Question First Dive computer Suunto D5 or Garmin G1?

[inquis]

I find the dedicated “tec” style ones like the peregrine or perdix offer far better functionality when actually diving

What "far better functionality" did you have in mind?

TBH in the past, I wished my Perdix had a stopwatch available in Dive mode like my Teric does. The Tag/Bookmark feature is pretty cool as well.

The display is a big one, ease of function underwater. For me I find the peregrine/perdix far easier and more functional when actually diving

Functionality shared with the Teric, then.

The biggest difference between the form factors in my view is there is more empty space on the rectangular models. I wouldn't call that a functional difference, but it's certainly a personal call whether that is more or less desirable.

OP is comparing rec watch-style computers, hence I suggest Tern (TX). FWIW that also happens to be my preference too.

Peregrine and Tern have basically the same functionality, so it comes down to preference - neither is “better”. FWIW the boxy-style Peregrine is much much larger and wastes a lot of space on the LCD display. The Tern is wearable during surface intervals and packs more info into the (much better, brighter, denser AMOLED) display - and is still easy to read clearly.

I see the point of the Peregrine if (and only if) you need the extra battery life, need fewer bigger buttons (gloves), or have truly terrible eyesight.

Teric / Perdix are of course a totally different category
