I've noticed in Arizona, cops don't use K/Ka at all. They use laser, or simply they aren't out patrolling the streets with radar. I saw a cop on a bike the other day shooting radar or laser, but I didn't have my detector yet.
It's like the only thing I can pick up are doors. What's really needed in Tucson is a GPS unit I guess? I don't know what highway patrol uses.
I've seen about 50 cops today, NONE running radar. Back in Albany, it was being blown up with K and Ka.
