As a technology that allows divers to stay submerged for longer periods compared to traditional open-circuit scuba systems, rebreathers are an essential part of our arsenal. Incorporating rebreathers into our diving practice takes meticulous preparation and training, as they are complex systems that demand a thorough understanding of their mechanics and emergency procedures.


Scuba Rebreathers recycle the gas we breathe by scrubbing out carbon dioxide and adding oxygen as needed, which means our dives are not only longer but also quieter, allowing for a closer interaction with marine life. By merging our expertise with the most reliable products on the market, we guarantee that divers walk away with confidence in their ability to use a scuba rebreather effectively and safely. For us, at Dive Right in Scuba, diving is not just an activity, but a pursuit of excellence and safety beneath the waves.

Rebreather Components and Functionality

It's important to understand the components that allow these systems to function efficiently underwater. Rebreather diving technology is sophisticated, involving several critical parts working together to provide divers with a safe and extended underwater experience.

Scrubber Canister

The scrubber canister is at the heart of a rebreather, holding the scrubber material which removes CO2 from exhaled gas. Each breath a diver takes passes through this canister where the chemical reaction with the scrubber material eliminates carbon dioxide before the breathing gas is recirculated.

Oxygen Sensors

Oxygen sensors monitor the partial pressure of oxygen (PPO2) within the loop. These sensors are crucial for ensuring that the gas mix being breathed remains at a safe concentration. Our rebreathing systems incorporate reliable sensors to help maintain the optimal balance of oxygen.


The counterlung component serves as a reservoir for the breathing gas. It expands and contracts with the diver's inhalation and exhalation, allowing us to control our buoyancy and ensuring we have enough gas for each breath.

Dive Surface Valve (DSV)

The Dive Surface Valve (DSV) is an essential part of the breathing loop, allowing divers to switch from breathing from the rebreather to open-air when at the surface. It's crucial that the DSV operates flawlessly to ensure smooth transitions and safety throughout the dive.

Closed-Circuit Rebreathers (CCR) Operation

In Closed-Circuit Rebreathers (CCR), the principle of operation is the rebreathing of the same gas supply, with CO2 being constantly scrubbed away. Our CCR models effectively reduce gas consumption and bubble production, allowing for longer, quieter dives where marine life isn't disturbed by bubbles.

Advantages of Rebreather Diving

Rebreathers offer several key benefits to enhance our underwater adventures. Many divers choose rebreathers for the significant increase in gas efficiency and longer dive times they provide.

  • Compact and lighter in weight
  • Closer encounters with marine life
  • Reduced decompression
  • Extended dive times

How to Choose a Scuba Breather?

At Dive Right in Scuba, we understand that choosing the right rebreather is a pivotal decision for any diver. Focusing on the details of each model and the support offered by the manufacturer are key factors in finding the rebreather that fits your diving style, needs, and budget.

Choosing the best scuba rebreather involves considering several factors to ensure it meets your diving needs, skill level, and budget. Here's a guide to help you make an informed decision:

Type of Rebreather

Understand the different types of rebreathers available, such as Closed Circuit Rebreathers (CCR) and Semi-Closed Circuit Rebreathers (SCR). CCRs are more complex and offer longer dive times but are also more expensive and require extensive training. SCRs are simpler and cheaper but less efficient than CCRs.

Considering the Right Model for You

Different models are tailored for varying diving activities, from casual reef tours to deep technical dives. We look at the buoyancy control, the ease of operation, and the decompression capabilities of each unit.

Models to Consider

  • Recreational Rebreathers: Ideal for shorter dives, simple operation, and lower expense.
  • Technical Rebreathers: Equipped for deeper and longer dives, complex decompression, and requires a larger budget.
  • Diluent Cylinder Size: Match the size to your anticipated dive depth and duration.

Training and Experience

Ensure you have the appropriate training and experience for the type of rebreather you're interested in. Rebreather diving requires more knowledge and skills than open-circuit scuba diving. Consider your current certification level and look for a rebreather that matches your experience.

Dive Conditions

Consider the typical conditions you'll be diving in. Depth, water temperature, and the type of diving (recreational, technical, cave, wreck) will influence your choice. Some rebreathers are designed for extreme depths and conditions, while others are suited for recreational diving.

Ease of Use and Maintenance

Look for a rebreather with user-friendly controls and displays. Maintenance requirements vary between models, so consider how much time and effort you're willing to invest in upkeep. Some units are more user-serviceable than others.

Safety Features

Safety is paramount when choosing a rebreather. Look for models with redundant systems, such as backup oxygen supply and electronics. Check for features like automatic diluent control (ADV), oxygen sensors, and fail-safes.

Size and Portability

Consider the size and weight of the rebreather, especially if you plan to travel with it. Some models are more compact and lightweight, making them easier to transport.


Rebreathers can be a significant investment. Besides the initial purchase cost, consider ongoing expenses such as replacement sensors, scrubber material, and maintenance. Determine your budget and look for a rebreather that offers the best value for your needs.

Reviews and Recommendations

Research online forums, reviews, and ask for recommendations from experienced rebreather divers. Personal experiences can provide valuable insights into the reliability and performance of different models.

Manufacturer Support and Community

Consider the manufacturer's reputation for quality and customer service. A strong user community can offer support, advice, and shared experiences which can be invaluable for both new and experienced rebreather divers.

Try Before You Buy

If possible, attend a rebreather try-dive session or course. This will give you a hands-on experience and help you decide if a particular model is right for you.
