Just got my V1 and put it in the car for a trip to the grocery store. (Only one in town) My other detectors, cobra and X50, both picked up the opener but the V1 didn't peep.
I also noticed that the cobra picked up the V1 but the V1 didn't notice the cobra
Anyway, I got it cheap so I guess I'll send it in for a tune.
So the 813 is supposed to be a good one?
