TEC 100 CCR The top of the PADI Tec CCR diver training

The Tec 100 CCR Diver

Tec 100 CCR Diver is at the top of the PADI Tec CCR diver training. In this course, you’ll learn to plan and make hypoxic trimix/ heliox dives using a Type T (technical) CCR to a maximum of depth of 100 meters/ 328 feet, carry and manage multiple bailout cylinders and complete multiple decompression stops.

The Tec 100 CCR Diver course addresses technical diving with Type T CCRs, which include a range of electronic CCRs (eCCRs) and manual CCRs (mCCRs). Tec 100 CCR Diver refines your ability to diagnose, understand and effectively respond to life-support problems.

This training is significantly more challenging than the Tec 60 CCR Diver Course in part because it includes the use of diluents and bailout gases you cannot safely breathe at the surface. Successful Tec 100 CCR Diver course completion requires divers to demonstrate the superior level of skill necessary to competently dive a technical CCR at exploration depths.

What you'll learn

Going deeper than 60 meters/ 200 feet brings up a few key considerations that you'll focus on during this course, beyond what you already know as a Tec 60 CCR Diver.

During knowledge development, one confined water dive and five open water dives, you'll cover:

  • Diving with hypoxic trimix/ heliox diluent to complete a technical dive, with its necessary decompression obligations deeper than 60 meters/ 200 feet
  • Carrying a wide range of high/ low oxygen and trimix/ heliox bailout cylinders and choosing bailout gases
  • Dealing with CCR problems and dive emergencies at extreme depths

After qualifying as a PADI Tec 100 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.

Tec 100 CCR Refresher

This Refresher Program covers the level of skills required to make Tec 100 CCR dives. Divers may also refresh skills appropriate for the Tec 40 and 60 CCR Diver courses 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)
  • At least two more bailout cylinders
  • Drift kit (if drift decompressing


  • Tec 60 CCR Diver course certification (or qualifying certification from another organization).
  • Proof of 175 logged dives, with at least 50 dives and 100 hours experience diving the Type T CCR used in the course with off board bailout systems. At least 25 of these dives must be multistop decompression dives deeper than 40 meters/ 130 feet with trimix/ heliox diluent.
  • 18 years of age.
