A:Suunto’s Quest ($300) starts life as more of a watch than the Garmin. It lacks GPS, but offers a more compact, wrist-friendly profile, and can be set up for use as a running or cycling tracker. It monitors heart rate, calorie burn, intervals, and all that good stuff. A USB stick transfers data to a computer for detailed analysis. And it’s rated to 100 feet for water-resistance, so it’s fine for sports on the water’s surface.
