Is this post true "part being some local police departments can't use radar"
When an officer receives training for using time/distance detection equipment (VASCAR, Accutrak, etc.), is there a minimum distance recommended for effective use?
My son's science fair project is a demonstration of VASCAR, used in Pennsylvania by most local departments since they are not permitted to use RADAR. I'm setting up a computer simulator to allow the viewer to see what it's like to time vehicles and establish error margins.
I initially taped videos of different cars travelling a course of 100' marked by two milk jugs. But that distance seems way too short, hence my question. I sent an email to the manufacturer, but haven't heard back yet. I'm hoping they list a minimum distance in their manual that he can use.
Any help would be appreciated.
