Prism 2 DiverTec 40 CCR Diver is the first level of training that addresses technical diving with Type T CCRs, which include a range of electronic CCRs (eCCRs) and manual CCRS (mCCRs).  Pura Vida Divers trains on the Prism 2 Rebreather by Hollis.


Tec 40 CCR Diver introduces student divers to diagnosing life-support problems and, when possible, returning to the loop to complete the dive with limited decompression obligations. 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.



What is a closed-circuit rebreather?

Closed-circuit rebreathers allow divers to reuse the gas you exhale. This is the primary difference between CCR and open-circuit scuba.

All CCRs used on PADI TecRec CCR courses must be third party tested and manufacturers must ensure they meet a comprehensive list of requirements and register them with PADI.  Pura Vida Divers is proud to represent the Hollis line of Rebreathers which meet the PADI requirements.


About the Hollis Prism 2Prism 2 Rebreather

The Prism2 is a fully closed circuit Rebreather, ideal for exploring open ocean, cave, or wrecks. This unit can be electronically or manually controlled which means you choose how you want the loop PPo2 maintained. includes shoulder mounted counter lungs and rear mounted radial scrubber which provide easy breathing with low resistive effort and low hydrostatic loading. The standard kit includes an electronic secondary control and primary LED displays with a backplate/wing assembly that provides a complete kit ready to dive out of the box. Unit can also be purchased with or without tanks/valves.


Tec 40 CCR Qualifier program:

Due to differences between CCRs, divers qualify on individual CCR units.  We offer training on the Hollis Prism 2 Rebreathers.  Once qualified on either of these units, 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

The development, availability and reliability of Closed Circuit Rebreathers (CCRs) revolutionized technical diving.  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 gas management crucial, divers wanting to dive at and beyond the recreational envelope can now choose PADI Technical CCR training to achieve their goals.
