Building A Foundation For Tec Diving

The PADI Tec 40 Diver class is in many ways the “open water” of technical diving. Your instructor will cover many of the basic concepts of technical diving including dive planning, team diving techniques, equipment configuration and skills and emergency management. As you progress deeper through the PADI Tec 45, Tec 50, Tec 65 Trimix and Tec Trimix classes, you build on the basic skills you learned in this class.
