There are several types of rebreathers: closed circuit, open circuit, and "mixture" rebreathers. Each type has its advantages and disadvantages. This article will describe the most common types of rebreathers, and what to look at when choosing one. The last section will detail which rebreathers can't disrupt 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
You might choose to compare semi-closed circuit and closed-circuit rebreathers systems when you have the option. Although these two types are similar in principle, the main differences in how gas is delivered and mixed are significant. The type of rebreather that you choose depends on your goals and requirements.
Continuous-flow "mixture rebreathers"
Most continuous-flow breathathers are designed for long dives. But the newest versions of these rebreathers allow you to breath with the same oxygen content as your natural air. This allows you to breathe easier and protects against bacteria contamination. Rebreathers also have a higher durability and reliability than ever before. The rebreathers can also be used in water-free environments, as long they are correctly used.
Purging oxygen rebreathers
Rebreather divers must have a source for oxygen to ensure constant flow of gas. The diver's rebreather has a cylinder to store the source of gas. Pure oxygen, also known as liquid oxygen, makes breathing easier. Rebreather divers must inhale a mixture of both gasses. There are two types: active and passive addition rebreathers. Both types of rebreathers are similar. These rebreathers differ in the volume of gas. The best way to prevent hypoxia is for divers to be familiar with both.
Rebreathers don't disturb marine life
Rebreathers don't cause any harm to marine life. Rebreathers offer underwater diving a quieter experience than open-circuit divers, which are noisy with gushy and clogged gas. 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 are expensive
Rebreathers are essential medical equipment for those in the military, law enforcement, and other high-risk situations. Increasing awareness about the safety benefits and cost savings of rebreathers has driven the development of the industry. The high cost of these devices might discourage many from using them. Listed below are a few tips to reduce the cost of rebreathers. Continue reading to find out more.
Safety concerns for divers using rebreathers
Safety concerns regarding rebreathers exist, although they are very rare. Some studies show that rebreather diving can be up to 10 times riskier than open-circuit scuba. Rebreather divers are actually safer than base jumping or skydiving in terms of deaths. Rebreathers must be diligent and determined in applying safety protocols to minimize risks.
