Diving sites and scuba centers in Brazil
The biggest difference between skin and scuba diving is air.
Skin divers are limited to how long they can stay underwater by the amount of air they can hold in their lungs. Scuba divers carry their air supply with them. Scuba actually stands for self-contained underwater breathing apparatus.
Skin diving is also referred to as free diving, breath hold diving, or sometimes snorkeling. Skin divers often use a face mask to see more clearly underwater, along with fins for propulsion and snorkel for breathing.
