I think the Garmin Forerunner 305 has the potential to really help out a runner but i don’t thing the heart rate monitor is very accurate. I’ve done a manual count after a heavy workout and compared it to the garmin and the garmin is way off by as much as 20 to 30 beats. That bothers me that I’m not get accurate data. Sometimes the heart rate monitor won’t even pick up my hear beat, so I spend several minutes during a heavy work out adjusting the band to see if that helps. I wish it would also tell my how many calories I am burning even if I’m not outside working out. It’s functional but I wish is was a better device.
