Tec 45 and Tec 45 Trimix
About the Course
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 meet these qualifications:
- 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
You also need to have a Download the Diver Medical Participant Questionnaire signed by a physician within the last 12 months.
Note that some qualifying certifications from other diver training organizations may apply - ask your Tec 45 Instructor.
Getting Started
Contact your PADI Dive Center or Resort, and if you don't already have one, pick up a Tec 45 Diver Crew-Pak that includes PADI Tec 45 Diver eLearning which you'll study independently before meeting with your PADI Tec 45 Instructor.
You may be able to get college credit for the PADI Tec 45 course.
Academic
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.
Equipment
You'll dive Air or EANx, including up to 50 percent enriched air for decompression. If you’re taking the Tec 40 Trimix Diver course you’ll also use trimix.
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.
