Nautical Floor Standing Brass Theodolite. 62" detailed, functional, and calibrated. The azimuth and elevation axes can be read on a vernier scale with the aid of built-in magnifiers. Both axes have slow motion controls and the telescope can plunge and reverse to reduce bearing errors. With a magnetic compass mounted on top, the azimuth axis has a second spirit level mounted on the telescope with a mirror to assist in leveling while the telescope utilizes precision optics and has a brass lens cover. The theodolite's 22-power non-inverting telescope has two focusing adjustments; one for the precision reticule focus and another for focusing the target. The wooden tripod stand features smooth, polished round legs, each with brass fittings, and a screw release to let you adjust the height. A brass chain holds the three wooden legs together so the telescope can maintain its position. Theodolites are still used today for ultra high precision optical alignment and measurement. Â
