There are several different types of scuba diving, including recreational diving, technical diving, cave diving and freediving. Recreational diving is done for fun and exploration, while technical diving involves more advanced techniques such as decompression diving and underwater welding. Cave diving is a specialized form of diving that takes place in caves or other underwater environments where visibility can be limited. Freediving is an extreme sport which involves swimming below the surface without breathing apparatus.
