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.


The beginning tech class is where we start transitioning you from a recreational diver to thinking in a more technical way.

What is a technical diver? A technical diver is simply one with the knowledge to plan and execute a dive beyond recreational limits. I observe too many divers that dive until they are low on air and then surface. That’s not the proper or safe way to dive at any level. There is a big difference between surviving the dive, and executing the dive using knowledge and skills. It doesn’t have to be deep, dark, and scary. In fact, with proper training it’s quite the opposite. This beginning tech class is a large knowledge gain for recreational divers, a giant skill improvement, and a perfect opportunity to learn more about technical diving.

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

    • An advanced open water diver
    • Nitrox diver – with at least 10 nitrox dives
    • Deep diver – with at least 10 deep dives
    • At least 18 years old
    • Minimum of 30 logged dives
    • Must be able to hover +/- 3ft with minimum sculling/fin kicking

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.

A note to the prerequisites above, these are the bare minimum. The course is a large amount of work for even experienced divers.

My favorite part of this class is once the students go back to dive with their normal dive buddies. This is when they realize how large of an improvement they made during the class.


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

  • 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


You’ll start with your basic scuba diving equipment and add technical equipment, which essentially means you’ll begin to double up on gear. You may dive with backmounted or sidemounted cylinders.

I have a detailed list of all the equipment needed. Please contact me and I’ll send it to you.
