Tec 40 Course


Tec 40


This program goes beyond recreational diving, immersing you in the realm of technical diving. If you have an interest in technical diving but haven’t fulfilled the requirements for the Tec 45 Diver course, you may consider enrolling in the Tec 40 course. This course serves as the initial stage of the complete Tec Deep Diver course, involving the first four dives and accommodating side-mount if necessary.

Participants will gain knowledge in equipment rigging, gas planning, team diving, technical hand signals, gas shutdown drills, gas switching, long hose gas sharing, lift bag deployment, use of deco cylinders, equipment and gas failure procedures, diver emergencies and rescue drills, oxygen management, deco computer software, and executing deco stops.
