Enough wires already! The Scosche myTREK ($130) is a wireless pulse monitor that attaches to your wrist or forearm and tracks your pulse, training type, calories burned, speed and pace, while sharing data to your iPhone or iPod wirelessly. The Bluetooth-enabled Armband produces real-time pulse monitoring. The device functions with the myTREK App to manage your current and past training sessions and get the most out of your workouts. Here is a video of the Scosche myTREK.
