PADI Tec 40 CCR
The future of deep tec diving belongs to the CCR (closed circuit rebreather) and the Tec 40 CCR course is where it all starts. If you’re interested in technical diving and want to dive a rebreather, the Tec 40 CCR course is your entry into the tec diving realm.
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.
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.
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.
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.
What will I do?
You’ll learn to make no stop or limited decompression dives using a Type T CCR to a maximum depth of 40 metres/130 feet during eight training dives. You’ll also cover:
• Basic CCR function
• Tec equipment and CCR setup and checklists
• Diving CCRs and handling potential problems
• Decompression software and open-circuit bailout requirements
• Post-dive procedures and disassembly
• Thinking like a Tec CCR diver
What scuba gear will I use?
You’ll use standard tec diving equipment appropriate for the local environment, including your exposure suit, mask, fins and weight system. Snorkels are optional, but a collapsible snorkel can be carried in your pocket. You’ll also need a Delayed Surface Marker Buoy (DSMB) and reel, an audible surface signaling device, slate and a compass. Your PADI Tec 40 CCR Instructor will advise you about the Type T CCR you’ll learn to use and suggest a CCR dive computer with open-circuit bailout capability (if not integrated into the CCR), offboard life support system, and oxygen analyzer along with other beneficial gear.
After certification as a PADI Tec 40 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.
Your instructor will make sure that all Type T CCRs used in PADI courses meet requirements, such as being third party tested and that manufacturers ensure their CCRs meet a comprehensive list of requirements.
What are the prerequisites for this course?
To take a Tec 40 CCR Diver course, you must:
• Be a PADI Advanced Open Water Diver
• Be a PADI Enriched Air Diver
• Be a PADI Deep Diver or show proof of 10 dives to 30 metres/100 feet
• Have a minimum of 30 logged dives, with at least 10 dives using EANx deeper than 18 metres/60 feet
• Be at least 18 years old
• Before Training Dive 5, be certified as a PADI Rescue Diver
• Before certification, have at least 50 logged dives.
Note that qualifying certifications from other diver training organizations may apply – ask your Tec 40 CCR Instructor.
