First ride impressions. Today I took the device out for a short ride. For comparison reasons I also was wearing my GH625M. Here are my observations.
1. GH625 and GB580 does measure the ride differently.
625M: Distance 12,65 km, Avg Speed: 9,34 km/h
580B: Distance 11,72 km, Avg Speed: 8,66 km/h
While riding I noticed that the actual speed also was different. The cumulate altitude was nearly double measured by the 625M, than that of the GB580.
2. Button pressure. The amount of pressure that should be applied on the buttons is fairly high, when riding - and the mounting with the plastic-strips, does give some flexibility. I would like some buttons, that are a little easier to press - and a mounting solution, that is less flexible.
More to come....
I don't know which of the devices that are most accurate - but they surely aren't agreed.
