Picked up an I/O hit this morning on my new 8500 X50. I drove for 1.5 miles before I had to turn off and still hadn't seen the LEO. The PO was using the gun about ever 2 seconds. Wish I could have kept on the road to see how much farther away the LEO was but had to get to work. Using Spec mode for a while to see what Ka guns Austin uses till I go back to Expert mode. I was impressed with the range of this one.
