Recently purchased some used gear and was going to take it into my local dive shop for general maintenance.. Was BLOWN away by how much they charge for service! To take a look at my octo kit and bcd was going to cost an estimated $200 for labor and parts kits.. This really seems like a rip off to me. Am I just being unrealistic? Is there a checklist of what you can do yourself to ensure that your gear is safe for diving? Thanks in advance for your comments and advice. Philip Nelson San Antonio, TX 10 year novice diver..
