Rebreather diving

[Inspirationdiver]

There are many factors to consider when deciding which rebreather might be right for you. They all differ considerably in things ranging from cost, ease of use, maintainance, durability, warranty coverage, etc.. I would say to start out by doing your research and trying to decide whether a SCR or CCR unit would fit you best.
My first reaction would be to go SCR based on the depth you plan to be diving. There are definate advantages to a CCR but in my opinion the increased cost and maintainance isn't justified unless you are planning on doing some deeper dives.
