More facts:

  • The aiming circle is basically a telescope mounted on a base which permits exact azimuth and elevation measurements.
  • The main housing is placed in a true level condition by two types of levels: the circular level is used for coarse leveling & the tube levels are used for fine leveling
  • A tube level on the elbow telescope permits the elbow telescope to be adjusted to a true horizontal line of sight.
  • A magnetic compass is located in an oblong box on the top of the main housing. The magnetic compass needle can be seen through a window or through the magnifier.
  • Zero azimuth heading with respect to magnetic north or any other selected compass heading can be made by turning the orienting knobs or the azimuth knob.
  • Elevation angle of the telescope is adjusted by turning the elevation knob.
  • Azimuth and elevation angles up to 85 mils can be read from the horizontal and vertical centerline on the reticle while looking through the elbow telescope.
