Comparsion of the Garmin Forerunner 310XT vs the Polar RS800CX PTE Premium - regardiing only the size and Design. If you like I'll do a real comparsion in detail. For now I can tell you: If you are a Thriathlete, you probably already own the 310xt. For all others: The Polar does work and will give you very detailed information about your performance - but: I hate all the batterys, the clumsy software without Mac-Support, the infrared data-transmission. If you want to get hassle-free information on speed, heart-rate, track and distance - look no further the 310xt will exactly do this. You just need two things: the 310xt and the heart-rate-monitor. When you get close to your computer, the data will be uploaded instantly to the garmin Website, where you can do a better research on your data. So: my recommendation is: Garmin Forerunner 310xt
