More Arizona school districts turn to weapons detectors 

It’s something many have walked through - a weapons detector. You walk through them at a concert, or a sporting event, and now more Arizona schools are starting to use them. For a month now at Skyline High School in Mesa, students are getting used to a new norm. Weapons detectors are now set up at the entrances of the school. The weapons detectors are also portable and can be calibrated to different sensitivity levels and detect small knives up to firearms, depending on how a district decides to set them.
