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