Closed Circuit Rebreathers have become much more main-stream in recent years. They allow longer dive times, optimisation of decompression and a huge reduction in noise and bubbles. They also allow for access to deeper technical diving without the weight and expense involved in large Open Circuit Trimix fills.

The Tec 40 CCR course is the entry level into Tec diving on a Rebreather. This first level of training introduces you to Type T CCRs, which can be electronic CCRs (eCCRs) and manual CCRs (mCCRs). During the course, you focus on developing the discipline it takes to be a technical diver while learning the details of proper setup, predive checks, dive planning, failure and problem management and teamwork for CCR diving.

The disadvantages are discipline, training and cost.


You’ll learn to make no stop or limited decompression dives using a Type T CCR to a maximum depth of 40 metres/130 feet during eight training dives. You’ll also cover :

  • Basic CCR function
  • Tec equipment and CCR setup and checklists
  • Diving CCRs and handling potential problems
  • Decompression software and open-circuit bailout requirements
  • Post-dive procedures and disassembly
  • Thinking like a Tec CCR diver


This course will be running over the following weekends in 2018 :

April 7/8, 14/15, 21/22
August/September 25/26, 22/23, 29/30

The price including all knowledge development, course materials, rebreather hire and materials, and eight training dives is €1,190.

There is an option of adding two more guided dives to consolidate experience on the final making the total €1,400.
