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.

Course Goals

The DSAT Tec 50 will further develop skills learned in the Tec 45 stage of training to extend divers abilities. The program will focus on expended decompression planning and the use of 2 stage/deco bottles. Successful students will be able to plan dives utilizing one stage and one deco bottle or two deco bottles.


  1. Certified as a Tec 45 diver or provide a qualifying certification from another training organization. For the purposes of this level, a qualifying technical certification is one that qualifies the student to make decompression dives to 45 metres/145 feet using air, EANx and oxygen using open circuit, double cylinder scuba equipment (sidemount or backmount).
  2. Certified as a PADI Rescue Diver or provide a qualifying certification from another training organization. For this course a qualifying certification is proof of training in diver rescue. Students who meet this prerequisite through a qualifying certification must provide proof of training in CPR and First Aid within the previous two years.
  3. Minimum age: 18 years.
  4. Have a minimum of 100 logged dives, of which at least 20 dives were made with enriched air nitrox deeper than 18 metres/60 feet, and at least 15 (with or without EANx) dives were deeper than 30 metres/100 feet.
