I bought a used garmin vector 3s.
When I calibrate it to my headunit, I found that after calibration it gives torque readings. They seem fine when the reading is present ( -0.03, + 0.05) but every 3 or 4 or 5 readings depending on the time I get "--" for a reading. Is it normal for that to be so frequent or am I getting disconnects. When i used it concomitantly with my trainer I got some lower numbers initially and had oocasional zero powers. I opened it and put the battery in again and re-calibrated everything and had numbers that overlapped with the trainer. However after the calibration I still had the "--" torque reading somewhat frequently. I am just wondering whether this is a bad sign and I will be getting the drop outs reported in forums down the line? I am asking because if this is normal behaviour I will keep the unit. If it is not, and usually you get actual readings far more frequently I will not...
