they use airplane, (vascar) laser alot(especially at night) for some reason and alot 90% or better use ka band and k band is all but non existent except in smaller towns now.
but working in palm bay driving everyday let me tell you they are tough.
workers are on this stretch of i-95 and watch out as the laser could be pointing at you. use alot of caution and order veil, a rd, and a jammer from roy if you need one as this area is blooming and as the moneys coming in so is the tax money to improve the police equipment. beware
