Wow, they must be doing a 4th of july crackdown in Detroit area -- my 1793 was beeping for almost the entire route till I got off the highway! Most were constant-on K-band from MSP (which was odd for me as I usually see MSP shooting constant Ka), there was one laser around a sharp curve. No alert from the high-mounted detector, but so many brakelights suddenly going on enteirng the curve that it works better than your new-fangled LED periscope lights ;-) LOL
on the radar encounters I averaged 0.75-1 mile heads-up -- plenty of breathing room. However, on the downside I've been noticing more and more false sources on I-94 and I-75. Lots of what appear to be constant-on K-band drones.
