I haven't seen this discussed here, only a passing reference to v2…
It's $50 and manufacturer indicates 2.3 oz. Amazon reviewers agree that the user instructions are terrible. But there are no comments indicating poor build quality or function (except a couple that don't understand that altimeter & barometer both measure air pressure, which even I know). Seems to be cheaper than watches that do the same, and I won't ever wear a watch anyway. I can probably figure it out despite the terrible user instructions.
Intended mostly to replace my plastic compass plus cheap Casio watch (I don't wear a watch so invariably forget to bring one and have to purchase again from nearby Walmart/Walgreens; there must be 100 of the damn things in my kitchen junk drawer). I'd trust my plastic compass more but it's no big deal navigating the Sierra with a map only if it comes to that, and I'd bring a backup compass anywhere that it mattered. Altimeter/barometer would be a fun extra for me.
Does anyone have the Generation 3 and does it work as it should?
Are there alternatives I should consider?
