Rebreather Explorer Course CCR & PSCR

What will you learn?

Training with rebreathers is a different experience all together.  There’s a learning curve followed by a lot of fun and bottom time and the Rebreather Explorer Course allows you to experience a multitude of Rebreather Configurations from CCR to PSCR and Sidemount!

Rebreather training available in semi and fully closed rebreathers

Divers have the benefits of warmer, more moist breathing air for cold water diving, 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:

  1. Efficiency vs Injection
  2. O2 drop
  3. Problem Solving :
    1. Flooding
    2. Lost gas
    3. Volume loss
    4. Failures
  4. Accident Analysis. Current up to date
  5. Mixed Gas RB Diving.
    1. Nitrox and Trimix
    2. Single gas injection
    3. Multiple gas injection management
    4. RB Decompression Procedures
  6. Advanced gas management & Planning
    1. Stage use,
    2. RB Sidemount
    3. Bailout Rebreathers
  7. Decompression techniques
    1. Decompression rebreathers
  8. Course Examination

Prerequisites:

Discover Rebreathers DDS or as part of a Discover RB, RB1 or RB2 class

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 you have completed at least a Tech 1, Cave 2 or Trimix 1 course and are proficient with all of your skills, especially bottle handling at this level 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 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, breath from and expand it out for more advanced diving endeavours. Ultimately the choice is yours, but we recommend doing it right the first time.

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).

Intense skill mastering and actual experience build up are the basis in this program.
