Orienteering is an outdoor sport that involves navigating through unfamiliar terrain using a map and a compass. However, underwater orienteering is a unique twist to the traditional sport that takes place in the underwater environment. It requires scuba diving skills and the ability to read underwater maps. Some synonyms for underwater orienteering are aquatic orienteering, scuba orienteering, dive orienteering, and subaquatic orienteering. This sport is not only a fun and challenging activity but also helps improve diving skills and teaches participants to read underwater maps, which can come in handy during underwater adventures like exploring shipwrecks or underwater caves.
