Advanced Theodolite for Surveying Testing - Digital theodolite is a cutting edge designing instrument for measuring bothhorizontal and vertical angles, It is a key device in surveying and building work. The theodolite comprises of a telescope versatile inside two opposite tomahawks the flat pivot, and the vertical hub. At the point when the telescope is pointed at a coveted protest, the edge of each of these tomahawks can be measured with incredible accuracy.
