South ET-05: electronic theodolite with vertical compensator and built-in memory for saving measurement results. Electronic theodolites of the ET series from South Survey & Mapping Instruments are convenient, reliable and very easy-to-use geodetic instruments. Large and clear numbers on the display almost completely eliminate error when reading data. The theodolite has 2 interface ports for exchanging data with external devices — a rangefinder and a PDA. The device is moisture-proof. Adjustment and adjustment of the theodolite can be performed independently (if the executor has the appropriate qualifications). Unlike many other models, theodolites have an automatic compensator.
