Rebreather Purchase question

[Inspirationdiver]

CCR's are much more efficient with gas consumption, so you can make much longer dives on less gas. They also can easily be used with trimix. Some people have modified their SCR's to use trimix with them but they don't work quite as well. Another advantage of CCR's over SCR's is constant PO2. This gives you the optimum breathing gas at every depth, which can significantly shorten your decompression time.
