Tec 40

If you're interested in technical diving, but haven't yet met the prerequisites for the Tec 50 course, you can consider enrolling in the DSAT Tec 40. It is the first rung in the Tec Deep ladder, the first subdivision of the full PADI Tec Deep Diver course consists of the first four dives.

Because you can do one of these dives in confined water (such as a swimming pool), many divers start the Tec 40 courses in the winter months, ready to continue in open water when spring arrives. You will learn to 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 metres/130 feet.

Most people learn technical diving in backmount (both cylinders located on back), if you want to take this course and in sidemount (one cylinder located separately under each arm) and find out why side mount configuration is superior.

What do I need to start?

You use recreational scuba equipment, with some minor additions to enhance your ability to deal with tec diving conditions. Tec Deep Student Crew-Pak, which includes student manual, planning slate and checklist slate (need a few weeks before the start of the Course to allow you time to complete all Knowledge Reviews etc).

What will I do?

You'll learn to:

- 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 metres/130 feet.
- Use a single cylinder of decompression gas with up to 50 percent oxygen (EANx50) to add conservatism to the required decompression.
