Your dive regulator allows you to breathe underwater and will need to be serviced annually. Even it hasn't been used for a while that's all the more reason (to ensure no moving parts have seized-up).
They are linked to your cylinder valve via either DIN or A-Clamp.
DIN can cope better with higher pressures. You should consider having an adaptor on-hand though as some dive centres in more "far flung" locations may not have the correct valves.
We can help you choose your diving regulator as we stock all the main brands. We can also service Mares regulators in-house or we can send any other brand away to one of our registered servicing locations.
