Variety of theodolites

A theodolite has a telescope with diaphragm fitted in the center on a solid brass base.
Exquisitely designed and flawlessly crafted, our wide collection of theodolites: encompasses large, brass, dumpy, road level with stand, mini, antique and various others.

The Y theodolite differs from the transit in that the supports for the telescope are low, that the telescope rests in a cradle the trunnions of which rest on the supports, and that a segment of a circle attached to the cradle replaces.

Aerolotical Theodolite is very compact and light yet features a large 40mm main objective (20 power), 10mm finder scope (4 power) and gun site.
A unique aspect of this theodolite is that the reticule assembly is mechanically connected to the body of the theodolite not to the eyepiece tube.

The theodolite in case weighs only 6 pounds and 12 in its case as compared to the Warren-knight 20-8403 which is on the order of 40 pounds in its case.
Universal Theodolite Rangefinding is a small tripod-mounted high precision telescope with a total system magnification of 15x-60x and a dizzying array of dials, knobs, levels, and auxiliary lens systems, with which extremely high precision measurements of horizontal (``azimuth'') and vertical (``altitude'') angles are made.
