Who needs bubbles? Dive Silent. Dive Longer. Dive Rebreather.
What is a rebreather?
In a nutshell, it is the future. Closed Circuit Rebreathers (CCR) are cutting-edge scuba diving technology, and require specialized training and equipment. Rebreather systems filter out the CO2, or “scrub” the air you breathe, recycling the gas in a closed-loop so there are no bubbles. That's right, NO BUBBLES. With rebreather diving you dive in a silent world, getting closer to marine-life than you ever thought possible. They will barely know you are there! This allows you to get some truly amazing photos and videos. CCR also enables divers to stay down longer - it is about as close as you are going to get to living with the fishes. Serious expedition divers, cave divers, videographers and photographers are just some of the people who use closed-circuit rebreathers – and now you can too.
The Hollis Prism2:
The Prism2 is a fully closed circuit Rebreather, ideal for exploring open ocean, caves, or wrecks. This unit can be electronically or manually controlled which means you choose how you want the loop PPo2 maintained. It includes shoulder mounted counter lungs and rear mounted radial scrubber which provides easy breathing with low resistive effort and low hydrostatic loading. The standard kit includes an electronic secondary control and primary LED displays with a back-plate/wing assembly that provides a complete kit ready to dive out of the box. Unit can also be purchased with or without tanks/valves.
- Electronic CCR (Closed Circuit Rebreather)
- Sealed electronics
- Radial scrubber design provides lower resistive breathing effort and more efficient scrubber use
- Primary HDD (Heads-Down Display) is a battery driven sequential LED for continuous hands-free monitoring
- Over the shoulder counter-lungs for decreased work of breathing
- O2 supply lines and solenoid are external from the breathing loop - removing the risk of O2 spikes due to O2 connection leaks. O2 is safely vented into the surrounding water column.
- Pre-dive user selectable PO2 set-points
- Standard Diluent and O2 bottle size: 19 cuft (2.7 liters). Accommodates 13 cuft (1.9 liters), 19 cuft (2.7 liters), and 30 cuft (4.4 liters).
- Electronics and the battery are housed on their own outside of the breathing loop
- 40 hour battery life (in 70F water temp) with standard 9V alkaline battery
- Purge drains at the base of each counter-lung
- Waterproof magnetic slide on/off switch used for reliability
- 3 redundant O2 sensors for reliable O2 management
- Sealed electronics
The science of it
Technically speaking, as open circuit (SCUBA) divers we rely upon filling our lungs with air from a pressurized gas tank with every inhalation and then exhausting that volume of air into the surrounding water with every exhalation. As we descend deeper the water pressure around us increases and the volume required to fill our lungs increases. In other words, our air supply depletes quicker the deeper we dive. A rebreather recycles rather than vents the exhaled breath. The exhaled breath passes into a closed loop, where it is pushed through a chemical absorbent (scrubber) to remove the carbon dioxide, and returns through the other side of the loop for the diver to "re-breathe", hence the name "closed circuit rebreather" or CCR. The future is here.

Paperwork and Administration
Medical Statement - The student must have a physician's approval and signature on the Medical statement. If the student received a physician's approval and signature on a Medical Statement for another course within the last year and has had no medical condition change, and if you have that Medical Statement on file, then the student diver does not need to see a physician again.
Tuition: $1777.50 USD includes class fee and TEC CCR 40 Crew Pak.
