Why use a manual total station?

Manual total stations help surveyors, engineers, and construction workers measure distances and angles for a variety of projects, such as construction, mapping, engineering, and land surveying.

Why use a manual total station?

Surveying uses

Manual total stations are often used by surveyors to create three-dimensional maps of project areas, designs, volume calculations, and to verify as-built conditions or property boundaries.

Surveying uses

Construction uses

Total stations are also used in construction to lay out jobsites, check elevations, calculate the exact dimensions of structures, and to ensure that equipment and fixtures are installed in the correct locations.

 Construction uses

Civil engineering uses

Civil engineering projects often use these surveying instruments for mapping sites and measuring bridges, buildings, roads, railroad tracks, bodies of water, and critical infrastructure.

Which manual total station is right for your job?

Topcon’s GM-Series and OS-Series total stations operate with or without prisms (reflectorless), and feature powerful electronic distance measuring devices (EDMs), strong battery lives, and ample memory. They are also designed for rugged use and water resistance.

Choosing the right total station for your application involves considerations such as range, accuracy requirements, software functionality, and other factors. The following chart outlines key specification differences in Topcon’s manual total station lineup. If you are looking for solutions for one-person surveying jobs, machine control, or laying out large numbers of points, you may want to look at robotic total stations.
