Tec 40


PADI Tec 40 – When One Tank Is Not Enough

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.

If you’re interested in technical diving, but haven’t yet met the prerequisites for the PADI Tec 50 or Tec Deep Diver course or the PADI Tec 45 course, your first step is enrolling in the PADI Tec 40 course. 

It is the first subdivision of the full PADI Tec Deep Diver course and consists of the first four dives. The PADI Tec Deep program is built upon three new courses: Tec 40, Tec 45, and Tec 50. This new course breakdown allows the technical decompression diving program to be diver friendly, letting the student built their experience gradually.

Each level of certification in the Tec Deep program allows the successful candidate to gain experience and still enjoy the benefits of decompression.

The Tec 40 course is the perfect entry point into the technical field of technical diving and provides a smooth transition from recreational diving. Upon completion the successful candidate will be qualified to complete up to 10 minutes of non-accelerated decompression while breathing from one additional deco cylinder of up to EANx50. Remember since it’s part of the course, this experience will be credited toward your Tec 45, Tec 50 and or full Tec Deep.

To Enroll In The Tec 40 Course, You Must Be:

  • A PADI Advanced Open Water Diver
  • A PADI Enriched Air Diver with at least 10 dives using enriched air deeper than 18 metres/60 feet
  • A PADI Deep Diver with at least 10 dives to 30 metres/100 feet
  • At least 18 years old and have a minimum of 30 logged dives
  • You also need to have a Medical Statement signed by a physician within the last 12 months. 
 Note that qualifying certifications from other diver training organizations may apply – ask your PADI Tec Deep Instructor.

  • Technical diving’s risks and responsibilities
  • Technical diving equipment, proper rigging and set up
  • Gas planning, oxygen limits and decompression planning
  • Team diving techniques and emergency procedures, such as dealing with free flows, manifold leaks and out of gas situations
