cerich:I can argue the "qualified" statement all day! I teach techs and sometimes the lack of skill and knowledge is scary!
Chris : So true, a couple of hours @ a DEMA seminar and now a "qualified" tech?
When I first started as a SCUBA rep in Southern California there was a service center known as Professional Scuba Repair. They did only service, no resale. The LA market was big enough to support such a service. They had all the tools and all the proper equipment to rebuild and repair SCUBA gear. Al Thompson took great pride in what he did. I used to stop in anytime I was in the area and just chat and learn a bit.
Your tips on finding a good service center are timely and well taken.
