They use mostly K band radar but I hear they also have Laser. They hide behind a variety of places that are hard to detect for the unwary. They write a LOT of tickets on this street. I’ve seen than point their gun at me while I was driving the posted 35 hoping that if they shake it at me hard enough it will change the reading. They are hard nosed as I found outback in 96 when a cop had actually clocked the wrong car( which turned before passing his motorcycle)
