I have the bel vector 985, very very happy with it.
I guess the big thing about the V1 is it has direction arrows to tell you where the threat is coming from.
As far as I am concerned, I don't really care what direction or where the copper is, I am going to SLOW down regardless of if he is on the left side of the road, right side, on a bridge in front of me..
Does it really matter
I paid 300 dolla at Circuit City, needed it the first day I got the car
Good Luck and happy shopping
