Do not understand some recessions

Since I'm only amateur athletes and mainly run on the treadmill at the gym, I also did not need a professional device.

Some recessions have me really confused here, because disconnections would have been for me (even in this entry-level) is an absolute no-go.

These dropouts I absolutely can not confirm until now no dropouts! (Only if I completely put forth his hand, but who does that while running?)

The zone indicator is how I find very handy and most importantly, the heart rate is great for reading.

Did the way thinking if I take the Polar 100, which costs about 60 euros.

Until now I do not regret at all not my decision.
