I use the Suunto Ambit 3 Run and absolutely LOVE it! I have had it for a little over two years and worn it about 2,500 miles. It has never lost signal, even deep in literal wilderness. The battery hasn’t lost a minute of its 10 hour expected life, and you can charge it while you’re running. The charger clips onto the watch while it is on your wrist, so pack a power bank and you’re ready to go! I can upload routes to the watch and get turn by turn directions while on the trail. But My favorite feature has to be the track back function. When I’m out and about and get lost (I cant resist exploring the animal trails) I can choose between it back-tracking me the same way I came, or an arrow will come up on the watch and lead me back to my start point in the shortest possible distance. Those two features could literally be life savers when you’re out and lost.
