Your SCUBA equipment is your lifeline underwater. As a diver you need to treat your regulator and BCD like life support equipment. You need to know everything is functioning well and delivers air the way it was designed. Too many divers have the "She'll be right" attitude. Reality is that once you notice any issues, it is too late. Just giving it a tap won't fix the problem.
Be aware that every regulator brand and model are different so we are happy to quote on any work, but we will need to see your equipment as it is impossible to quote accuratly over the phone.
So bring your Regulator and BCD in for its annual service today.
Andy has been servicing Dive Equipment for many years and will make sure your equipment keeps preforming to the level it was designed to. Feel free to ask him or any of the friendly staff at Dive HQ about your servicing and diving needs.
