  Close your eyes with us for a moment and imagine yourself at your favourite dive location. You dive into warm crystal clear water and in an instant you are in a different world. Stress, noise and the hustle and bustle of everyday life suddenly seem far away. You become one with the silent world and are acutely aware of your senses. You notice strangely how quiet it is, far quieter than it is normally. The shyest inhabitants of the sea are hardly bothered by your presence. You enjoy the fascinating feeling of being an accepted guest, a part of your environment not an intrusion. You realise also that the air you are breathing seems strangely warm and moist. You look at your computer and suddenly notice how long you have been under water and yet your pressure gauge indicates that you have plenty of gas left and no decompression in sight so you continue to swim effortlessly around. For the first time you truly experience the silence of inner space. No it isn't necessary to wake up now, this is not a dream, we have just help you imagine what tens of thousands of divers all around the world have already experienced. You have just imagined what diving with a rebreather is like - a Dräger rebreather.

Dräger semi-closed rebreathers allow you to experience diving like never before. What is unique about rebreather systems is that your exhaled gas is not released into the water as in conventional open circuit systems, but is purified and returned to the breathing circuit. The Dräger rebreathers remove carbon dioxide from the exhaled gas through the sodalime canister and then returns it to the inhalation bag, where it is enriched with fresh Nitrox from the supply cylinder. This constant supply of fresh gas ensures that you are provided with enough oxygen. If however you should need more gas a bypass valve opens automatically to supply additional fresh gas. If your breathing rate slows the circuit opens and little air bubbles escape almost silently through the exhaust valve behind you. Since there is optimal reuse of the exhaled gas, your gas consumption drops by up to 90%. Thus the mixed gas cylinder could last for a whole weekend of diving.
