- possible death from drowning if you are not trained well and if you go too deep into the water
