The Tec 40 Diver Course is designed to teach you how to respond to emergencies while diving. The course includes three training diving sessions, a confined-water dive, knowledge development sessions, and practical applications. This certification can only be obtained after you have completed at minimum 30 dives. Upon completion of this course, you'll be eligible to take Padi Tec 40 courses at colleges and universities worldwide.
Tec 40 course
The PADI Tec 40 course extends the skills of recreational divers to include advanced techniques. This course introduces students both to air compression and trimix 65. It also teaches advanced skills in tec deep diving. Students of Tec 40 will learn how to use backgas and master buoyancy control. They will also learn advanced nitrox theory.
The Tec40 course emphasizes team diving techniques, self-reliance and communication in water. Decompression theory is also taught to students, which makes it easier to plan dives. The course also covers the best practices and equipment configuration for recreational divers.

The PADI Tec40 course takes around three days. Students must have at least 30 dives logged, 10 of which in enriched water, to complete the course. Students can switch to enriched air and dive up to 40m after completing the course.
Requirements to take Tec 40 course
If you are interested in technical diving, the PADI Tec 40 course is a great place to start. This course bridges recreational diving with technical deep-decompression diving. It provides the necessary skills for tec diver training. You will be able to decompress to 40m without stopping. You'll be able also to use a full-technical rig.
Students learn advanced decompression theory in the Tec40 course. However, it also emphasizes team-diving techniques and a self-reliant approach to the water. Tec40 introduces students to advanced nitrox theory including partial-pressures as well as oxygen exposure over multiple dives.
College credit for Tec40 course
PADI Tec40 is a three-day course that requires at least 30 logged dives. It also requires 10 enriched nitrox diving. It teaches divers how they can plan their dives and how to use oxygen and enhanced air to decompress. It also shows the diver how long to decompress and plan. This is the next step of a diver's diving training and opens up the doors to deeper expeditions. For those who complete the course, they can get college credit.

The Tec 40 course is designed for advanced divers who wish to increase their knowledge in technical diving. The course includes planning, using two deco gases (nitrox and 100% oxygen in stages), and navigating the multi-gas computer. This course is for those divers who have completed the PADI Advanced Open Water Diver Course and have at least thirty dives.
