Seems like what your computer outputs is a spectrum of outputs...there are the static displays, flashing displays, flashing colors, beeps, vibrations.
I get it that beeps are annoying to other divers, or so I'm told since I can't her them. In fact the only way I know my computer is beeping is if I look around and everybody is looking at me. That's the problem with beeps; they propagate through the water column. Maybe vibrations are better than beeps?
I get it that someone in a drysuit is not going to feel the vibrations. So they learn to look at their computer perhaps more often. Most, myself included, do not look at our computer very often if the interest is gas pressure. Unless something goes wrong, after thousands of dives in varying conditions I have a pretty good idea of how fast my gas gets used up, so checking the pressure is very much about seeing if everything is OK. Same with depth; unless I'm awfully close to my MOD it only gets looked at if I'm varying depth a lot. Someone posted about being on a boat with a max depth of 100 ft; yes, you stay away fromn that but all the input you can get on your depth is good....and if you have to keep staring at your computer while at 95 ft then why are you diving...isn't the idea usually to look around and see stuff?
So, your computer has this spectrum of outputs; why draw the line arbitrarily at flashing colors are OK but personal vibrations are not?
