My RX65 continues to impress me on a recent trip picked up 34.7 for two miles with patrol car facing same direction as me parked behind 18 wheeler, continued to receive alert for about one mile after passing. Another encounter picked up k band from moving patrol car passed it about one mile after inital alert, I was going about 74 mph. The Rx65 has the best combination of filtering and detection range of any detector I have owned.
