TEC 40 The first step of the PADI Tec Deep Diver course

The PADI Tec 40 Course

If you’ve heard of tec diving and feel you want to give it a go without going stupidly deep or carry all that gear – this is for you. It is the first subdivision of the full PADI Tec Deep Diver course and consists of the first four dives. The prerequisites are easily met and there is no great change in gear. The course WILL change your attitude toward diving though!! The Tec 40 is also the first subdivision into the full PADI Tec Deep course which means if you like it, you can carry on!

What you’ll be doing

Use decompression software and dive computers to plan and make decompression dives with no more than 10 minutes of total decompression and not deeper than 40 meters/ 130 feet.

Use a single cylinder of decompression gas with up to 50 percent oxygen (EANx50) to add conservatism to the required decompression.

Since it's part of the course, your PADI Tec 40 course training credits toward the PADI Tec 45 and PADI Tec 50 courses.

What you will learn

You'll use the Tec Deep Diver Crew-Pack, which introduces you to:

  • Differences between Tec and recreational diving
  • Gear Configuration - equipment
  • Decompression and stage cylinder handling
  • Gas planning
  • Emergency procedures

The pack includes a manual, dive planning checklist and dive planning slate. The optional Equipment Set-up and Key Skills video on DVD is a great tool to help you practice at home in between your tec diving adventures. You'll continue to use the Tec Deep Diver Crew-Pak through Tec 50.
