There are three types of rebreathers available: open circuit, closed circuit and mixed circuit. All have their pros and cons. This article will describe the most common types of rebreathers, and what to look at when choosing one. The last section will show you which rebreathers do not disturb marine life. It doesn't matter what rebreather you choose; make sure it works in the environment you are going to be.
Semi-closed circuit Rebreathers
One might feel tempted to select a closed-circuit model if you are comparing semi-closed or closed circuit rebreathers. Although these two types are similar in principle, the main differences in how gas is delivered and mixed are significant. Your specific needs and goals will determine which type of rebreather you choose.
Continuous-flow "mixture rebreathers"
Continuous-flow rebreathers tend to be used for extended dives. The newest models allow you to inhale with the same level of oxygen as your surrounding air. This enables the user to breathe more easily, while still being protected from bacterial contamination. The rebreathers are also more durable and reliable than ever before. You won't have any problems breathing in water as long as you use them correctly.
Purging oxygen rebreathers
To provide constant gas flow, a rebreather diver must have access to oxygen. The rebreather attaches to a cylinder which holds the gas source. Pure oxygen, or liquid oxygen, increases the work of breathing. Rebreather divers need to breathe in both liquid oxygen and pure oxygen. There are two types: active and passive addition rebreathers. Both types have similar functions. The only thing that makes these rebreathers different is the volume. A diver should be aware of both methods, as this is the most effective method of preventing hypoxia.
Rebreathers don't disturb marine life
Rebreathers don't cause any harm to marine life. Rebreathers provide an underwater dive experience that is more pleasant than open-circuit, which has noisy valves and gushy air. Rebreathers are also much more comfortable than other diving equipment, so the only concern you should have is how comfortable you'll be breathing.
Rebreathers: Cost
Rebreathers are vital medical equipment for personnel in law enforcement and military. Rebreathers have been growing in popularity due to their safety and cost savings. But, many people might not use them due to the high price. Here are some tips that can help reduce the cost associated with rebreathers. Continue reading to learn more.
Safety concerns for divers who use rebreathers
Rebreather safety problems are rare but do exist. Some studies show that rebreather diving can be up to 10 times riskier than open-circuit scuba. Rebreather diving actually causes fewer deaths than base jumping or skydiving. To reduce risk, rebreathers must be determined and consistent in following safety protocols.
