I was on the 40 this week heading to the Colorado River on the Nevada/Arizona border and got an 8.1 mile Ka 34.7 alert ... my longest so far. It was even more impressive considering the cop was moving towards me the whole time. So figuring 70 mph each, that was about a million miles on the range (don't feel like doing the math but it was good). The Redline dropped the alert a couple of times, but that was due to terrain I suspect (mountains). I was very impressed, and it gave me something to do on a boring drive.
Overall, in nearly 600 miles round trip I got about five CHP hits ... however, once I got to Nevada/Arizona my Redline went crazy, I could not get in my car for even a five minute drive without getting at least one 35.5 or 33.8 hit. Hell, within 30 minutes of crossing into Nevada I got four Ka hits, LOL. Talk about speed trap heaven ... I feel bad for speeders who live in such places. It was the suck.
