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/130 feet with a single decompression stop of no more than 10 minutes.
Tec 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). 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 are a type of scuba that reuses 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.
Tec 40 CCR Qualifier program
Due to differences between CCRs, divers qualify on each CCRs, 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 a 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 a finite resource divers wanting to dive at and beyond the recreational envelope can now choose PADI Technical CCR training to achieve their goals.
