TheoLt Pro


TheoLt Pro adds professional computational functions to the TheoLt Suite.

By enabling full adjustment of control networks TheoLt Pro offers unrivaled flexibility to CAD survey drawing production. Full reporting of network condition, pre-and post closure analysis in both real-time and as logged data ensures no action is unrecorded. Distribution of station adjustment can be applied to detail sets to produce fully controlled site plans. Control and detail operations can be combined to eliminate repeat station occupations in building survey.

3D network control for building survey is simplified without compromising precision, the unique live ‘data sheet’ guides data acquisition with easy to read feedback to ensure poor sets are rejected and repeated before final computation.


TheoLt Pro makes use of a real-time method of monitoring control networks by least -squares adjustment. Open station naming, detailed QA reporting, shot selection and a live diagram in your CAD drawing all add up to a simple and effective method of achieving professional results.



TheoLt Pro includes the necessary tabulation, target recognition and computation tools for precise measurements to remote targets (such as façade control points for rectified photography) by intersection of angles. The technique is simplified by an easy to read results table and a live 3D ray diagram in AutoCAD.


The Pro module also adds full control for Robotic Theodolites to TheoLt Core module. No additional software is required for the instrument.
Add a Bluetooth or other wireless connection and one man surveying becomes a real possibility, with control moving to the point of measurement.
Working in conjunction with an as-designed drawing, as- built checks can be made quickly by using the drawing to drive the instrument. Differences are quickly identified and recorded.
Using the scanning functions, a cloud of points may be recorded for complex surfaces without resorting to expensive laser scanners.
