I got involved in the recreational dive industry in 1995, at the time virtually every "Sales rep" from the gear companies were teaching the repair class to shops, by the time I became a rep in 2002 it was becoming rare, by 2005 many of the brands had clinics being taught only by the repair folks or in some cases by dealers to other dealers. In the last 8 years or so, more and more shops don't service gear, they send them to one of the many reg repair business's that have popped up all over the country. It's been shocking to me how many dealers don't know how to tune a reg for delivery let alone service it. Of course along with the dumbing down process comes less faith from the consumer and yet we sit around in the dive industry wondering why diving as a industry is collapsing... it never occurred to them that we as a industry aren't adding much if any VALUE or expertise to the consumer so why on earth would they want to open their wallets? plus bitter dealers barely keeping the doors open in a collapsing industry tend not to give great cust. service, so it isn't fun. That kills the "word of mouth" advertising that is basically all the industry can afford.
These issues seem to be ones that a competent dealer/reseller would have addressed upon preparation of the regs for the consumer. I don't care what brand we are talking about, anything right out of the box is suspect. "Dealer Prep", the term frequently used in the Automobile Industry, is a perfect example (and it is even itemized on your purchase contract).
It says more about a distributor/reseller, than the brand......
