Tec Basics course

Tec Basics is a multi-use course that focuses on orientation to new dive equipment, technical diving skills, and techniques. It is an optional level that can help divers explore new equipment configurations and refine their foundational skills before moving on to Tec 40 Diver.

To enroll in the Tec Basics course, you must meet these qualifications:

PADI Advanced Open Water Diver, and PADI Rescue Diver recommended
PADI Enriched Air Diver
15 years old

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.

Tec 40 course

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.

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 or proof of 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.

Tec 45 course

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
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 Medical Statement signed by a physician within the last 12 months

Tec 50 course

The third part of the full PADI Tec Deep Diver program is Tec 50. As a Tec 50 diver, you show that you’ve developed competency as a tec diver and have the skills to dive to a maximum of 50 metres/165 feet. You know how to make extended, accelerated decompression stops using up to two gases. It’s not easy to reach this level and earning your Tec 50 certification opens the door to deeper diving expeditions.

To enroll in the Tec 50 course, you must:

Be a PADI Tec 45 diver
Have a minimum of 100 logged dives, with at least 20 dives on enriched air nitrox deeper than 18 metres/60 feet and 15 dives deeper than 30 metres/100 feet
Be at least 18 years old
Have a Medical Statement signed by a physician within the last 12 months

Tec Sidemount Diver course

If you’ve looked into technical diving, you realize that tec divers always wear more than one tank. Sidemount is an increasingly popular way to configure multiple cylinders for technical diving. You can enter the world of tec diving with the Tec Sidemount Diver course and apply what you learn to other TecRec courses. You can integrate this course with the Tec40/45/50/65/Trimix courses.

If you’re a PADI Advanced Open Water Diver, at least 18 years old and have a minimum of 30 logged dives, you qualify to enroll in a Tec Sidemount Diver course. It’s recommended that you also have a PADI Enriched Air Diver certification.

Tec Trimix Diver course

Ready for the outer edge of technical diving? The Tec Trimix Diver course takes experienced tec divers and turns them into extreme divers who go deeper and visit pristine sites where few others will ever go. During the course, you’ll make dives as deep as 90 metres/300 feet, but once you earn this tough certification, there are few limits. Your training teaches you to build experience gradually and you do it because you’ve made it this far and have more exploring to do.

To enroll in the Tec Trimix Diver course, you must:

be a PADI Tec 50 diver or Tec Trimix 65 diver
have a minimum of 150 logged dives
be at least 18 years old
have a Medical Statement signed by a physician within the last 12 months
