So you're suggesting that you can optimize the functions of a deco reg as opposed to a stage reg based on depth/mix by changing the gauge?

It would be very interesting to hear explanation why it's not optimal to use same reg for deco and stage purpose.

I have a better idea: why don't you start a DICE forum. DIR types will just leave you alone then.

Don't be offended but if your profile data is correct ("Soon to be normoxic trimix certified") then you can hardly say anything about this subject.

Button gauges don't avoid anything bad.

And create issues like this...

From my limited experience (mainly with MK2s, MK20/25s, DS4/DSTs), with the way the bottles hang (on the left), it's somewhat difficult to see a button gauge on any first stage, not just the DS4s. With a "fulll size" SPG on a 6" hose, one could twist the face of the SPG to an angle that allow clear viewing. It's nice just to be able to glance quickly at a big, clear "display" and not have to touch the bottle or bring it up close to view the pressure.

Trying to keep score here.

SPG on a hose advantages:
Large size and mobility makes it easier to read
maybe more accurate
Has some give since the hose is flexible (bottle joggling anyone?)
allows for uniformity across deco bottles and stage/travel bottles

SPG and hose disadvantages:
Its clunky (?)
Hose is an additional failure point

Button advantages:
its smaller :\
No hose to fail

Button disadvantages:
maybe harder to read depending on size and lack of mobility
Has no give, possible more prone to catastrophic failure do to impact
may be less accurate depending on model

Did i miss anything?

Some of your pluses and minues are predicated on one or the other being "true"

E.g. hose failures don't actually happen - as in leaking needed gas. Sure any hose sometimes delaminates and needs replacing, I'm talking "blow" underwater. Such an event never happens with even a modicum of pre-dive care. And even if it were to happen, the hp orifice prevents the loss of much gas at all, so big whoop. Thus...

the "benefit" of "No hose to fail" does not exist.

What I minute as anal as DIR is about extra failure points and being streamlined and you can't even admit an SPG on a hose has extra failure points and is less streamlined???
