I have had an 8500x50 for about 3 years now. I got it used from a friend and sent it to excort for service when I got it because it was not performing well. After I got it back it seemed to work pretty well.
This summer I have had an hour commute with lots of cops along the high way. Most of the time the detector would pick up the cop, but only with just enough time to hit the breaks before seeing him. The past couple days it has not even gone off until I'm almost next to the cop, making it completely useless because I have already seen him by the time it goes off. I don't think they are using instant on either because the detector keeps going off for about 5 sec after I pass the cop
Is there anything I can do to increase the sensitivity or get it working better again besides sending it in to Escort. Three years and then needing service doesn't seem very good to me.
I may just buy a V1 and sell the escort as I hear that they are better for highway driving and I do a lot of highway through rural areas.
