Apart from this small annoyance to delivery, I have tested the Polar RC3 the last Week End: GPS synchronization time on satellites takes about a minute (I'm in the countryside). The different data is then easily downloaded from the dedicated website Polar ([...]) and the cartographic rendering of my course is very faithful to reality, including in forested areas with cover of the GPS signal by trees. All data (speed min / max / average and instantaneous gradients + and -, altitude, heart rate ranges, heart rate min / max, instant, etc ...) are available during the race on the watch via 8 displays various data (information display 3 lines).
The only downsides (if we had to find two in my opinion):
1 / No option to customize displays, but the possible 8 are complete and provide all relevant data,
2 / No backup possible outside the Polar dedicated website (see link above).
But these are only the flats and in the end I am fully satisfied with my purchase, I therefore recommends training computer with GPS and integrated where altimeter 5 stars !!
