Tec 45 Program                                TecRec Logo

Tec 45 Course

The Tec 45 program is designed to take students who have completed the Tec 40 program or equivalent, and extend their training to include deeper waters and longer decompression times.  The Tec 45 program is the second of three parts of the Tec Deep Diver certification.  It is the first of the three programs that introduces divers to diving below recreational limits.  For those divers that dove a nonstandard technical rig during the Tec 40 course the Tec 45 course requires the use of the standard technical rig (backplate, harness and wings) and doubles (twin tanks). In addition, the Tec 45 program introduces divers to the use of up to 100% oxygen as a decompression gas for the purpose of accelerating decompression. The Tec 45 program is an integral part of preparing divers for the final stage of their non tri-mix technical training that is the Tec 50 program.


What You Learn

  • The skills and equipment and planning need to dive to a maximum of 45 meters/145 feet
  • The knowledge to plan and execute single and repetitive decompression dives using a single stage cylinder of EANx or oxygen to accelerate or add conservatism to the decompression stops.
  • There would be no time limit to amount of decompression
  • Prepare for and respond to foreseeable technical diving emergencies 
  • Master the basic skills and procedures you’ll need as you move into deeper technical diving

The Learning Materials You'll Need

  • tec diving lingo
  • emergency procedures
  • standard technical diving equipment
  • decompression and stage cylinder handling
  • gas planning

The pak includes a manual, dive planning checklist and dive planning slate. The optional Equipment Set-up and Key Skills video on DVD is a great tool to help you practice at home in between your tec diving adventures. You'll continue to use the Tec Deep Diver Crew-Pak through Tec 50.
