Drove through TN & AL today with my new RX65 ran into a THP car running c/o 35.5 it was stationary on the opposite side of the road on the shoulder with the rear antenna on targeting cars in a construction zone. The RX65 first alerted about 1/4 of a mile before it and continued to alert for about a 1/2 mile after passing it. Then in AL I ran into four different patrol cars running c/o 34.7 I had about 4-6 seconds of alert @70 mph before patrol cars came into view. No I/O encounters yet. so far I am impressed.
