A Rebreather is a diving time machine and is great for: Get close to marine life – Rebreathers don't create bubbles or noise making you a natural part of the underwater environment. Exploring Underwater – Rebreathers use gas efficiently, allowing you to stay underwater for several hours so you can take your time and enjoy the little (and big) things! Underwater photography and videography - Marine life will come close for this great shot without distracting bubbles in the frame or buoyancy changes affecting your aim. Relaxed diving – Respirators circulate hot, moist gas at ambient pressure, so it's just like breathing above the surface! How a Rebreather works: A rebreather system allows the diver to "rebreathe" their gas by circulating the breathing gas around the diver, rather than expelling the gas directly into the water as in a scuba system. This makes rebreathers extremely efficient, quiet and bubble-free! Key Advantages of closed circuit diving: While a rebreather may not be the best choice for every dive and every diver, it is the best choice for many divers and for many dives. Rebreathers have the following key advantages over conventional scuba/open circuit: A closed loop system is less noisy than an open loop system and makes interaction with marine life more intense and closer as wildlife will approach you rather than move away from you. In a rebreather system, the duration of a dive is usually much longer, meaning you can stay on a dive longer or do several repetitive dives without needing to refill your cylinders. This is because you are not using your gas as fast as in a normal tube system, because you are constantly reusing the gas, which makes the rebreather 96% efficient compared to 4% efficiency during open circuit. plunge. Especially when you engage in technical diving, your gas costs will decrease. No decompression time is much longer in a rebreather system as this ensures you have an optimal gas mixture at any depth, thus minimizing nitrogen uptake. If you're a certified Nitrox diver, you can compare it to a nitrox mixer on your back that ensures you have the best mix at any depth. The open circuit system gives you cold and dry gas, but in a rebreather you get moist and hot gas, which is much more comfortable to breathe while diving. There is no need to take deep breaths as the loop is an extension of your lungs. You just need to make sure that you are constantly breathing normally. Your buoyancy will not change with the way you breathe; it will only change when you add gas to your flotation device.
