Ironman Triathlon BodyLink System Heart Rate/Speed/Distance The Timex BodyLink System was great in it's day. I only bought the SF891 to replace a unit that I had lost so I could sell a complete Timex Bodylink system on ebay. The associated software was also great in it's day. However, it has not kept up with Garmin line, and the 405CX carries out all the same functions in a single watch that required three components for the Timex system. The Garmin also comes with great software. The Garmin's GPS antenna is far more sensitive than the Timex, and can synchronize with the satellites indoors in areas where the Timex lost contact, an extremely valuable feature for cold-weather running. I got a better price for the Garmin 450CX on ebay than was available on Amazon.
