I'd like to learn about the different types of scuba diving.

The most common type of scuba diving is called open circuit scuba diving, which uses a tank of compressed air that you breathe from. This type of dive is usually done in shallow waters and can be done with or without a buddy. Another type of scuba diving is called closed-circuit rebreather diving, which uses a breathing apparatus that recycles your exhaled gas for use again. This type of dive is usually done deeper than open circuit diving and requires more training and experience.
