TEC 60 CCR Plan and make dives using trimix/heliox as a diluent using a Type T CCR

The Tec 60 CCR Diver with REEF DIVERS

Tec 60 CCR Diver is an intermediate technical Closed Circuit Rebreather (CCR) diver program where you'll learn to use life support equipment in completing dives outside the recreational and air diluent envelope.
You will learn to plan and make dives using trimix/heliox (minimum 16% oxygen) as a diluent using a Type T CCR to a maximum depth of 60 metres/200 feet and complete multiple decompression stops while carrying adequate bail out gas for the dive.
Tec 60 CCR Diver is the second level of training that addresses technical diving with Type T CCRs, which include a range of electronic CCRs (eCCRs) and manual CCRs (mCCRs). Tec 60 CCR develops the understanding and skills for diagnosing life-support problems while using trimix/heliox to complete a technical dive with its necessary decompression obligations.


  • Tec 40 CCR Diver or other qualifying certification
  • Proof of 150 logged dives, with at least 25 dives and 50 hours experience with the Type T CCR used in the course with an offboard bailout system following Tec 40 CCR Diver principles. At least 10 of these dives must be deeper than 30 metres/100 feet.

Tec 60 CCR Qualifier program

Due to differences between CCRs, divers qualify on each CCR. However, once qualified, if you wish to cross over to another Type T CCR, you'll only need to complete the Tec CCR Qualifier program, which covers unit-specific skills and knowledge.
