Technical Diving

Looking to dive deeper, longer, or with an overhead environment?  Technical diving opens up the exploration of wrecks, caves, and dives deeper than 130' and longer than your No Decompression Limitations!

Intro to Tec

Double your gas reserves with twin back mount cylinders on the TDI Intro to Tec Diver Course. Back Mount Diving is popular with Cave Divers and Wreck Divers requiring a greater gas supply than a single tank. This is an excellent course to have under your belt before entering Decompression Procedures or our combination courses.

Tec 40 - Advanced Nitrox

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.

Tec 50 - Extended Range

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.

Tec Sidemount

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. Your instructor may offer to integrate this course with the Tec 40, Tec 45 or Tec 50 courses.

Tec 45 - Deco Procedures

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.

Tec Trimix Gas Blender

The Tec Gas Blender course includes three practical application sessions, but no dives. During independent study and instructor-led review, you learn: About the advantages and disadvantages of different blending methodologies. To blend enriched air and trimix blends to within one percent of the target mix.
