Hello,I've had a Sigma 509 for almost 4 years and love it ! About a month ago, however, the velocity became very erratic (going from 17-18 mph, down to 4 to 7, but then bouncing back up to expected road speed. Lately the velocity is zero the majority of time. I've checked magnet distance on wheel to frame and that the same (<5 mm). Any other guidance ?Thanks !

I have had the unit for a long time, no problems.Did 100k Sat 15th Aug/time 4hrs, results through a timing chip.my Sigma read 89K 5hrs 15mins. I did zero my distance and time before started.Do I need to reset from scratch,(I do not have instructions) or is it more serious.
