Technical diving, or "tech diving," extends beyond recreational diving limits through advanced techniques and specialized equipment. Divers often use mixed gases like nitrox, trimix, or heliox to safely dive deeper and for longer periods, reducing risks like decompression sickness and nitrogen narcosis. Unlike recreational diving, which typically limits depths to 40 meters (130 feet), tech diving often involves exploring challenging environments such as caves or wrecks.

Key to tech diving is meticulous planning and the use of multiple gas sources for safety. Divers carry redundant systems, including extra regulators and dive computers, adhering to a streamlined equipment setup to enhance mobility. Decompression procedures are central to tech diving, involving calculated ascent plans with mandatory decompression stops.

Training for technical diving is rigorous, focusing on advanced buoyancy control, precise navigation, and problem-solving under pressure. This preparation is crucial for managing the psychological and physiological challenges of deeper, longer dives. Ultimately, technical diving expands divers' capabilities to explore underwater environments beyond recreational limits, emphasizing safety and risk management.
