's "List of Laser Guns in what states" thread on RD.net List of Laser Guns in what states - Radar Detector Jammer Forum
Note here that he listed the prevalence of the LIDAR hardware in-order (information is as of this posting date).....
Pro Laser III
Note that Ohio is one of the states cited by several RD.net Forum members as being an early contract for the new LTI TruSpeed police LIDAR.
So far, there has been only one confirmed sighting of the TruSpeed, in southern Ohio.
I fully expect TruSpeed to be seen in Ohio, in the VERY near future.
