I just ordered a Valentine 1 a few days ago and I am supposed to be recieving it tomorrow. Im very excited about it. Just got a question about it. Lets say im driving down a straight road and it is straight for ten miles, along the side of the road there is a state cop backed up against a fence and is shooting radar across the road at an angle. If im driving down this road, about how far in advance is my V1 going to go off before I actually get "under" the radar.
