Course Description

The PADI Tec 40 course is the first subdivision of the full PADI Tec Deep Diver course and consists of the first four dives. 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 and to 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 Tec Deep Diver course, your PADI Tec 40 course training credits toward the PADI Tec 45 and Tec 50 courses.

You may use your recreational scuba equipment, with some minor additions to enhance your ability to deal with Tec diving conditions.

The PADI Tec 40 course is conducted over three days.
