Magellan Echo

Alone, the Echo, which had the best battery life of our test, displays only time and date. Paired with a phone, and its own app or one like Strava, it displays pace, distance, and time, lets you scroll through songs, and gives directions. A utility app lets you customize it all. "The one to own if you run with a phone," said one tester. [$145; magellangps.com]
