So I was on a road trip... 100 miles, no biggie. with my 8500 x50 still in good shape.
I was pulling 100 ... 110 on I 10 East heading towards tucson from phoenix, a white 2 door mucury came up from behind and was on a crapbra.
I forgot which model he was on, but I was surprised he picked up some sort of K band....for some 200 ft.
the 8500x50 is just a lot better.. now onto a LI quad interceptor when I get some serious $$$
