You only need to make sure that you continually breath normal breaths. There is no need for deep breaths because the loop is an extension of your lungs. If you are a certified Nitrox diver, you can compare it to having a nitrox blender on your back that makes sure that you have the best mix at every depth.Īn open circuit system gives you cold and dry gas, but on a rebreather you will get moist and warm gas, which is much more comfortable to breathe while diving. No decompression time is far greater on the rebreather system as it makes sure you have the optimal gas mix at every depth, therefore minimizing the intake of nitrogen. Your gas costs will be reduced, especially when you venture into technical diving. The reason for this is that you will not use up your gas as fast as on a normal scuba system, because you are re-using gas the whole time, making the rebreather 96% efficient in comparison to 4% efficiency during an open-circuit dive. The duration of a dive on a rebreather system is generally much longer which means that you can either stay down longer in one dive or do several repetitive dives without the need to re-fill your cylinders. Rebreathers have the following key advantages over traditional scuba / open circuit.Ī rebreather system is less noisy than an open circuit system, making the interaction with marine life more intense and up close, as wildlife will approach you rather than swim away from you. While a rebreather isn’t the best choice for every dive and every diver, it is the best choice for many divers and many dives. Alarms are delivered visually, by the wrist computer and the smart battery, audibly via the battery and physically, via the mouthpiece that incorporates Juergensen Marine's DIVA vibrating alert technology. A three-level alarm system is there to alert the diver and buddy if something does not go according to plan. Gas levels within the loop and the cylinders are monitored to ensure that the SE7EN+ diver has sufficient diluent gas available to reach the surface in the unlikely event of needing to “bail out” to open circuit. Throughout the dive, Poseidon safety technology is monitoring the oxygen sensors to ensure that they are working perfectly. So simple, in fact, that the SE7EN+ diver can just enjoy the dive! The Poseidon SE7EN+ is an example of technology at its best taking a complex process and making it beautifully simple. The SE7EN+ diver does not need to adjust PPO2 set points or manually maintain a set point the SE7EN+ does it all for them. The oxygen sensors detect the PPO2 in the breathing loop and solenoids automatically inject oxygen as required to maintain the appropriate PPO2 for the diver’s current depth. What makes the Poseidon SE7EN+ unique is the way in which it manages the gas in the breathing loop. That’s the easy part and where other rebreathers stop but Poseidon SE7EN+ technology really starts! All closed circuit rebreathers use oxygen, diluent (air/trimix), a breathing loop, counter-lungs, a mouthpiece to deliver the breathing gas, a scrubber to remove the carbon dioxide from the system and a method to replace the metabolized oxygen.
