The draw: Multi-sensor capability from GPS to cadence
Like the Garmin Forerunner 910XT, this versatile training tool can capture swim, bike and run data. Unlike the Garmin, however, GPS capability is an extra—you’ll need to purchase the wireless sensor separately. Other add-ons include a stride sensor and cycling sensors for speed and cadence. One unique feature is the ability to read and display heart rate in the pool. The watch has a comfortable, barely-there feel on the wrist suitable for everyday wear, and the battery life is a lengthy eight to 11 months. The continual display of heart rate zone kept our tester on track during workouts, and navigating through the different modes was simple. Though you’ll need the accessories to maximize this device’s full capabilities, the tradeoff is an impressive arsenal of training data that you can upload to Polar’s training site.
