Technical diving refers to advanced forms of scuba diving that go beyond the limits of recreational diving. It involves using specialized equipment, such as multiple tanks, mixed gases, and advanced diving tools, to explore deeper or more complex environments like wrecks, caves, or deep-sea areas. Technical divers often need to follow strict safety procedures due to the increased risks of deep dives, extended time underwater, and the use of different gases to avoid nitrogen narcosis or oxygen toxicity. This type of diving requires extensive training and knowledge of dive planning, navigation, and emergency protocols.
