I have a Escort 8500 X50 and I've always wondered at what signal I'm at danger of being clocked. At full signal? Don't get me wrong, I'm not asking this because I'm one of those drivers that never slow down with a weak signal. I'm actually one of those drivers that brake my car EVERY time I get a weak signal and stay on the look out for several minutes after the weak alert...until I figure out where the radar is coming from. But why I'm asking this question is first of all, I've always wondered about this, and secondly, I was on the way home the other night from my girlfriend's house and it was about 1:30 in the morning. I was on a winding, hilly countryside road and I always have my detector on because you just never know when you are going to need it and I almost always have a heavy foot to make good time. I was coming around a slight curve with a slight valley just passed it...and I seen headlights approaching in the oncoming lane down in the slight valley so I slowed down about 5 mph because you can't go by visibility at night. I was doing 70 in a 55 but slowing down to 65 always allows me a little more of a chance to get down to at least 60 even with a short warning alert. Well a short warning alert is exactly what I got. I braked it down from 65 to about 58 suddenly. Then as I got to the approaching car, I distinguished it as a rolling cruiser. No U turn to come back with blue lights aglow. I'm having trouble deciding if this was instant on or if it was constant moving radar that didn't pick up as early as it should have since it was a curvy and hilly road, not a bad curvy and hilly road though. Most of the instant on alerts I've gotten were at shorter distances from the patrol car then this. So I'm thinking it might of been constant radar. There were no weak signals. Just a strong signal, but NOT A FULL SIGNAL AT FIRST. There was probably 6 or 7 seconds between the alert and the patrol car. The detecting range seemed short even though it was a hilly road which can affect the radar detector...and I'm not so sure it was instant on. This radar detector was bought used off of Ebay but the seller had good feedback. Wonder if I need to send in the unit to have calibration checked? Because it seems like most of my alerts are short warning alerts. What address do I send it in to? Anyways, does this mean he had me clocked at the strong but not full signal? Or not until it became a full signal?
