Maybe a silly idea, but would it be possible to implement tissue status/CNS clock sync between multiple computers (and models - like Perdix and Teric), maybe over BT, so it will be two button presses and done?
Or maybe this can be achieved by syncing dive history between them?
For example you will go on a vacation, will do intensive recreational diving for couple of days (multiple dives a day, light nitrox ofc., with Teric as you want to be really cool), but the opportunity to do some deeper (bp/w + twins) dives will suddenly arise and because you don't want to offend anyone with wrist watch dive computer, you would like to bring Perdix for those dives.
Or you can do deeper first (half a day trip), recreational after (afternoon).
I mean I really like the Perdix, don't consider it obsolete now as it works exceptionally well with thick gloves, you can do bungee mount, you have simple two button interface but wrist watch dive computer might be more appropriate in some situations.
