So, somehow checking your SPG is fine, but a console is a PITA? Sounds like one can either argue for a totally wireless air-integrated wristmount, or a console, but this something in between seems the worst of both worlds.
When I navigate, I am constantly looking at my compass. When I dive, I'm checking my depth and time on a regular basis. However I check my pressure maybe three times a dive, and sometimes not at all after the initial splash if it is a shallow dive. I think newish divers and air hogs may constantly chimp their pressure, but not so much with more experienced divers who are comfortable with their air consumption, and profile.
I do have an air integrated wireless computer, but I don't think that is a must have, more of a nice to have. Yes, I find unclipping and then clipping a console constantly to check depth or time to be a PITA. I suppose one can mount a console with a bit of hose extended so the clipping may not need to happen, but generally not for navigation. This is personal preference, but most divers I know agree, and tend to use wrist mounted gauges.
Why are wrist mounted gauges the *worst* of both worlds?
As to wireless integrated computers, I know that initially there were issues. I have an Aeris Epic, and after diving with it for over two years, I've replaced the watch battery once, and the transmitter battery is still original. As this is user replaceable, it was not big issue. I've replace the battery in my Aeris Atmos II every two years as well, and it is not wireless. It is rare that I loose my wireless connection. I've noticed it has happened on two dive out of over 100, and only happened for a few seconds. This based on the downloaded dive logs as I did not even notice when it happened.
I'm not sure your criticism of these units is justified as YOU did not purchase one, so you have no experience with these units. I know just as many folks that have had issues with computers that were not wireless air integrated including air integrated consoles. To each their own, but don't be too quick to criticize a type of computer you don't dive.
