Tec 45

The PADI Tec 45 course is the second part of the full PADI Tec Deep Diver program. You’ll extend your depth limit to 45 metres/145 feet and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.

To enroll in the Tec 45 course, you must:

  • Be a PADI Tec 40 diver
  • Be a Padi Rescue diver, proof of CPR/First Aid training within the previous two years.
  • Have a minimum of 50 logged dives, with at least 12 dives on enriched air nitrox deeper than 18 metres/60 feet and 6 dives deeper than 30 metres/100 feet
  • Be at least 18 years old
  • Have a  Diver Medical Form signed by a physician within the last 12 months


Your Tec 45 training consists of seven knowledge development sections, four practical application sessions and four open water dives. Building on what you learned in the Tec 40 course, you will focus on additional techniques, procedures, and emergency skills. You will learn more advanced decompression, gas planning, decompression models, and fine-tune your thinking like a technical diver. Tec 45 Trimix students will also learn about diving trimix.


Curious about the benefits of using Trimix gas, like decreased gas density and reduced narcosis? Tec 45 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 for the Tec 45 Trimix option.
