Hey, I just got a brand new Edge 830 Sensor Bundle. I may be wrong, but a couple of things are bugging me. First, there was no factory seal on the box. Second, the battery was 0% and third, the sensors list in the menu was populated with one HR, one cadence and one speed sensor out of the box. The HR appears to be the one the unit came with. I don't remember my previous Edge 510 to have had this. Are all these things normal or could my unit be a refurbished one? The unit itself or the sensors do not appear to have been used.
