WOW what can I say I ma jealous at how silent my wife's RX65 stays yet can pick up every threat. I was driving with her today and the RX65 alerted us os K band about 2.5 miles before we saw the officer. Here in my city they use constant on K band which is CAKE to pick up. My V1 goes off all of the time in the city on falses but her RX65 stays quite yet deadly. What an awesome detector it is.
