Decisions on a Dive Computer

[Centrals]

I am glad I had bought couple of Uwatec computer over 20yrs ago. One has expired but the other one is still going strong. A cheap Oceanic is a back up.
What do I need? Go diving if I could.

I'd been debating getting either a Shearwater Teric or Perdix AI for a while.
I finally went for the Perdix AI for the following reasons:

1. The Teric is a daily use item which needs to be recharged at least every other day. That's too much trouble for a dive computer. I'd much rather have a regular mechanical watch or a smart watch for that purpose. The Perdix you just switch on when you need to use it, so the 40 hour battery life can last for several weeks of diving.
2. The Teric comes with a wrist strap, which to me is less convenient for diving. The Perdix's elasticated straps or bungees are easier to use with different types of suits.
3. If you're caught with a low battery on a dive boat (maybe because it didn't sit in its cradle correctly over night), there's nothing you can do with the Teric. With the Perdix, you just put in a new AA battery, and you're good to go.
4. The screen is bigger, allowing it to contain more info while still being readable, or has generally better legibility (even though the resolution is lower than that of the Teric).

While I like the Teric (a lot), for me the Perdix is more practical as a dive computer. I just wish it had haptic feedback. I switched all the beeping alarms off on mine. That also promotes the good habit of checking your DC more often, instead of relying on alarms to alert you.

I charge my Teric every 3-4 days on a dive trip. Nothing says you need to replace your EDC watch with it. Mine gets put away after the dives, with my Suunto smartwatch being what I keep on my wrist when not diving.

You can put Perdix straps on the Teric, that is what I use.

If you're caught with a low battery on a dive boat (maybe because it didn't sit in its cradle correctly over night), there's nothing you can do with the Teric.

They make power banks with built in Qi chargers that work with the Teric. I carry one everytime. I use it to keep my phone charged in addition to charging the Teric if it needs it.

I currently use 6 different computers, for 3 different sets of circumstances. The only thing I ever change is the nitrox percentage. I do not need an intuitive UI. I grab a box with the correct gear for the day, that is it.

I should have caught this earlier, but you are a dive pro, right? With your own business. Do you not dive daily then? Multiple dives per day? Do you just not track nitrogen loading day to day?
