Suunto Ambit3 Vertical
Finally, a full-featured GPS watch that cares about vert as much as you do.
Brand: Suunto
Model: Ambit3 Vertical
Features This waterproof GPS watch was built with the peakbagger in mind: In addition to normal tracking (GPS and GLONASS reception), you can plan climbing-specific missions with the built-in altitude profiles. Also cool: You can catalog a year’s worth of ascents. If you like multitasking while GPS’ing, you can send your phone notifications to the Ambit3.
Size “It’s thin (a half inch) and sits flush against my wrist, unlike most golf ball-size GPS watches,” one editor says. “But I can still read it when I’m jogging.”
Battery life It runs for two weeks (a days or so if constantly tracking).
