FS: Polar RS800SD HRM/Speed-distance Watch

This is the best non-GPS speed and distance HRMs out there! I am just too simple of a person to benefit from it. It was lightly used for 2 months, in MINT Condition as well. I baby my gear. Comes w/ watch, S3 stride sensor, heart rate strap, polar training software. Has alot of features: run cadence, HR zones, stride length, program intervals, pace per mile or km and a lot more.
retails for 499 asking 300 shipped to your door. Saving 200 bucks!
