Protractor With Laser Mount. Designed for use with our high-powered BP-1 Trajectory Laser this twelve-inch protractor is used to find and photograph angles quickly and easily. The adjustable arm easily slides from 10° to 170° and can be locked into place once the correct angle is determined. The laser beam creates a consistent straight line without the possible sag of string, thus increasing accuracy. The protractor is also available in a kit, which includes both the protractor and the BP-1 Trajectory Laser.
