This device is used to determine the angle of elevation to the top of any object. With this angle and knowledge of the distance to the object (baseline) it is possible to determine the actual height of the object by creating a scale drawing using the measured angle.
This device can also be used to determine latitude or the angle of elevation to the moon, stars or satellites.
The following pages show step-by-step how to construct and use this device.
It is possible to direct construction of this device from the Internet if you have a classroom with an LCD projector and Internet connection.
