The timing shows / PC is done well and the one with the heart rate monitor. The GPS information is "captured" quickly, even slight movement (recommended to stand still anyway).
Note that I had a small bug on one output (the watch is cut repeatedly), but I found out why: I had changed the heart rate parameters (maximum heart rate and intervals) via the application, but HRmax has not been updated on the watch even taking care of synchronized with the PC. Suddenly, there was a discrepancy between the FC intervals (them updated) and maximum heart rate of the watch which generate an error during exercise. I corrected my maximum heart rate manually directly on the shows and everything is back in order.
We should not be surprised by possible differences between the bike meter (speed, distance) and GPS data. This is not unique to this show (it will be poor with other brands or models), but simply the difference technology. You just know, that's it!
I recommend this product for those who want to practice and get feedback / monitoring the intensity and the training load.
