Rebreather Training
At Proper Diving we are excitted to offer the following Rebreather or CCR training:
- Dive Rite O2ptima CM (The Choptima)
- Dive Rite O2ptima Classic
- Dive Rite O2ptima
- Scuba Force Backmount Unit
- Scuba Force Sidemount Unit
Course include:
- Air Diluent CCR Diver
This is the entry level certification course for divers wishing to utilize a closed-circuit rebreather (CCR) for air diving. The objective of the course is to train divers in the benefits, hazards, and proper procedures for diving a CCR and to develop basic CCR diving skills to a maximum depth of 30 Metres/100 Feet, using air or nitrox as a diluent. No decompression diving is allowed on this course.
- Air Diluent Decompression CCR Diver / Advanced EANX CCR
This is the second level certification course for divers wishing to utilize a closed-circuit rebreather (CCR) for air diving. The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills to a maximum depth of 40 Metres/130 Feet using air or nitrox as diluent for formal decompression diving.
- Helitrox Decompression CCR Diver / CCR ART Diver
This is the second entry level certification course for divers wishing to utilize a closed-circuit rebreather (CCR) for mixed gas diving using a Helitrox diluent. The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills, to a maximum of 45 Metres/150 Feet, using an air/nitrox/helium diluent for formal decompression diving. Students are permitted to utilize a diluent and bailout mix with no greater than a 35% helium content (+/- 5%) and no less than a 20% oxygen content and are permitted to use up to 100% oxygen for decompression.
- CCR Mixed Gas Diver / CCR Normoxic Trimix
This is the intermediate level certification course for divers wishing to utilize a closed-circuit rebreather (CCR) for mixed gas diving. The objective of the course is to train divers in the benefits, hazards and proper procedures for mixed gas diving on the unit specific CCR, utilizing a mixed gas diluent containing 16 percent or greater oxygen, and to develop intermediate CCR diving skills appropriate to technical diving to a maximum depth of 60 Metres/200 Feet.
- CCR Normoxic Trimix Plus Diver
The CCR Normoxic Trimix Plus Diver course is an advanced closed-circuit rebreather (CCR) training program designed for technical divers seeking to extend their depth limits using helium-based gas mixtures, while remaining within the normoxic range. This means that although divers will use trimix (a mix of oxygen, helium, and nitrogen), the oxygen content will remain high enough to avoid hypoxic risks at the surface or shallow depths. The “Plus” designation allows certified divers to conduct dives to a maximum depth of 233 feet (70 meters), compared to the standard Normoxic Trimix CCR certification which is limited to 200 feet (60 meters).
- CCR Advanced Mixed Gas Diver / Trimix CCR Diver
This is the highest-level certification course for divers wishing to utilize the unit specific closed-circuit rebreather (CCR) for advanced mixed gas diving. The objective of the course is to train divers in the benefits, hazards, and proper procedures for advanced mixed gas diving on a CCR and to develop advanced CCR diving skills appropriate to technical diving to a maximum depth of 100 Metres/330 Feet.
- Advanced Wreck CCR
The Advanced Wreck CCR (Closed-Circuit Rebreather) course is an intensive technical diving program designed to build on foundational rebreather skills by focusing on complex wreck penetration techniques, advanced dive planning, and emergency management in overhead environments. Divers learn to navigate intricate wreck structures safely, manage extended decompression schedules, and utilize specialized equipment while emphasizing gas management, team communication, and problem-solving under challenging conditions. This course prepares experienced CCR divers to explore deeper, more complex wrecks with confidence and precision, enhancing both safety and enjoyment in demanding underwater environments.
- Cave CCR Diver & Technical Cave CCR Diver
The Cave CCR Diver course is an advanced overhead environment program designed for certified CCR and cave divers who wish to explore flooded caves using closed circuit rebreathers. This course combines the complexity of cave diving with the technical demands of CCR operation, focusing on safety, redundancy, and precision in gas management, navigation, and emergency procedures.
Students will learn to apply CCR-specific protocols to extended penetrations, bailout planning, and decompression within a cave environment, while maintaining control, situational awareness, and adherence to best practices for overhead diving.
