In addition to having the latest firmware amazingly accurate recording of the track convinced me above all the opportunity to plan in the supplied software "training center" training (z. B. Interval Training). The procedure is clearly even the most complex, nested steps: I always do in training, what to do. And when I'm too slow, is equal to the Requesting message "faster" or at rest "slower". Often I also use the opportunity to create on maps my routes, I then expire using the Forerunner - this is great especially in unfamiliar cities or cycling (separately available bicycle racks), take a look at the card during walking / driving ID R. superfluous. The measurement of the heart rate is smooth and precise - no difference to my Polar RS200sd clock, the Forerunner Chest Strap wears - in my opinion - even more enjoyable. A small deduction is made because of the desolate height measurements which are based exclusively on GPS data, barometer measurements were it more accurate, so this feature is currently not to use (but Maybe that helps a firmware update in the near future)!
