The main difference between a scuba diver and a free diver is that a scuba diver uses a compressed air tank to supply breathing gas, while a free diver relies on natural sources such as the air in the water or their own breath. Scuba divers also have more equipment, including a regulator and buoyancy control device, which help them stay underwater longer. Free divers usually only need fins, mask, snorkel, and a wet suit.
