Semi-closed circuit rebreathers (SCR) allow for the use of an inert gas to dilute the oxygen, which allows you to dive deeper. The base gas that is typically used is an EANx (nitrox) gas mix. An SCR is very similar to oxygen closed-circuit rebreathers except for the fact that they must have functionality to accommodate [...]
Oxygen closed-circuit rebreathers are oxygen-only breathing rebreathers and are the most simple design and most inexpensive type of rebreather. Because there is no helium or nitrogen to breathe, there are never any decompression requirements. Oxygen closed-circuit rebreather systems use a valve to add the oxygen into the breathing loop. The valve is designed to keep [...]
Rebreathers are diving systems that recycle your breathing gas. This drastically extends the supply of breathing gas by reusing exhaled gas. There are two types of rebreathers on the market today: closed-circuit rebreathers and semi-closed circuit rebreathers. All rebreathers are similar in design and have several of the same components. Every rebreather must incorporate a [...]
Rebreathers are diving systems that recycle your breathing gas. There are two types of rebreathers on the market today: closed-circuit rebreathers (CCR) and semi-closed circuit rebreathers (SCR) and each require specific training. There are a number of training agencies that can instruct you on diving rebreathers, such as IANTD, GUE, TDI, NAUI, and PADI. All [...]
What is a rebreather? Rebreathers are diving systems that recycle your breathing gas. It is a machine that recycles your exhaled gas so that it can be used again. What are the advantages of diving a rebreather? Gas efficiency, reduction in decompression, bubble silence (noise reduction), and no dry air to breathe. By recycling your [...]
