Just wanted to start a thread to measure distances to cobra detectors. I had one today at a 1000 yds estimation. I'm running the STi-R 2,5,8 on rdr off and have notice Ka signals before then saw Cobras approaching. Today in light traffic had a Ka alert started looking then finally spotted the Cobra mount in the oncoming car from signal to visual was a good 1000ft. That's pretty darn sensitive who can beat it? Post to Boast.
