For your needs (off‑grid, multi‑day, altimeter/barometer/compass plus maps and long battery), the Coros Vertix 2 is one of the best options: it offers very long battery life (up to around 140 hours with GPS), offline topo and landscape maps, and robust ABC sensors.
Battery life is the biggest advantage with a Coros watch. I have a Vertix and with 6-7 hours a week of workouts/runs I can go about a month without charging. And it's pretty old.
"No Feature locking" is not true. Fishing modes are not shipped to all watches, just Nomad and vertix. Also other activity modes are not available on all watch models although it is not a hardware issue
My Coros Vertix is awesome, but it's been a looong time between versions and Suunto has gone way past Coros now in battery life and features. Coros need a new Apex and Vertix otherwise they're going backwards.
Garmin make great gear (used them for years) however lately they’ve gotten stupidly overpriced. I also use Coros and Suunto and they have pretty much equivalent features for substantially less $. Worth a look.
As a Vertix 2 user, I’ll stick with my Vertix 2 😅 I don’t need any fancy features or gadgets really. Just battery life, insane durability, and a good interface/app to use the watch/view data. I have put this watch through a lot in the 1.5 years I’ve owned it—it has zero scratches.. And I only charge it once every few of weeks? It’s all I could ever ask for lol
How much battery life are we talking? I have an OG Apex and it easily gets me through a 100 for half the price of a Vertix. Guess it just depends on what features you're looking for; I want the bare minimum and Apex is great for me.
