Technical divers may face lengthy decompression obligations. A technical team needs to maintain adequate gas reserves to get two divers safely to the surface from the deepest point of the dive. In the event one diver experiences a catastrophic loss of gas, they must be able to ascend at the exact same speed while sharing gas in a horizontal position and hold their decompression stops without the use of a line. In a worst case scenario, they need to be able to maintain precise control while managing multiple failures simultaneously. Both common and uncommon equipment failures must be handled with skill, speed, and precision on the move. This is what we begin training for during our introduction to technical diving training and we progressively build more complex scenarios and greater demand for proficiency as the depths and bottom times increase.

Technical diving has traditionally been defined as:
1. Diving below the maximum recommended sport diving limit of 130 feet.
2. The use of gas mixtures other than air such as nitrox or trimix.
3. Dives involving mandatory stage decompression stops, especially those involving the use of gas switches to accelerate decompression.
4. Cave or wreck penetration.
5. The use of advanced equipment such as stage bottles, decompression bottles, and rebreathers.
PSAI was the very first technical training agency in the USA established in Florida in 1962. Deep diving expertise in wreck and cave diving is the cornerstone of the organization. It is our recommendation that recreational sport divers cap their dives at 90 feet and seek proper instruction in extended range air, nitrox, and trimix diving beginning at 100 feet due to the need for correct gas management and gas sharing skills.
