Tec 40

If you’re interested in technical diving, but haven’t yet met the prerequisites for the PADI Tec 50 Diver course or PADI Tec 45 course, you can consider enrolling in the PADI Tec 40 course. It is the first subdivision of the full PADI Tec Deep Diver course and 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’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. You’ll 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 Tec 50 courses.

The scuba gear you’ll use: Standardised technical diving rig, including backplate, wing, twin tanks, additional regulators and stage cylinder.  You’ll learn more about this on the course.

The learning materials you’ll need:

You’ll also be given a Tec Diving Planning and Checklist slate to use on the course and beyond.
