Light GPS clock with defects in the GPS measurement

Hello There,
this clock got myself as a third GPS clock made by Garmin. Previously, I had the Forerunner 205 and 305. Since the lifetime of these watches in conjunction with the price is rather unbalanced, I decided in this case, for a slightly cheaper model. Although I still have a corresponding expectations at a price of 235.

Compared with the other two watches that yes essentially differed only by the connection of a chest strap, the Forerunner 220 is comfortable to wear. Significantly thinner and lighter.

Also, the preset vibration alarm at every kilometer run with a short display of KM-time I really like (but would have probably so to set the other two clocks).

The main point, however, for there are stars from me 2 withdrawal, is the GPS measurement. I largely over the same rounds, I know the distances in and out. The two predecessors, the data revealed virtually. And even with the Iphone / Runtastic app, which I took after the sudden death of the last Garmin, the distances were close to the results of FR 205 and 305th

The inaccuracy in the FR 220 is approximately 200 meters to 10 km running track. Depending on the proportion of the forest, the deviation can be even greater. For a manufacturer, who has worked as a specialist in this segment, I expect for a clock with this award more easily.

Will the clock keep though, as me the expense of unwinding is too high, but if I decide to come again next time for Garmin, is rather uncertain.
