Don`t forget to have your regulators, BC, and instuments serviced by a CERTIFIED repair technician. How do you know the individuals are certified by the manufacturer? Look for the certifications. They are normally placed in an obvious location in the LDS. Having repaired dive gear for many years (and aircraft for 29 years), I have seen much due to neglect. Do not look for the cheapest repair costs, because YOU WILL GET WHAT YOU PAY FOR !!!! Is your life support equipment that insignificant to you? "Take care of your gear, and it will take care of you"
