I installed a rear NetRadar antenna about a week ago and in that short time have relaized just how nice the "arrows" are. Being able to tell when you have passed the radar that is on other side of the barricade is fantastic. Knowing that there us a local LEO catching up with you is even better... So after a week I have several "able to resume normal crusing speed" storys and one save - I was moving fast, he was moving a little faster. The rear signal kept getting stronger and I paid attention. So now I am hooked on the arrows.
