@Dimitrios-Kanellopoulos Thanks, yes the S5 really seem to suit my needs. I really like it and all values seem to be very close to what I got from the S9B. I did the Nordic Walking on very hard underground without the rubber on the poles, what created a lot of vibration in the poles, which might have also generated a lot of disturbances. Will try with softer ground / rubbers while on street and see how it works. But Suunto really got me! I really like Suuntos interface and the reliability of the watches. Coming from a Polar Vantage, I am really satisfied with both the S5 and the S9B, but I tend to keep the S5 since I am not the Ultrarunner or mountain trail runner and therefore I do not really need all that extra features the S9B offers. Also a big Thank You for moderating that Forums in such a great way!
Cheers Christian
