Wndsn Quadrant Telemeters
Description and use.
The Wndsn Quadrant Telemeter is a simple observational tool for measuring angles via various inputs combined with a number of means to directly process the acquired values.
Four Methods of Sighting
- Measuring angular size on the Telemeter (front) scale.
- Sighting the quadrant alongside the integrated ridges.
- Back-sighting the quadrant for sun observation.
- Sighting along the string for shadow square operation.
