Lots of features... if you learn
Had this watch now for around 1.5 years. I mostly just use the altimeter function and haven't really tried to figure out the compass/barometer parts because they're so complicated. I'm sure I could learn the functions but it just seems too difficult, even after watching a few videos.
The altimeter is usually off by 100ft and has to be calibrated at every trailhead (and at every possible elevation marker, if you really want accuracy, which defies the point...). Also, the battery screw on the underside of the face was nearly impossible to take off.
On the plus side, it looks sweet, is very comfortable, and the basic functions are very useful.
