Hi Tech Heart Rate Monitor With Gps Sensor

I do a lot of cycling here in Chiang Mai. I'm selling My Polar RS800CX Multi with the GPS sensor that can be reviewed on Google earth. It's just a couple of months old. Super easy to use and has endless training/fitness features. Includes training software, infa red computer interface, Polar W.I.N.D. GPS and Heart stap transmitter. I have just bought another Polar computer and don't need both. Anyone interested can let me know. Thanks
