There are three types of rebreathers available: open circuit, closed circuit and mixed circuit. Each type has its advantages and disadvantages. This article will explain the most common rebreathers and what to look for when choosing a rebreather. The final section will tell you which rebreathers won't harm marine life. Whatever rebreather you choose, ensure it fits the environment where you'll be.
Semi-closed circuit Rebreathers
If you're comparing semi and closed circuit rebreathers, it might be tempting to go with a closed circuit model. They are both similar in principle. However, there are some differences in the way that gas is delivered. You will need to consider your specific goals and needs before deciding whether you want a closed-circuit or semi-closed-circuit model.
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 are more reliable and durable than ever. As long as the rebreathers are used properly, they won't be able to inhale water.
Purging oxygen rebreathers
To ensure constant gas flow, a diver who rebreather uses oxygen. The diver's rebreather has a cylinder to store the source of gas. Liquid oxygen (or pure oxygen) increases the effort of breathing. Rebreather divers should inhale mixtures of both gases. There are two kinds of rebreathers: passive and active addition rebreathers. Both types of regulators are the same. The only difference is the amount of gas used. Divers should know both, as it is the best method to prevent hypoxia.
Rebreathers don't disturb marine life
Rebreathers have one major advantage: they don't interfere with marine life. Rebreathers provide underwater diving with a more enjoyable experience than open-circuit dives that have noisy valves or gushy gases. Rebreathers are more comfortable than other equipment so your only concern should be how comfortable you will breathe.
Rebreathers are expensive
Rebreathers are an indispensable medical device for people in high-risk situations such as the military and law enforcement. Rebreathers have been growing in popularity due to their safety and cost savings. The high cost of these devices might discourage many from using them. Below are some ways to reduce the cost for rebreathers. Continue reading for more information.
Safety concerns for divers using rebreathers
While safety issues surrounding rebreathers are relatively rare, they do exist. Rebreather diving is up to 10 times more risky than open-circuit scuba, according to some studies. Rebreather diving is safer than base jumping and skydiving, with fewer fatalities. Rebreathers must be dedicated to following all safety precautions in order to reduce the risk.
