Hello I am now in the second Enduro 2 since September the 3rd when I made the first purchase, the reason is that when I do a workout in a close 700 meters stadium I get irregular track readings of the GPS. It appears that the device losses the signal and it shows my position scattered all over almost 50 meters away from my real track. The local dealer changed the device with a new one which operated perfectly for a week however today the problem reappeared! I filed a complaint to the support center with my Garmin Connect Account's maps of all the work outs in the same place presenting the issue. Apparently it is not an issue related to a particular device. I have the Run mode with all GPS open ( multiband) and data collection every second. Is there any tip that I should follow to avoid this irregularity? Thank you
