Protractor (Zero Line)

These 10” Protractors have been customized to start at a zero line and go to 180 Degrees--without having to cut off any tabs. Because of the way these protractors are made, they can easily be placed against a wall to run strings at a scene where bloodstain analysis is done. Made of heavy-duty, break-proof clear polycarbonate, they allow a string to easily be seen through the protractor to get a more accurate reading on the angle to run the string. When presenting evidence to juries, stringing is a great tool to show a three-dimensional display of where an area of origin is located.
