Tec 40 CCR

The first level of training with Type T CCRs

The Tec 40 CCR Diver Course with Hollis Prism 2

Learn to plan and make dives using air diluent and air or enriched air (EANx) bailout gas on Type T (technical) closed-circuit rebreathers (CCR) to a maximum of 40 metres with a single decompression stop of no more than 10 minutes.

The Hollis Prism 2 is a fully closed circuit Rebreather, ideal for exploring open ocean, cave, or wrecks. This 5 day course trains you to dive to 40m with up to 10 minutes deco using the Prism 2 CCR.

This training is significantly more challenging than recreational rebreather diving because divers learn to be both a tec diver as well as learning to tec dive with a CCR.


  • PADI Advanced Open Water Diver, PADI Enriched Air Diver, PADI Deep Diver (or have experience of more than 10 dives to 30m) certification and at least 30 dives logged with specific experience requirements.
  • Prior to Training Dive Five, student divers must be certified as PADI Rescue Divers
  • Prior to certification, student divers must have 50 dives logged.
  • There are provisions for other qualifying certifications.
  • 18 years old

What is a closed-circuit rebreather?

Closed-circuit rebreathers are a type of scuba that reuses the gas you exhale. This is the primary difference between CCR and open-circuit scuba.


Tec 40 CCR Qualifier program

Due to differences between CCRs, divers qualify on as a Hollis Prism 2 CCR diver, however, once qualified you will not need to repeat the entire course if you want to learn to dive a different Type T CCR. The Tec 40 CCR Qualifier focuses on the knowledge and skills divers need to cross over from one Type T CCR to another.

Background on Closed Circuit Rebreathers

Technical diving has been revolutionized by the development, availability and reliability of Closed Circuit Rebreathers. CCRs provide numerous benefits to the technical diver, including: reduced gas consumption, optimum EANx blends for decompression and a wider range of solutions to equipment problems. Consequently, CCRs potentially allow the technical diver greater access to time underwater - greater time based on gas logistics when compared with an open circuit technical diver and more time available to find solutions to gas management problems. As time is a critical and finite resource divers wanting to dive at and beyond the recreational envelope can now choose PADI Technical CCR training to achieve their goals.
