Technical divers are specialized scuba divers who go beyond the limits of recreational diving. They use advanced techniques and equipment to explore deeper waters, often reaching depths of over 130 feet. This type of diving requires extensive training in areas such as decompression procedures, gas management, and emergency protocols. To ensure safety, technical divers often use multiple gas mixtures, including nitrox and trimix, which help reduce the risks of narcosis and oxygen toxicity. They also carry additional equipment like rebreathers and safety balloons to assist in their dives. Overall, technical diving is a complex and demanding activity that requires a high level of skill and knowledge.
