This is one of the way I see the tech requirement. HOG regs have a two year service interval, as a rec diver you probably have only one or two sets of regs. If only are overhauling one set of regs a year or one set every two years it is not enough to keep your skills up. Most tech divers I would assume would have a min of four reg sets(2 back gas, 1 stage, 1 deco) and probably more so you will be doing a couple of overhauls a year. I don't think you could get by the tech cert thing either as the class is run with a TDI cert at the end, I'm pretty sure they would want to see all of the paperwork. I just signed up for the HOG repair class at Beneath The Sea that is run by DRIS and one of the requirements when you show up the day of the class is copies of your tech certs. If I had only one set of regs I don't think I would be taking the class as it is not inexpensive. The HOG class is $250, My ScubaTools order for specialty tools was $250, and Beneath The Sea is a four and a half hour drive for me so I'm figuring around $75 in fuel so I'm up to just under $600 for the class. I'm an auto tech by trade so I already have all of the industry standard tools and only needed the reg specific tools, I also already have the reg savvy book. If I didn't have some of the necessary items already I'd be around $800 for the class. I'm a tech diver with seven sets of regs and I'm also kind of a control freak so I don't want other people touching my stuff, hence I'm taking the class. This is an undertaking that I don't think would be worth it for a diver with only a couple of reg sets.
At issue here is
not whether the cost of taking the class, anticipated number of overhauls per year, or the number of regs owned makes it "worth it" for the student.
The problem, which has been articulated time and time again in this thread, is that tech certification has absolutely
nothing to do with reg repair.
Official reg servicing techs for other reg brands do
not have to have tech certification. What makes HOG regs so special?
Imposing a tech certification prerequisite on the HOG reg repair class makes no sense at all.
If TDI/the HOG manufacturer wanted to ensure that students in the reg repair class were well prepared for learning the servicing procedures, they should have put in place a
relevant class prerequisite, e.g., taking a pre-test on reg design/function based on the "Scuba Reg Savvy" book.
I understand that TDI is a tech instructional agency. TDI must offer at least
one introductory tech class (Intro to Tech Diving 101?) that has
no tech cert prerequisite. Such a class presumes no previous tech cert/training. The HOG reg repair class should be offered similarly (without tech cert prerequisite).
Please understand that similarly minded recreational divers prefer to exert a high level of control over their regs. In fact, I'd argue that
all divers would benefit from learning about how their regs function. Not only does this give the diver insight into troubleshooting reg issues but it also helps direct how he/she conducts pre-dive reg function tests. Enhancement of pre-dive gear checks is an extremely valuable side benefit.
Unfortunately, the tech cert prerequisite precludes motivated, mechanically-minded recreational divers from enrolling in a HOG reg repair class.
