PADI Tec 50 Course $999

The PADI Tec 50 course is the final stage of the PADI Tec Deep Course. 

As a Tec 50 Diver you will show that you have developed competency as a tec diver and have the skills to dive to a maximum of 50m. You know how to safely and successfully make extended, accelerated decompression stops using up to two stage bottle with TWO different EANx gases up to 100% O2.

It’s not easy to reach this level and earning your Tec 50 certification opens the door to deeper diving expeditions.


Successful candidates will not only be qualified to conduct decompression dives to a max depth of 50m, but more importantly, the course builds on skills learnt on the previous courses, so you will be comfortable using twins, but now will be managing TWO stage decompression gases.  You can then begin the PADI Tec65 - Trimix course

  • Deep Diver qualification with a minimum of 15 dives deeper than 30m
