This is an on going question. Most Dive Shops take the if we don’t or haven’t sold it to you we won’t service the equipment with exceptions i.e. I am a certified diver and have move from one city to another and am looking to get set up with a local dive shop. The other question is the one of buying locally versus internet perchases. Local Dive Shops rely on divers buying from them as opposed to buying else where. I have personally seen divers buy off the internet and then find out the equipment is either no good or can’t be serviced locally and then they have to ship, at their cost, to have it repaired, and then pay to have it shipped back to them. All of the arguements aside, my question is, with all the training that we go through to become a certified diver, along with all the specialties and the more advanced certifications why would I buy life support equipment sight unseen, used and completely unfamiliar with its operation? Like I said this is LIFE SUPPORT EQUIPMENT, why take a chance on the unknown. In my opinion SUPPORT YOU LOCAL DIVE SHOP AND LIVE!!
