You seem to have fixed on horseless carriage as a definitive exemplar of neologistic word construction. It is not. Just think of all those propellorless aircraft and painless dentists.
Propellorless aircraft - an aircraft that replaces the propellor with something else
Hoseless pressure gauge - a pressure gauge that replaces the mechanical connection between tank and sensor - the HP hose - with something else (a radio connection).
Just to be absolutely clear, I'm fully aware that wireless is the common vernacular, and that no one uses the term "hoseless" in conversation. In fact, "hoseless" is so rarely used, that my autocorrect keeps changing it to "noseless"..!
That still doesn't make it correct.
There is far more than the simple replacement of a hose with a transmitter involved. Something much closer to a sea-change has occurred.
I didn't say it was simple, but a wireless AI computer replaces the hose connecting the first stage HP port to the pressure sensor with a transmitter and receiver connecting the first stage HP port to the pressure sensor. The fact that a brass and glass SPG and a computer with AI use different types of pressure sensors doesn't change the terminology that refers to the link.
The correct term is wireless. The connection is electrical, not mechanical.
Once again, you don't seem to be grasping my argument. It's fine if you disagree with me, but you should at least understand what I am saying.
To say something is "wireless" means that a connection that was formerly by wire is now by something else (i.e. a radio link). So "the connection" that was replaced by the radio link, is, in this case, a mechanical connection. While a wireless connection is obviously electrical, what it replaces is mechanical. Not sure why this is not clear, but perhaps I am clueless or artless in my prose.
On a more positive note, I was greatly amused by your 'air integrated consoles' reference. I don't think I've seen a console in use by an experienced diver in quite a few years.
I'm sorry to be witless, carless and senseless. But I'm glad that I'm amusing!
I have no idea what the fact that consoles aren't used by experienced divers has to do with this discussion. Perhaps you thought that I was recommending them or something?
There are, to my knowledge, three ways of reading your tank pressure while scuba diving - (1) an analog SPG on a hose, (2) an AI computer (or other digital SPG) on a hose, and (3) a computer with wireless AI (typically wrist mounted). I was distinguishing #3 from #1 and #2 for the purposes of the semantic discussion of "hoseless" vs "wireless".
What term would you use for #2 that would be preferable to "air integrated console"? I'm happy to use that one if you prefer.
