PADI Tec 40, Tec 45 and Tec 50, deeper? Longer?

 

Tec 40

The Tec 40 course introduces divers to limited decompression diving within accepted recreational depth limits.

Although the student who clearly intends to continue through Tec 50 is encouraged to complete Tec 40 in complete tec diving gear, the limits of the Tec 40 qualification allow more flexibility.

Therefore, to accommodate divers interested in very limited tec diving, the Tec 40 equipment requirements are only a bit beyond those of the standard recreational kit.

 

A Tec 40 diver is qualified to:

  • Use decompression software and dive computers to plan and make decompression dives with not 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.

The Tec 40 course consists of knowledge development, three practical application sessions, one confined or limited open water dive, two open water no stop dives (simulated decompression) and one open water decompression dive.

 

Tec 45

The Tec 45 course provides a transitional qualification while continuing to develop as a technical diver. The equipment requirements are the same as for the Tec Deep Diver Course.

This diver is qualified to make limited technical decompression dives using the equipment and the procedures used at the Tec Deep Diver level. However, qualifications are narrow, reflecting comparatively limited training and experience. The expectation is that a Tec 45 diver plans to continue on to Tec 50.

 

A Tec 45 diver is qualified to:

  • Make single and repetitive dives to a maximum depth of 45 metres/145 feet.
  • Use a single decompression gas of EANx, or oxygen, to accelerate or add conservatism to the decompression.

In addition to the Tec 40 course requirements, the Tec 45 course consists of knowledge development, three practical application sessions, one confined or limited open water dive, two open water no stop dives (simulated decompression) and one open water decompression dive.

 

Tec 50

The Tec 50 course is the complete, entry-level skill set for extensive open circuit deep decompression tec diving (formerly Tec Deep Diver). The diver is qualified to make technical decompression dives within the limits of training and equipment.

 

A Tec 50 is qualified to:

  • Use air, EANx and oxygen for multiple stop decompression dives as deep as 50 metres/165 feet using standard open circuit, multiple cylinder (backmount and/or sidemount) tec diving equipment.
  • Use two decompression gases (EANx and/or oxygen) to accelerate or add conservatism to the decompression.

In addition to the Tec 45 course requirements, the Tec 50 course consists of knowledge development, two practical application sessions, two open water no stop dives (simulated decompression) and two open water decompression dives.
