In need of sock puppet
Polar's 720i uses a nice infrared link, that's fast via their USB-iRDA link. It downloads your excercise files into the Polar software, not web based, allowing you to build a diary of your workouts. You can set-up excercises on the PC and upload to the watch as well. With speed and optional cadence sensor, and the potential of adding the Power sensor, the 720i provides a robust, reasonably accurate HR-based workout tracking system.
