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

The Tec 60 CCR Diver

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 meters/ 200 feet and complete multiple decompression stops while carrying adequate bailout 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.

What you'll learn

You will complete one confined water dive and six open water dives. Building on the technical diving knowledge and skills you acquired in the Tec 40 CCR course.

You will cover new topics such as:

  • Different bailout strategies
  • Offboard gas supply capability
  • Planning Tec CCR decompression dives including deep deco stops
  • Offsetting narcosis with helium gas mixes
  • Dealing with CCR problems and dive emergencies

After qualifying as a PADI Tec 60 CCR Diver, you'll need to qualify if you want to use a different Type T CCR model because procedures vary with each model. However, you don't need to repeat the entire course. Just take a PADI Tec CCR Qualifier program that focuses on the knowledge and skills needed to use a different Type T CCR model.

The Tec 60 CCR Refresher

This Refresher Program covers the level of skills required to make Tec 60 CCR dives. Divers may also refresh skills appropriate for the Tec 40 Diver course as well, if required.

Scuba gear you'll use

  • Stage/decompression cylinders with regulator, SPG, mounting hardware and proper labeling/markings. Two per diver will be required
  • Backup decompression cylinders as appropriate and required for the environment
  • BCD and harness – redundant buoyancy control is required (double bladder BCD or dry suit if suitable for weight of equipment worn)
  • Depth gauge/computer and backup depth gauge/computer
  • Timing device and backup timing device
  • Trimix decompression information (tables/trimix computer) and backup decompression information
  • Exposure suit appropriate for environment and dive duration. (If you use a dry suit, you should be trained/experienced with its use in recreational and technical diving prior to using it for trimix training or diving.)
  • Argon dry suit inflation or other inflation system as needed
  • Weight system (if needed)
  • Jon line (if needed for current diving environments)
  • Delayed Surface Marker Buoy (DSMB)
  • Reel
  • Lift bag (bright yellow or per local community practice preferred)
  • Dive knife / cutting device and backup slate, backup mask (optional)
  • Compass, lights (optional)
  • Drift kit (if drift decompressing)


  • 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 meters/ 100 feet.
