Doing some laser stuff today I pulled up to a new cvs pharmacy and I realized wait a minute sure is quiet. Yep no alerts. So, I thought wow they are not on k band anymore but now on x band. So, I turned on X band and got nothing. I thought ok lets try something else. I got my k band gun out and it alerted to it right away. Then after getting what I needed at cvs I drove 3 miles down the road and x band went off. So all bands are working but still no alert from the store. Is this something new or what?
