What will you learn?
Rebreather Diving Courses: Our Rebreather courses are a taught utilizing the simplest, best and most reliable CCR rebreather concepts on the market, including the Fathom CCR.
Training on a CCR is a welcome challenge but a different experience than an open circuit experience. There’s a new learning curve followed by a lot of fun and bottom time that allows you to gain hours and experience on your choice of rebreather configuration.
Train in a traditional “light” CCR setup with 3L cylinders, Tech CCR configuration with either dual AL40’s (wetsuit) or Steel LP 50’s (drysuit) as well as a multitude of other Rebreather Configurations from CCR to PSCR and Sidemount for those looking to try a series of styles of CCR’s.
Whether you’re located in Ontario, Canada, or abroad, we teach these classes whenever and wherever possible. Students fly in, drive in or fly us out to them, we’re flexible and here for you.
When diving with a CCR there’s the benefit of breathing warmer, more moist breathing gas on colder water dives. Less bubbles for more up close and personal big creature interactions, but have more to monitor in comparison to open circuit scuba and the units dive differently so mastering buoyancy can be a bit of a challenge again.
Learn the features and functions of the rebreather, how the units are put together and dismantled for cleaning, maintenance and service.
You’ll be reviewing the nitrox concept and getting more involved with bailout scenarios, system checks, gas physiology, advanced gas management, inspired gas PO2 and much more.
We will be getting into rebreather technology looking a all Types of RB’s from SCR, pSCR, CCR, ApSCR.
We will discuss:
- Efficiency vs Injection
- O2 drop
- Problem Solving :
- Flooding
- Lost gas
- Volume loss
- Failures
- Accident Analysis. Current up to date
- Mixed Gas RB Diving.
- Nitrox and Trimix
- Single gas injection
- Multiple gas injection management
- RB Decompression Procedures
- Advanced gas management & Planning
- Stage use,
- RB Sidemount
- Bailout Rebreathers
- Decompression techniques
- Decompression rebreathers
- Course Examination
Prerequisites:
Basic Nitrox is the starting point for any rebreather training, however, we do not feel that is enough. We suggest all rebreather candidates have completed Intro to Tech and we recommend hold at least a Tech 1, Cave 2 or Trimix 1 certification and are proficient with all of skills, especially bottle handling before moving on.
Rebreathers require more awareness, you have to multi-task, be aware of your surroundings, your breathing, your depth as your buoyancy is different on RB than on OC, so the more experience you have as a diver, the more it should help mentally prepare you for rebreather diving.
Our rebreather courses focus on modern technology, the right configuration (matching you up with double AL40’s or Faber 50’s with a dual isolation manifold and a long hose/short hose/spg sort of configuration reminiscent of doubles, or you can do it dil and o2 if you want to dive old school).
You can also do the class in 3L Cylinders, but it does make for a slightly more complicated configuration. 
One of the biggest advantages to training with us is you don’t need to buy your own rebreather!
Look at all the divers who buy one, hate it, are forced to use it out of pride and obligation and it ends up not being the best choice for them.
At DDS our Rebreather training allows you to rent your unit and see how much easier our preferred rebreather is to dive, trim out, breathe from and expand it out for more advanced diving endeavours. Ultimately the choice is yours, but we recommend doing it right the first time and training on a Fathom CCR or White Arrow Explorer Rebreather.
Additional Details:
If there’s a rebreather we don’t personally teach we can refer you to someone who does.
This course is aimed for experienced technical and/or cave divers who are searching to utilize rebreather technology
in all types of diving environments.
Proper information including the most current procedures and techniques are applied to safe preparation, operational management and the efficient maintenance of rebreathers in all of it’s efficiency modes.(SCR, pSCr, ApSCR and mCCR).
Unit familiarity, skill mastering and actual experience build up are the basis in this program.
