The Tec 100 CCR Diver with EPSO

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 metres/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. In the course, you will use hypoxic trimix/heliox diluent to complete a technical dive, with its necessary decompression obligations, while carrying a range of high/low oxygen and trimix/heliox bailout cylinders.

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.


  • 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 metres/130 feet with trimix/heliox diluent.
  • 18 years of age.

Tec 100 CCR Qualifier Program

Divers wishing to apply their certification to another Type T CCR at the Tec 100 CCR Diver level will need to complete the Tec CCR Qualifier program, which covers skills and knowledge specific to the particular unit.

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.
