PADI Tec 40

Tec Dive to 130' Using One Decompression Gas Up to 50% EANx

PADI Tec Course Breakdown:

The PADI Tec Rec Courses are structured to build upon the skills of the previous class. The progression of classes are:


This allows the diver to take baby steps throughout their Open Circuit Technical Diving Courses. There is no bigger concern than task loading a diver with too many skills and variables to early on throughout their course. The PADI Tec Courses will ensure the diver is 100% comfortable with each step along the way of becoming a proficient technical diver.

Tec 40 Objective:

  • To introduce divers to limited decompression diving within accepted recreational limits.

  • To train the diver to prepare for and respond to reasonably foreseeable emergencies that may occur within Tec 40 limits.

Tec 40 Diver is Qualified to:

  • Use decompression software and dive computers to plan and make decompression dives with up to 10 minutes of total decompression and not deeper than 130'.

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