Technical Diving
Definition
Technical diving goes beyond recreational limits, often involving decompression, mixed gases, and advanced equipment.
More on Technical Diving
Technical diving (or tec diving) includes activities such as deep dives beyond 130 feet (40 meters), use of gases like trimix or heliox, staged decompression, and penetration into overhead environments like caves or wrecks. Tec diving requires specialized training, redundant gear, and meticulous planning. Divers often carry multiple tanks, backup regulators, and redundant computers. It's rewarding but risky, demanding discipline, precision, and continual education.
Frequently Asked Questions
Any dive beyond recreational depth/time limits, involving staged decompression, gas switching, or overhead environments.
Courses such as Advanced Nitrox, Decompression Procedures, and Trimix are common entry points.
Decompression sickness, oxygen toxicity, narcosis, gas mix errors, and equipment failures require rigorous preparation.
No, many experienced recreational divers pursue tec diving as a hobby—though it demands serious commitment.
Twinsets, stage/deco cylinders, redundant computers, long hoses, and often drysuits for thermal protection.
