We used the O2ptima, Dive Rite’s new CCR. My instructor was Mark Derrick, based out of Ft. Lauderdale, Florida. My open circuit (OC) diving background included: Dive ... http://divinggearguide.com/o2ptima-rebreather-logbook/ You can visit the photo gallery for DPVs and Scooters at DivingInDepth.com Click here. http://divinggearguide.com/photo-gallery-dpv-scooters/ Choosing a rebreather can be a difficult process. Before investing in a rebreather, there are many things to consider. A more sophisticated rebreather doesn’t mean it’s a better rebreather. Just like you purchased your open circuit gear, you must determine how you plan on using the rebreather. The difference between ... http://divinggearguide.com/choosing-a-rebreather/ You can see a photo gallery at divingindepth.com click here http://divinggearguide.com/rebreather-photo-gallery/ Mixed-gas closed-circuit rebreathers (CCR) improve upon SCR designs. CCRs are the most advanced rebreather systems and require the most upkeep and maintenance. They are also the most expensive and complex to operate and require the most extensive training. CCRs offer the best gas economy, reduced decompression obligations, and provide extended ... http://divinggearguide.com/mixed-gas-closed-circuit-rebreathers/ 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 ... http://divinggearguide.com/semi-closed-circuit-rebreath/ 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 ... http://divinggearguide.com/oxygen-rebreathers/ 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. ... http://divinggearguide.com/types-of-rebreathers-intro/ 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, ... http://divinggearguide.com/rebreather-training/
