Different types of Scuba are split depending on the breathing devices employed in the dip.

In open-circuit scuba, the atmosphere is provided by a tank or other origin, and after inhaled, is exhaled into the surrounding water. It's by far the most frequent kind of scuba utilized for diversion.

In closed circuit scuba, the atmosphere is recycled although using apparatus known as rebreathers, and oxygen is reintroduced to the air source of the retina via an apparatus. 

In semi closed-circuit scuba, combined gases are utilized as the air source, taking a portion of the atmosphere exhaled by the diver in addition to adding to it using an air source very similar to that utilized in open circuit scuba.

Semi closed-circuit ski is more challenging to learn than closed or open circuit scuba diving independently, as it entails knowledge from the two kinds of diving since the breathing device used is a combination of both.
