Lovely as it looks - my eyes are too old for this.
I just bought a Perdix AI to replace a 2006-vintage watch-style AI computer that was perfectly fine except that I basically can't see it anymore. I never really could see it using its backlight, and on night dives had to angle my light just right to be able to see the face without glare from the glass.
A few days after getting the Perdix, I spent a couple of weeks diving in Cozumel and have been extremely happy with the Perdix AI. It's a much better computer overall (duh), but as I said my old one met my recreational open-circuit nitrox needs apart from legibility. I found the Perdix AI highly legible under all conditions and very easy to use (including the "oh, crap - I forgot to set my nitrox mix!" moment as I hit 10 feet on my descent, which would not have been fixable during the dive with my old computer). I like those big buttons, even though I don't dive with gloves.
From the pictures I think Shearwater appear to have done a great job organizing how information is displayed on a smaller, round screen and suspect I'd find the AMOLED display legible underwater. It's significantly less tiny than my old watch-style computer, which I think is a good thing. It's still not something I can envision my wife wearing out to the chicken coop, though.
As much as I love toys, especially dive toys, I personally think I won't be replacing my Perdix with the Teric for several reasons:
- It's still a smaller screen, as well laid-out and visible as that might be
- The buttons are smaller to fiddle with
- There are twice as many buttons to fiddle with
- Charging is appealing, but
- That means I either need to travel with a charger or buy one for the US and one for Cozumel (where electrical things don't survive well)
- I love the idea of worldwide-available AA batteries, of which I can have a fresh spare in my save-a-dive kit
- It looks nice, but there's really no chance I'd use it to replace any of my everyday watches
- I really don't wear a watch these days, and I have some really nice ones
- When I was using a watch-sized computer, I never wore it around Cozumel because it was my dive computer
- Cheap, tough watches are readily available. A replacement computer with my current tissue status is not.
While it's just fun stuff and not important for diving, the different colo(u)red bands and matching faces are kind of cute. The advantage of charging over those easy-to-replace AA's is I can't screw up a battery replacement and flood the computer (but I still don't want to have to get another charger for Cozumel).
I think there is a market for this sort of thing. If I didn't already have a Perdix, I'd probably give the Teric a serious look. My wife really liked the Perdix, but it's really big on her arm so she might prefer the smaller form-factor of the Teric.
