REMEMBER THIS IS YOUR LIFE SUPPORT SYTEM! Get it serviced at least twice a year or 100 dives, which ever comes first.   When you are going on a dive trip and it is near time to get them serviced, bring them in when you purchase your airline tickets, NOT the week before you leave.   Always replace your dust cover on your regulator when you remove it from your cylinder.   Always rinse your regulator in fresh water when you are done using it.   Before diving, check your mouthpieces, hoses are tight, your computer turns on and your low pressure quick release is working properly   Bragging about the last time you had your regulator serviced is not what your buddy wants to hear If you get seasick in your regulator, take care of it as soon as you get back to shore.  First thing to do is take your regulator to a garden hose place it in your mouthpiece.  Let the water run until it runs clear.
