Tec 40

The PADI Tec 40 course is where you transition from recreational scuba diving to technical diving. It’s a great place to start because it’s the first subdivision of the full PADI Tec Diver course and bridges the gap between no stop diving and full technical deep decompression diving. You gain experience and begin building the knowledge and skills you need to continue your tec diver training. You will qualify to make limited decompression dives to 40 metres/130 feet.

To enroll in the Tec 40 course, you must be:


You also need to have a  Diver Medical Form signed by a physician within the last 12 months.

The Tec 40 course consists of seven knowledge development sections, four practical application sessions and four training dives. You’ll learn about:

  • Technical diving risks and responsibilities
  • Technical diving equipment, dive equipment configuration, and use
  • Team diving and communication
  • Decompression and gas planning using dive planning software
  • Team diving techniques and emergency procedures to deal with free flows and out of gas situations
  • Thinking Like a Technical Diver
  • Handling Underwater Problems
  • Introduction to Trimix (for Tec 40 Trimix students)

Curious about the benefits of using Trimix gas, like decreased gas density and reduced narcosis? Tec 40 divers can also learn to use trimix with not less than 21 percent oxygen and not more than 35 percent helium. Ask your instructor what additional requirements you may need to complete the Tec 40 Trimix option.
