PADI Tec 40

PADI Tec 40, the Perfect Start to your Technical Diving Adventure.

If you’re interested in technical diving, PADI Tec 40 is the ideal starting point. It is the first sub-division of the full PADI Tec Deep Diver course and consists of theory work and the first 4 dives. Courses are run on a 2:1 student to instructor ratio to ensure you get the best attention and instruction.

You’ll learn to:

  • Set-up a twin-set rig with independent regulators and a dual-bladder wing.
  • Rig and use a stage cylinder for decompression gas.
  • 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.

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

The Scuba Gear You Will Use:

You could use recreational scuba equipment, with some minor additions to enhance your ability to deal with Tec Diving conditions. However, you will likely choose to use the same equipment configuration that you would use for Tec Diving and courses at Tec 45 and beyond.  We are able to supply all major items of equipment.

The Learning Materials You Will Need:

You’ll use the Tec Deep Diver Crew-Pak, which introduces you to:

  • Tec Diving Terminology & Emergency Procedures;
  • Decompression and stage cylinder handling;
  • Gas Planning;

You’ll continue to use the Tec Deep Diver Crew-Pak through to Tec 50.
