Angle Estimator -- paper diagram

$1.00

The angle estimator is used to approximate the azimuth (degrees east or west of true south or north), and the elevation (degrees above the horizon) of any object reflected in the Pathfinder's dome. Some state and local governments are now using the angle estimator to determine the azimuth and altitude of shading and transferring that information to their own required sun chart or forms.
