Wow I learned something today: "HP hoses basically don't fail". Damn I wish I knew that before, because the only hose failure I've ever experienced was a blown HP hose. I KNEW I should have bought one of them there DIR hoses.
On a serious note, I do appreciate the answers, although stating that DIR will never change to accept a new technology at some future date sounds a little presumptuous to me.

OK I just re-read the entire thread, and could not find such a statement. Could you please point out the particular posting that makes that claim?

Dumpster, ignoring your snide comment in the first paragraph, where did you get "stating that DIR will never change to accept a new technology at some future date" from?
I think you are seriously missing the point about DIR but that is okay. However I don't understand why you chose to waste your time and our time asking these questions in the DIR forum and then ignoring the answers?? If you want to ask questions and get legit answers, fine, if you want to troll, try another forum.
Personally, I got tired of replacing 6" hoses that were weather checking from the tight bends. They were at best a crutch but an acceptable one as they were the best option available at the time.
In addition, a 2" or 2.5" SPG on a short hose presents several line traps and is generally more exposed and prone to impact.
In the past I agreed the smallish 1/2" button gauges were indeed too small to read easily under water. However the current crop of 1" button gauges are quite easy to read under water - and I have 43 year old eyes. I suspect the younger DIR divers can see them at least as well. You can still see them just fine when you breathe down the reg during the gas switch.
Whether your particular reg points the gauge in the right direction is another issue. Personally I have no problems with the standard Mk 5/10/20/25 layout.
In my opinion the functions of deco regs and stage regs do differ in terms of both depth and mixes used. Can one reg do both? Yes. Is it optimum? No.
Also, I am suggesting that all SPG's are potentially innaccurate. What I am suggesting in terms of pre-dive checks is to check the deco tank(s) pressure(s) with a dedicated and known to be accurate pressure gauge (not an SPG) prior to the dive.
What I am also suggesting is that we actually advance our configurations and procedures as equipment evolves rather than blindly doing only what was done in the past - which apparently means I am not DIR enough to satisfy those DIR divers who are thoroughly (overly?)indoctrinated.

It is clearly implied when you post that no matter how readable a button gauge is not DIR.
If readability is not what counts than what? It is not DIR becasue it does not have a hose?
The point being made is that an SPG on a 6" hose was the best availabel option at the time - that may no longer be the case. If you fail to consider that, then you are choosing to be overly rule bound and not open to new ideas.
That said I agree with you, I don't feel being DIR means you have to be resistant to change or that DIR will never accept change. That allegation can only be applied to individual DIR divers.
Just a thought, but I suspect one of the issues that is causing disagreement here is that few of very conservative variety DIR divers have ever actually experiemented with or used a 1" button gauge in the water and are repeating an older doctrine expoused by an instuctor, text book or other "authority" based source rather than through personal experience. GUE by virtue of its status as a training agency tends to push a particular and largely fixed set of procedures and configuration that don't change until the powers that be decide to change them. I contrast the pre-GUE brand of DIR was never opposed to experimentation or evolution by ordinary divers which makes sense as it was never affiliated with a certification agency, instructors, etc.
Consequently what is an appropriate "DIR" response, depends on whether you view this as the DIR forum or the GUE/DIR forum.

), button gauges are not DIR - no matter how new, large, or readable they are.
When I read this, I interpret it to mean that "button guages are not now, nor will they ever be, DIR."
If I misinterpreted the meaning of this comment then you can set me straight. My intention was not to be a troll. I actually purchased a number of the guiages this weekend for very cheap, less than $13 each, shipped to my door.
I am hoping they will be sturdy and will not require maintenance like the spindle of a standard pressure guage does. I was also hoping I would not hear any really good reasons not to use them. So far, I'm feeling like it was a good purchase.
Edit: you will also note that I am not arguing that these guages are better, I won't know for a few years at best.

Ok, I understand, it needs to be on a hose , no button gages , but I dont understand this ... ... "No matter how big they are"
but how about 2" gage? or does it need to be a full 2.5"
Edit: finally .. because button gages, or 1" gages, are not graduated in 100psi increments .. thank you Bismark

One more time:
Button gauges do not have the accuracy required. I have yet to see one in graduations of 100 psi. Please post photos to show this on a one inch or smaller face where the needle itself does not obscure at least several hundred psi if such an item exists. You may chose to calculate thirds at depth (wrecks, caves, whatever) with a button gauge but you won't be diving with me or anyone I know.
Also, if you want to be insulting as you are in the last part of your post, I suggest you leave this forum.
