STONEX R20 Total Station

The STONEX R20 is a conventional total station designed for reliable measurement across construction, cadastral, mapping and stakeout projects. The R20 series includes three configurations: a 2″ model with 1000 m reflectorless range, a 1″ model with 1000 m reflectorless range and a 2″ model with 600 m reflectorless range.

All R20 versions can measure up to 5000 m with a single prism and provide millimeter-level distance measurement. The instrument uses a digital phase laser ranging system and an illuminated telescope reticle for clear target observation in different field conditions.

The R20 also includes onboard surveying programs, Bluetooth communication and USB data transfer. An external controller can be connected through Bluetooth when customized field software is required.

Why Choose the STONEX R20?

The R20 is designed for surveyors who need a dependable conventional total station without relying on a fully robotic or Android-based platform. Its three configurations allow users to select the angular accuracy and reflectorless range that best match their project requirements.

The long 5000 m prism range is useful for larger survey sites, while the 600 m and 1000 m reflectorless versions provide flexibility for measurements where placing a prism is difficult. The illuminated reticle, locking drives and trigger key also support practical manual operation in the field.

For construction, cadastral, mapping and stakeout work, the R20 provides a straightforward combination of measurement range, onboard functions and long operating time.
