Scuba Diving International (SDI) Computer Nitrox Practice Exam

What does the term technical diving refer to?

1. A type of recreational diving that goes beyond sport diving limits

2. Deep sea diving without any restrictions

3. Free diving without the use of tanks

4. Any diving activity that occurs in cold water

The correct answer is: A type of recreational diving that goes beyond sport diving limits

The term technical diving refers to a type of recreational diving that goes beyond sport diving limits. This includes various practices and techniques that extend the depth, duration, and complexity of scuba diving beyond the traditional recreational limits. Technical diving often involves the use of special gas mixtures, such as trimix or nitrox, to mitigate the risks associated with deeper dives. It requires specialized training and equipment, as divers may engage in activities like diving to deeper depths, performing decompression stops, or diving in environments that require advanced skills, such as wreck or cave diving. The nuances of technical diving make it distinct from recreational diving, which typically adheres to defined limits concerning depth and nitrogen exposure.
