Active or not, he certainly could work on his approach
. His last post did nothing to help the reader by clarifying what NCadiver was confused on. He simply took the pompous approach, claimed to know it all but offered to share none of it.
I don't have an obligation to share with anyone, when I choose to do so it is typically with people who are interested in learning. Perhaps OP is the exception or perhaps I was just indulging in a little pig wrasslin' in the mud.
Learners ask questions, politely. Although phrased as a question, what OP posted was a technically fallacious and grammatically ignorant rhetorical taunt undeserving of a response. He didn't join this thread looking to learn, he came here looking for a fight - what us old-timers used to call trolling. Despite that, I gave him some advice that I thought might help him - or others - on the path to learning. If I wasn't on point enough for you, consider that it might be necessary for OP to do some back-filling and un-learning before he is ready to move on to more advanced concerns. If I wasn't friendly enough to suit you, well, I'll leave you in charge of giving him the snogging you think he deserved.
As to my credentials, I first stated diving in 1970, these days most of my diving is deep technical wreck diving in the cold waters of the Great Lakes. I also work in the repair room for a very busy dive shop. Like most repair guys, money isn't the primary reason I work on regulators. Instead, I enjoy the focus it requires, the fine hand-work and I find a sense of satisfaction and relaxation from the process. I work on many hundreds of regulators every year and have been through almost every manufacturer training program out there, many of them more than once over the years. I'm also an instructor for more than one agency and have taught many hundreds of students how to dive. As Boss Hog pointed out, I've even taught a bunch of folks how to work on his regulators, maybe more than anyone. Simply put, I
am an expert on the subject. It's entirely possible I'm also a crank, at least occasionally. Certainly, I don't suffer fools well.
If OP has questions, let him ask them nicely. Otherwise, he can go jump in a lake. That's not a bad thing, is it?
