Much better than my Polar RC3 GPS HRM

GPS fix much faster quavec Polar RC3 GPS.
Average Pace calculated correctly.
Ability to display the% HRR (Heart Rate Reserve) and not only the% of maximum heart rate.
4 screens with 4 steps, each fully configurable.
Data cable / USB charger very easy to connect to the watch.
Sound level of audible alarms for ambient noise and the presence of a vibrator.
High resolution color touch screen.
Firmware updates available on the Garmin website and easily installed by the user.

In short a complete satisfaction so far.
That said, the budget is not really the same compared to the Polar which is still close to 170 EUR cheaper.
