Tec 50

Tec divers doing NOTOX gas switchThe third part of the full PADI Tec Deep Diver program is Tec 50. As a Tec 50 diver, you show that you’ve developed competency as a tec diver and have the skills to dive to a maximum of 50 metres/165 feet. You know how to make extended, accelerated decompression stops using up to two gases. It’s not easy to reach this level and earning your Tec 50 certification opens the door to deeper diving expeditions.

What you will learn

The Tec 50 course includes two knowledge development sections, three practical application sessions and four open water dives. A primary focus of this course is mission planning and execution. You also learn more about handling emergencies and how to think like a technical diver.

  • PADI Tec 45 Diver

The Tec 50 course, as the third part of the Tec Deep course, consists of 4 open water dives.
