While the Teric has a lovely screen I am not sure this is really true. The D5 and Garmin both have transflective screens. These work both by having a backlight and by altering the colour of light that falls of the display. This means that they are still good in bright sunlight. Not as pretty as a pure backlit screen in a dark room or a bright backlit screen in shade, but effective.
While Shearwater have done a great job selling the Teric I am not a fan. I prefer the format of my Perdix. If I wanted to spend the money on a ‘watch’ I’d want it to measure my bicycle rides, count my steps and so forth. Shearwater will never be able to compete with Garmin doing that.
Here the D5 is half the price of a Teric. It does everything anyone could want from a dive computer except Helium and CCR. If it did Helium I would be slightly tempted to buy one as a OC backup but really I’d rather blow that money on the Garmin. Since I don’t REALLY need either I will wait until totally overtaken by the need for a new toy,
I know I am a broken record, but unless your name is Stuart a particular dive computer does not bring bliss to your dives. They are all pretty much equivalent, especially so for newer divers.
Obviously living in the Middle East, I'm very aware of bright sunlight and screens. But because my experiences are in an extreme climate I tend not to focus on them because for most people they're not applicable.
When I first inspected the D5 and Teric side by side on dry land, I was disappointed by the clarity of the D5, but then I'm used to the Eon steel and it was much brighter than most divers would experience. The Teric (on the surface) was certainly clearer to read in my opinion
Thant said my Perdix is very disappointing underwater in teh shallows, because the screen is highly reflective. It requires a conscious effort to turn your wrist to get the optimum viewing angle, where as my Eon is easy to glance at.
I also prefer having graphics rather than numbers as the primary display. Much like when you glance at your car's instruments you normally take in the position of the needle rather than the actual number. Unless I'm re planning under water I don't care what the precise pressure reading is, rather am I at full, half or getting close to quarter remaining.
Like you I'm not a watch format guy, I'm also very ambivalent on the Perdix, sure it's capable but especially here (on SB) it's over hyped to a certain extent. As long as a computer could gas switch between a couple of mixes, I could make any dive I do on it. Would it be a satisfying user experience - probably not especially if I got frustrated trying to figure out a different menu system, But from a practical stand point if it was a choice between dive or not, it wouldn't be an issue nor limitation
I agree wholeheartedly about the price difference, indeed I've chuckled many times when people have used the buy once cry once example, except when Shearwater bring out a new product then its a rush to upgrade. Their money their choice of course. I brought the Perdix on a whim because I wanted to see what the fuss was about, not because I needed it nor because it gave me any additional functionality
Unless one computer dies, or something game changing (rather than nice to have) comes out, I don't foresee me needing to change out - perhaps when we finally get the Eon Steel upgrade, if I think its worthwhile I might buy another and use my Perdix as a spare. Who knows
