    Cobra XRS 9740 does the job! I have had many radar detectors since I have been driving and the Cobra XRS 9740 is very impressive. I actually purchased two for both my wife’s car and my truck. The day I recieved it I plugged it up, turned it on, and was attempting to install it on my windshield when it said “Ka Band Detected”. I was wondering what button I accidentally pushed when I noticed a sheriff’s car coming down the main road outside of my subdivision. The distance on mine is outstanding and my wife has had the same…

    Beep Beep… I use Radar Detectors in every vehicle and I have all brands… The most important thing I want to say about this one is… It does NOT have that ever annoying BEEP BEEP that penetrates through your skull that forces you to mute the thing and then you forget it went off and see the source of the detection!! IT HAS A PLEASANT TONE (as pleasant as a tone warning you about a speed trap can be…)!! And it even slowly fades quieter… Oh… I LOVE this detector! I plan on replacing all my others…
