Tec 45 and Tec 45 Trimix

This is a course where you rise to the challenge and commit to becoming a technical diver. The PADI Tec 45 course extends your depth limit to 45 metres/150 feet. You will learn to plan and execute single and repetitive decompression dives using a single decompression cylinder with up to 100 percent oxygen. You will use double cylinders, which can be either back mount or sidemount diving configuration. Tec 45 is a prerequisite to Tec 50. There is also an option for divers to earn a Tec 45 Trimix Diver certification.

 

To enroll in the Tec 45 course, you must:
  • PADI Tec 40 Diver
  • PADI Rescue Diver (Proof of CPR/First Aid training within the previous two years required)
  • Minimum of 50 logged dives, with at least 10 dives deeper than 30 metres/100 feet
  • 18 years old

Tec 40 Trimix (option)

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.
