TEC 40

Who should take this course?

The SDI 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 SDI 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 enrol in the Tec 40 course, you must be:

• A SDI Advanced Open Water Diver

• A SDI Enriched Air Diver with at least 10 dives using enriched air deeper than 18 metres/60 feet

• A SDI Deep Diver with 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 – ask your SDI Tec Deep Instructor.

​

What will you learn?

The Tec 40 course consists of three knowledge development sections, three practical application sessions and four training dives. You’ll learn about:

• Technical diving’s risks and responsibilities

• Technical diving equipment, proper rigging and set up

• Gas planning, oxygen limits and decompression planning

• Team diving techniques and emergency procedures, such as dealing with free flows, manifold leaks and out of gas situations

• ​

How can you start learning now?

Contact Ocean View Diving and get your Tec Deep Diver Crew-Pak that includes a SDI Tec Deep Diver Manual, which you can start reading right away. You can also get an Equipment Set-up and Key Skills video, which is a great tool to help you practice skills between your tec diving adventures. You’ll continue to use the Tec Deep Diver Crew-Pak through your Tec 45 and Tec 50 courses.

 

What scuba gear will you use?

You’ll start with your basic scuba diving equipment and add technical equipment, which essentially means you’ll begin to double up on gear. You may dive with back mounted or side mounted cylinders. Your SDI Tec Instructor may have you dive with EANx for additional conservatism.
