With my apologies to Chris, who is at Beneath the Sea and presumably too busy to wade back into this mud puddle for possibly stepping on his toes but let me share my thoughts as someone who has taught the TDI Hog class to more people than anyone else:
Technical diving isnt just more and better gear; its also more and better knowledge and skills. Technical divers have to accept a lot more risk than recreational divers which means that they need to work hard at mitigating that risk. Chris believes (so do I) that all technical divers should have the knowledge and skills to inspect, clean, overhaul and adjust their gear so that they KNOW it is in working order. Recreational divers, not so much.
Learning how to service your own equipment requires dedication, time and money that most recreational divers would be better off investing in becoming a better diver. This isnt like taking a Fish ID or Equipment Maintenance class. Simply put, a technical certification helps to demonstrate that the diver has the need as well the prerequisite moxie to pay attention, put the effort in and be aggressively self-critical. Recreational divers, not nearly so much.
If you think you can learn to service a regulator by reading a book or a manual (or even lots of books) youre bat-**** crazy. There are many critical skills and lots of critical knowledge that can only be learned hands-on and while a book may give you some of what you need to know it simply cannot give you everything that you need to know. The best place to learn these skills is working at the bench with an experienced technician leaning over your shoulder guiding and coaching you, second-best is a structured course like the Hog class where you actually do the work real-time.
Chris has broken new ground by creating the TDI Hog class and a clear path is available for those who really want to learn how to work on his technical regulators. A LOT of work has gone into trying to find a way to responsibly, ethically, rationally and effectively give people a way to learn how to work on their own regulators. That path may not be easy and it may not be cheap but its there and its a quality program. It gets more than a little tiresome listening to all the whinging and scraping about this from divers, especially given the considerable blowback received from local dive shops and other manufacturers about the program some of those folks feel very threatened by the idea. The frustration Chris expressed may have a lot to do with the fact that no matter what he does with this training program, somebody gets hacked off. Sometimes it feels like the caterwauling from the harder-core DIY advocates has more to do with wanting something for nothing than anything else which any technical diver quickly learns is a fools bargain. At any rate, to have to endure sniping from the potential beneficiaries of this effort is disheartening, to say the least.
At this time, there is NO official service manual for any of the Edge or Hog regulators, although I have created a step-by-step manual for the D1 that I give to students who take the TDI Hog course from me. Chris has reviewed it and has approved it but until some details get ironed out, it isnt yet official. Maybe someday, hopefully soon, who knows? If you already know how to service regulators and all you want the manual for is a little guidance, there is a special path that you might qualify for that will skip some of the classroom time. Send me a PM with a list of the regulator service courses you have taken and what experience you have and we'll talk.
Chris is offering a quality regulator at a daft price and is busting his not-inconsiderable balls to provide a level of customer service (including a way for divers to learn to service at least some of his line) that is second to none. My suggestion to all of you who think the Hog program is inadequate is that you find another manufacturer who is willing to do more for you.
In the meantime, if youre in the Chicago area and are interested in taking the Hog class from the guy who actually wrote the only manual thats out there, PM me. Ill only be teaching it a couple of times between now and the end of the summer dive season but there will be more once the lake turns this Fall.
