Protractor with Laser Mount, 12"
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 degrees to 170 degrees 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.
