A autonomy that puts others on knees
Let’s start with the thing that kills: autonomy. 45 days in normal use, and 90 hours in full GPS. You read well. When I tested this in trek in the Pyrenees, the friends with their Garmin Flippent serious at each bivouac while I, quiet, I had another 80% battery after 5 days. I also made a little comparison with the best GPS watches for mountain biking if you ever interest you.
A touch screen that finally responds in the rain
The screen, let’s talk about it. Unlike the previous version which would grace severe under the fleet, Coros finally solved the problem. Sapphire glass is unbreakable (or almost), and the touch screen reacts even with gloves or in the pouring rain. On the other hand, the brightness in full sun is still not that … Too bad when you are supposed to use this watch in the mountains.
Sports functions that send heavy
For athletes, the vertix 2S takes everything you need: precise optical cardio (except when you sprint as a deraction), oxygenation measure, barometric altimeter and a cartography that improves but remains below what Garmin offers. Navigation is rather intuitive with the rotary button, even if I struggled the first days.
Recup data is now much more relevant. The thing that taped me? The precision of the sleep tracking which tells you squarely when you have too picked the day before. I tested this after a slightly watered evening, and the watch gave me catastrophic stats. Beautiful scam for your conscience!
