The PADI Tec 45 course is the second part of the full PADI Tec Deep Diver program. You’ll extend your depth limit to 45 metres/145 feet and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.

Course Goals

The DSAT Tec 45 will further develop skills learned in the Tec 40 stage of training to extend divers abilities.  Successful students will be qualified to complete accelerated decompression divers using one decompression cylinder with O2 blends up to 100% O2 to a maximum depth of 145 ft / 45 m


  1. Certified as a Tec 40 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 limited decompression dives to 40 metres/130 feet using air and EANx using open circuit 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 50 logged dives, of which at least 12 dives were made with enriched air nitrox deeper than 18 metres/60 feet, and at least 6 (with or without EANx) dives were deeper than 30 metres/100 feet.
