far too often for my taste, see http://www.scubaboard.com/showthread.php?t=152757laserdoc:Yes but how often do you have a reg break on you when you are traveling. I also have a older oasis thats about 15 years old. I toss this one in the dive bag just in case something does happen. Never had to use it. Always get my regs serviced once a year before the big dive trip even if they don't need it anyway.
