Freediving and scuba diving activities come with their risks and safety precautions. When it comes to safety, freediving is generally considered to be safer than scuba diving because of the lack of equipment involved. Freedivers rely on their breath-holding abilities and physical strength to stay underwater, while scuba divers use compressed air tanks for breathing underwater. This means that if something goes wrong with a diver's air supply while they are scuba diving, they could be in serious trouble.
