C.L. Berger striding level 3.5 inch

Product Description

C.L. Berger Striding Level – 3.5 Inch Precision Surveying Instrument

This is a C.L. Berger striding level, a precision instrument historically used by surveyors, astronomers, and civil engineers for establishing level lines and performing precise vertical angle measurements. It measures 3.5 inches in length.

C.L. Berger & Sons, of Boston, Massachusetts, was a legendary American manufacturer of precision surveying and engineering instruments from the late 19th through the mid-20th century. Their tools were known for their exceptional quality and were considered the standard in the industry.

A striding level is a specialized type of spirit level designed to be placed on top of a telescope on an astronomical or surveying transit. By reversing the level (“striding” it) on the telescope, the surveyor could average out any errors in the level itself, achieving extremely high precision for vertical angle measurements used in geodetic surveying and astronomy.
