Total Stations / Theodolites

Shopping Options
Total stations and theodolites are used for surveying, construction setting out, alignment and site measurement where accurate angle and position data are required. The right instrument depends on whether the work involves angle measurement alone or a combination of angle and distance measurement.
Celtic Surveys supplies total stations, electronic theodolites and the supporting survey equipment needed for field use. The range covers instruments for professional surveying and construction work, together with accessories for mounting, targeting and maintaining a stable measurement setup.
Total Stations and Theodolites for Surveying and Setting Out
Total stations and theodolites perform related tasks, but they are not the same type of instrument.
A total station combines electronic angle measurement with distance measurement, allowing surveyors and site teams to establish positions, set out points and carry out measurement work from a known survey station. This makes total stations suitable for a range of construction, engineering and land-surveying applications.
A theodolite is primarily used for horizontal and vertical angle measurement. It can be suitable for alignment, checking angles, setting out lines and other work where electronic distance measurement is not required.
Understanding this difference helps narrow down the type of instrument needed before comparing individual specifications.
Choosing a Total Station or Theodolite
The choice between a total station and a theodolite should start with the type of measurements required on site.
For work that combines angle and distance measurement, browse our Total Stations range. Different instruments are available for different survey requirements, so factors such as measurement range, angular accuracy, reflectorless capability and operating method should be checked against the work being carried out.
Where the main requirement is accurate angle measurement, our Theodolites category provides instruments intended for horizontal and vertical angle work.
Neither type should be selected on one specification alone. The required accuracy, working distance, site conditions and existing field equipment should all be considered before choosing an instrument.
Survey Accessories for Total Station Setups
A surveying instrument also needs suitable support and targeting equipment to create a practical field setup.
Tripods provide a stable mounting platform for total stations and theodolites, while prisms and reflective targets provide reference points for compatible measurement work. Prism poles, bipods, tribrachs and adaptors support positioning, centring and repeatable setup on site.
Rather than treating these as separate measurement systems, they should be selected to suit the instrument and the type of work being completed.
The Total Station Accessories category brings together the supporting equipment used with surveying instruments, including mounting and target-related accessories.
Compatibility is important. Thread size, mounting arrangement, prism type, pole connection and instrument requirements can vary, so individual specifications should be checked when adding accessories to an existing setup.
Choosing Survey Equipment for Site Work
Start with the measurements the job requires and then work outward to the instrument and accessories.
A construction setting-out task may require both angles and distances, while alignment or angle checking may only require a theodolite. Survey control work may also require suitable prisms, poles and mounting equipment so measurements can be repeated from consistent positions.
Working conditions should also be considered. Instrument accuracy, operating range, site access and the type of targets being used can affect the most suitable setup.
Where equipment will be used with existing survey accessories, check compatibility before ordering rather than assuming every prism, tribrach, pole or tripod will suit every instrument.
