The 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.

The Training

The PADI TEC 50 course includes three parts: 

  • Knowledge Development – Once you have signed up for the course, we will provide you with a digital CD manual to read and complete the relevant knowledge reviews before your practical training. Your instructor will then review this and go into further detail in the classroom covering topics such as:
    • Accelerated decompression planning using multiple decompression gases
    • Procedures for handling multiple enriched air gases 
    • Stage preparation and labelling
    • Emergency procedures
  • Confined Water Training – After all the gear is set up, it’s time to get wet! Starting in a calm shallow water environment, your instructor will spend time going through emergency shutdown drills, simulated decompression plans and equipment configuration.
  • Open Water Dives – Over the course of 2 days you will then complete 3 additional dives in 3 tank configuration repeating the skills from confined water to make them fluid whilst progressing to more complex decompression plans. Your qualifying dive will be completed at the Zenobia wreck up to a maximum of 50 metres. You will also cover the following skills and drills within your training:
    • Wrong gas switch drills
    • Gas switching and staging multiple gas procedures
    • Accelerated decompression plans and using multi-gas computers
    • Use of air breaks within a decompression plan


    • Age: 18 years old and above
    • PADI TEC 45 Diver and above, or equivalent, from an alternative agency
