The most common types of scuba diving include open circuit scuba, rebreather diving, and technical diving. Open circuit scuba is the most popular type of recreational diving, as it allows divers to breathe air from a tank while underwater. Rebreather diving uses a closed-circuit system that recycles exhaled gases back into the tank for re-use. Technical diving focuses on exploring caves, wreck diving, or other specialized environments.
