The dive shop may be shipping the reg. set out for repair. Most do. I don’t think dive shops are that busy with the economy the way it is. So why else does it take that long to service gear? In most cases the owner seems to try to repair when he’s bored enough.. A decent technition needs to do at least 100 units a year minimum. I never understood the poor maketing skills of the LDS. Dive shops are run more like a hobby venture then a business. I don’t want to be the dive shops buddy. Just get my gear finished when its schedualed to be. It takes 3 hrs for me to annual service a complete 1st,2nd and octo. regulator set. Over 300 sets in the past 9 months.
