PADI Tec 45

The PADI Tec 45 course is the second part of the full PADI Tec deep diver program. You will extend your depth limit to 45 meters/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 will 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.

Requirements for Tec 45

  • You must be, minimum age of 18 years.
  • Certified as a PADI  Tec 40 diver or equivalent.
  • PADI Rescue diver.

  • It’s mandatory that you demonstrate good buoyancy and trim.
