People talk about HOG and being unable to service it outside of the country. (ie: on vacation)
Since the D1 is a DST & the D2 is a DS4, and there's plenty of Aqualung Dive-shops around the world, wouldn't it be easier to carry around a parts kit and take it somewhere if you don't know how to service/fix it?
Since fixing it wouldn't be a problem to someone who opened a DS4.
I don't know about ScubaMax, are there similar reg on the market that have the same design?
@
Seraphimx: You make a good point. There are a number of regs on the market that look very similar (inside and out) to the Apeks design. I agree that, because of the limited reach of the HOG dealership network, it would make sense for a HOG reg owner to carry 1st and 2nd stage overhaul kits with him on a scuba vacation. Then, it might be possible to take advantage of a local reg tech's knowledge to help fix an issue with the reg. Based on what I've seen on disassembly/reassembly videos of HOG regs, they are strikingly similar to certain Apeks/Aqualung regs. Alternatively, the diver could just bring along another fully functioning reg setup as a backup. That's what I do when I go on vacation.
With regard to having an Apeks/Aqualung-trained reg tech do HOG reg servicing/repairs...
There may be issues with having such work done. First, the reg tech might refuse to do the repairs due to liability concerns. After all, he hasn't taken the official HOG reg training. Second, the reg tech won't have access to the proper reg torque specs and the "official" HOG reg tech servicing manual. That being said, in a pinch, if he's a reasonably competent reg tech, he should be able take the reg apart and put it back together again using Apeks/Aqualung torque specs. Is it safe to do that? I suppose that only someone who (1) understands the working tolerances of such specs and (2) is authorized to work on both Apeks/Aqualung and HOG regs could tell us.
At present the HOG reg manufacturer (
cerich) seems open to the idea of hosting a freely downloadable PDF file of the official HOG reg tech servicing manual on the HOG website. This is a departure from the situation in recent years, when only those who paid for and took the reg servicing class were permitted to have a hardcopy of the manual (and were forbidden to share it with others). I use the words "seems open to the idea" because
navigating to the appropriate page on the HOG manufacturer's website reveals a handful of broken links to the reg manuals and schematics. I recall the manufacturer mentioning that he pays some high school/college kid to do his website maintenance, so perhaps interested parties will have to wait until that kid has a break from school (e.g., summer vacation, Thanksgiving, winter holidays, spring break, etc.). Personally, I don't think that writing a few lines of HTML code and FTPing a couple of PDFs to a server are difficult tasks...but that's just me. (FWIW, I'm not a computer guy at all.) I realize that there are lots of people out there with varying levels of computer-savvy. Unfortunately, in this day and age, having broken links on a company website over a timeframe of weeks (or months?) can reflect poorly on the company's image.
